Welcome to Dragon Soul Heroic mode for Ultraxion. In this guide, I will run you through everything you need to know about how to best utilize your Resto Shaman spells and abilities for a healing showdown.
And so you come to face the ultimate creation of Deathwing. You’d think he would show more appreciation about his wife son and daughter, his own family, but no. Before the fight starts he makes it very clear.This dragon is his pride. Like a dog if you will. Faithful puppy. Only tad bigger.Makes you wonder what he might eat for breakfast. For now his appetite consists of you and your party. Fear not however because once again you find yourself in the company of the four aspects. And Thraal. No comments. In the heroic version of this fight not many things change. He hits you harder, has a tougher enrage timer to beat which is complicated by his upgraded health pool and of course, now 2 additional players need to soak each Hour of Twilight while the tanks and the dps try to handle additonal Fading Lights by using Heroic Will .Take into consideration that this time you only have 3sec down from 5sec before you lay your bones to rest when Ultraxion casts Hour of Twilight. Other than that as a healer, like in normal version you only have to be concerned about Hour of Twilight since yet again you won’t be affected by Fading light.
Note. Keep in mind that depending of what addons you’re using Heroic Will button might not be visible. Or if you are like me you don’t want to drag your mouse all over the screen while healing. So make the following macro and bind it to the key of your preference or even your mouse.

Suggested Raid Composition
2 Tanks – 2 Healers – 6 Dps
Gear and Reforging Check
For this fight, you will need to be able to sustain your mana all the way through the encounter up until the end the 5min mark when Ultraxion will start to cast his Unstable Monstrosity ability every second.This means that probably since you’ll be spamming healing rain and pretty much everything else you can afford before you down him you will be gasping for mana.There are ways to make your life a little easier and your spells more effective.
Before the 5min mark even though you will be 2 healing it be prepared for minimal damage or for what I would call dps time. Not only because you’re bored but also because your raid will probably need your 3 – 5k dps you will provide. Equip your talent tree with Telluric currents to get mana back as well as do damage and Focused Insight to be able to amplify your healing throughput.
You will be stationary for the whole fight so feel free to sacrifice your ghost wolf and since no dispelling is necessary remove a point from that too. If you are progressing on Ultraxion with minimum gear, you and the rest of your team , then probably you will want to invest some points in your elemental tree (2 points in Acuity,3 points in Concussion, 3 points in Elemental Precision ) to achieve 2 things. Higher dps from you and higher mana return from your lightning bolts. If you are looking at his after the % nerf or your gear is higher then feel free to leave your talent tree as is.
Below is an example of how your character should look like. Gear, reforging, talent tree and glyphs included.
Haste in this example is as close to 916 as it gets. I’ve removed all extra haste to amplify my spirit and mastery needs.Also the only time you will really need haste is after the 5min mark of the fight were you will have heroism and spiritwalkers grace to compensate.
Mastery should above 20 or as close to it as possible for the extra healing it will provide you for when your raid hits all time lows. Mastery is a must in this fight since your raid after the 5min mark will always be below 50% of health.Its scary I know.But you’re a shaman. embrace your mastery and watch your numbers fly.
Spirit is little above 3800 (counting the proc from Heart of Unliving ) in order to have enough to dump at that late stage of the fight. Believe me, you will not have time to cast lightning bolts to get any back.
All items used are from Normal Dragon Soul.
As always, if your gear is different just apply the rules above for potential reforges.
Assigning the Healing Buffs
There is often a disagreement on which crystal a shaman should take in this fight. As you know they are 3. The red buffs you with Gift of Life which provides a 100% increase to all the healing done by the affected player(s). The green buffs you with Essence of Dreams which provides valuable AoE healing, which will prove extremely useful, especially as the encounter progresses. Note that this buff applies to most types of heals, including HoTs and AoE heals (such as Healing Rain). Finally the blue buffs you with Source of Magic which provides increased casting haste and reduced mana cost, making it desirable to all healers.
So which one should you take? Lets start with the one you shouldn’t which is the blue. As you and most other healers will have either the Red or Green buffs by this point, the Blue buff is most desirable to Holy Paladins, who can practically spam Holy Radiance until the end of the fight, generating a huge amount of AoE healing. So unless there is no paladin in your team just erase the blue crystal of your mind.
As it goes for red or green. Both are excellent for shamans but my choice of preference will be green. You see with red yes you get a 100% increase in all your spells.That means 100% increase in all healing rain ticks, in all riptide , in chain heal. Sounds nice? However think of this. How much nicer does it sound for every greater healing wave to become instantly your new aoe spell? At the end of the fight you will be spamming healing rain and chain heal like crazy if you take the red. But if you take the green you’ll be cruising with healing rain ( that heals the same either with red or green) and greater healing waves. Every healing wave will hit all your raid making it much greater than ANY buffed chain heal would even be. Also think of this. If you are healing with a paladin they will not be healing the tanks at all at the end since they will be spamming Holy Radiance .This is where you come to steal the show with healing the tanks with greater healing waves which since you have the green buff will ultimately heal the raid also with an insane amount. If you need further proof feel free to check WoL with top healers. Paladins rule the first pages then come shamans with Essence of dreams in their highest heals having taken green buff.There is no red buffed top shaman healer. You will not fail with red, but green is definitely a winner for you.Let the druid take the red then the blue and enjoy them.
Top 2 Shaman healers as found in WoL‘s page for top healers for Ultraxion HC 10man.
Gravatize his logs found here with 74.645k hps had 17.3% based on Essence of dreams.Used green buff.
Voidwalker his logs found here with 70.055k hps had 32.5% (making this by far his first healing spell) based on Essence of dreams.Used green buff.
Preparation Tips and Tricks
Make sure your weapon is imbued with Earthliving Weapon enchant and your Water Shield is up . Put Earth Shield on the tank that is currently tanking and try to keep it up at all times .Start overhealing the tanks so that your well spent Ancestral Healing talent points will proc that wonderful 10% damage reduction and 10% maximum health pool increase. After you see you can’t climb more on their health cast riptide on them.As long as riptide is ticking the stacks will never drop thus securing the tanks an extra 10% damage reduction and health pool increase throughout all the fight.
Fight starting in 5..4..3..2..1. Pull.
You have quite a lot of seconds before Ultraxion hits you with his first Hour of Twilight that you will need to avoid using Heroic Will.
Note.Shamans have no mitigation making us bad candidates for staying out with the other 2 designated dps or tank to absorb Hour of Twilight .
You should put your totems down before Ultraxion lands and lay a healing rain .Make sure you stay behind or at the sides of your raid at all times if you have Maw of the Dragonlord equipped. Start spamming Ultraxion with lightning bolts and depending on the situation this will be your priorities :
Before and up until 5min mark :
2.Lighting bolts if nobody needs healing or if healing is sufficient.
3.Riptide on cd on the tanks and earth shield on the current tank or at least the main tank.
4.Chain heal if you think healing rain will not top off your raid in accordance with your fellow healer or greater healing wave if you see the tank falling a little too low or people coming out of soaking hour of twilight. Keep your riptides rolling to keep up with your tidal waves (healing rain DOES NOT consume one charge) or chain heal to bring them back up.
After 5min mark :
1.Healing rain on CD,make sure you use any shock spell you might have before that if you feel you can afford the GCD to amplify it.
2.Healing waves on the tanks if you have green buff. If you have red buff forget that spell and move on to…
At this point its only a matter of if you can afford the GCD’s to maintain earth shield and riptide and my only advice is head into the fight and after few wipes you will know for yourself.
About your CD’s.The fight will last from 5:00 min to 6:00, usually varying around 5:30. Your mana tide totem has a 3 min cd which means you can only use it 2 times into the fight.Drop it a little bit before 2 min into the fight and then again a little into the 5th min.This way you will utilize your 2pc set bonus if you have it. Use your spiritwalkers grace at 1 min mark,3 min mark and just after heroism has faded( around 5:30min mark) or a little before that to gain that extra haste you will need for the last phase. As for your spirit link totem , use it whenever you feel like to but make sure you have it for around 5:30min mark into the fight in accordance to any raid CD your fellow healer has and after Nozdormus Timeloop buff has faded from most of your raid.
Note. About heroism there is a nice trick quoting Malevica from Type H for Heals:
The double-lust trick
You have a dilemma: you really want to give the healers the Bloodlust or Heroism or Time Warp for the end of the fight, but the best time to use it is the very start, where you can line up BL with trinkets, pre-pots and DPS cooldowns.
But you can have your cake and eat it too! Heroic Will takes you into a different realm, so you can’t be affected by buffs or debuffs,including BL and Heroism.
So here’s how to use this to your advantage:
1. Have a countdown timer for pulls. (You already have this though for timing pre-pots, right?)
2. 2 seconds before the pull, have your healers hit Heroic Will
3. Just as the pull is made, pop BL/Heroism/Time Warp. Your healers won’t get the buff but they don’t need it, and crucially they also won’t get the associated debuff
4. At the 5-minute mark, pop a second BL/Heroism/Time Warp so the healers can benefit from it
This concudes this guide for the Ultraxion HC healing showdown. Remember to use your Heroic will a second before Ultraxion casts Hour of twilight. Enjoy the fight and happy looting!
Welcome to Dragon Soul Heroic mode for Yor’sahj The Unsleeping. In this guide, I will run you through everything you need to know about how to best utilize your Resto Shaman spells and abilities for a healing showdown.
Yor’sahj The Unsleeping has, much like Morchok The Douchekeeper , one main distinction from normal mode. It appears that he’s inspired by Alien so he spawns 4 oozes at a time instead of 3 hence leaving you with the option of having him absorb 3 at the end of their trail rather than 2. I remember when I first saw the normal version in PTR and in various early videos I was left thinking that blizzard has a sick sense of humor. Much like real life. Where you THINK you have a choice when in reality you have almost none. There are 6 combinations that you will encounter randomly in no specific order in this heroic mode fight and in each you have mainly only one choice of what to kill. It sounds scarier than it actually is however.In order to help you with that I suggest installing the addon called Yor’sahj Automatic RaidWarnings that calls out which ooze to kill and lets you know which ones are left.
Purple – Gives everyone (except pets) Deep Corruption. Every time someone is healed, they get a stack. If they reach 5 stacks they explode, doing massive damage to the raid.
Red – Yor’sahj will cast Searing Blood on 8 random raid members, doing more damage the further away they are.
Green – Yor’sahj will cast Digestive Acid, which does moderate damage to random targets which will splash to everyone within 4 yards of them.
Yellow – Gives Yor’sahj Glowing Blood of Shu’ma which makes him attack 50% faster and use his abilities twice as often.
Blue – Creates a mana void. This will drain everyone’s entire mana pool. When it is killed it will explode and return the mana to everyone within 30 yards.
Black – Spawns small adds which will focus on random targets and use Psychic Slice.
By this point you should have run at least once the normal mode of this fight. If you were thrown in the heroic version and you need a catch up below are some guides to help you better understand all the in and outs of this boss and for a more in depth analysis of what each ooze will do.
1. Guides for Normal Yor’sahj
TIP : Always watch some videos beforehand to be in the know.
2.Videos for Heroic Yor’sahj
TIP : For this fight specifically it’s very important to be able to properly handle Deep Corruption so you will need to have it showing on your healing addon raid frames. The spell ID is 105171 and it’s name is Deep Corruption. If you have VuhDo just go to your configuration screen on the Debuffs tab and then click on Custom. Make sure you have Stacks clicked on both columns then go and find the spell from the dropdown list.
Suggested Raid Composition
1 Tank – 2 Healers – 7 Dps
Gear and Reforging Check
For this fight, you will need to be able to dump your mana fast enough in very little time in order to heal your raid. This boss is characterized of the huge amounts of dead time that provides to the healers, making this fight especially easy for Resto Shamans. Equip your talent tree with Telluric currents to get mana back when no healing is needed and Focused Insightto be able to amplify your healing throughput.You will mostly be stationary for the whole fight so feel free to sacrifice your ghost wolf and since no dispelling is necessary remove a point from that too. Below is an example of how your character should look like. Gear, reforging, talent tree and glyphs included.
Haste in this example is around 2005 in order to help you cast faster and give your riptide one more tick.
Mastery should above 18 or as close to it as possible for the extra healing it will provide you for when your raid hits all time lows.
Spirit is little above 3200 (counting the proc from Heart of Unliving ) in order to have enough to dump with your fast spells.
All items used are from Normal Dragon Soul as this is an entry level Heroic boss.
Preparation Tips and Tricks
Make sure your weapon is imbued with Earthliving Weapon enchant and your Water Shield is up . Put Earth Shield on your tank and keep it up at all times .Start the tank so that your well spent Ancestral Healing talent points will proc that wonderful 10% damage reduction and 10% maximum health pool increase. After you see you can’t climb more on his health cast riptide on him.As long as riptide is ticking the stacks will never drop thus securing the tank an extra 10% damage reduction and health pool increase throughout all the fight.
Fight starting in 5..4..3..2..1. Pull.
Run with the tank and stand behind the boss. Drop your totems at your location.
Before the Oozes. Since nobody is getting any damage besides the tank focus on him. Renew his riptide if needed and heal him with greater healing waves or sustain him with healing waves if he doesn’t drop too low.
Casting of the Oozes. After a few seconds he will start casting for the first set of oozes. This is your major downtime where no healing whatsoever is required so as soon as the tanks health is full start casting lightning bolts to fill your mana pool back up.
Merging of the Oozes. Healing on this phase is very dependant of the combination of the oozes. There is a total of 6 possible combinations as following. Unless there is a green ooze up ALWAYS stack under the bosses bottom. No excuses if you don’t.
—> Purple – Red – Yellow– Black
Kill Yellow to control some of the damage. With Red up you’ll need to stack and with purple up you will need to handle Deep Corruption . Below is a list of how all shaman spells and how they react to the debuff.
—> Chain Heal – 1 stack for each person it bounces to. (Not recommended )
—> Earthliving Procs – NO STACKS
—> Earth Shield – NO STACKS
—> Healing Rain – 1 stack upon entering. If you leave and re-enter, you gain another stack.
—> Healing Stream Totem – NO STACKS
—> Riptide – 1 stack on initial application
—> Spirit Link – NO STACKS
—> Unleash Elements (Earthliving) – 1 stack
Tip. Divide your raid into 2 groups of 5 before you start the fight.This way every healer will be left with a group of 5 to heal through.
Tank assignment. Refresh Earth shield if it drops and cast riptide just a sec before the oozes merge. Unleash your weapon at a hunters or warlocks pet if you can’t afford another stack on another member. This will boost your next direct heal for 20%. Remember your mastery will boost your heals the lower the targets health is, so feel free to allow the tank to drop a little below 50% before you heal him with a greater healing wave. You only have up until 4 heals before you blow him up and the raid so it’s crucial to maximize your heals as much as possible before you heal anyone. So while keeping an eye of the tanks health Unleash life and spam the boss with any shock spell to take advantage of your Focus Insight talent that will give you an additional boost. Always heal the tank with amplified greater healing waves.Keep your tidal waves up by casting riptide on cooldown which will gradually heal members up while only giving one stack and make your next casts much faster. If anyone is in danger heal them with greater healing wave.
Raid assignment with no tank. While you don’t have the tank to heal don’t forget to refresh his earth shield if its lost. Heal the raid members as stated above and have in mind to heal the tank in case of an emergency with an instant amplified greater healing wave. You may place a healing rain down, in a 10man it will not wipe the raid but have a discussion with the other healer first.
—> Purple– Green – Black – Blue
Spread for more than 4 yards since Green is up. Handle Purple as above. With a twist. Depending if this is the first time you encounter Blue. If it’s the first time it will of course drain you of your mana.Drop mana tide totem to gain as much back as possible and if you can afford it cast lightning bolts at the boss. (If your raid uses the tact where you don’t kill the first mana void. At the second mana void your raid will kill the first so you’ll never run out of mana but in any case keep your mana tide totem for the possibility of running into a bad case of mana void. Otherwise always replenish your mana by casting lightning bolts during downtime. )
—> Green – Red – Blue – Black
Stack since Red is up. Handle Blue as above. Drop healing rain on cooldown, refresh riptides on cooldown, chain heal from the lowest and cast greater healing waves at people that are fixated from the Black adds. If someone is in big trouble spam 2 healing surges on them followed by greater healing wave.
—> Green – Yellow – Black – Red
This is the hardest combination.You should keep all your healing cooldowns for this.Start the phase by casting heroism (or anyone in the raid that can afford wasting mana on Heroism or Time warp.) Pop your Spiritwalkers Grace in you have a 4pc set bonus for the extra haste but save it for at least 10 sec into the phase. Converse with the other healer about when to drop your spirit link totem.Either start with it or drop is AS SOON as the other healers cooldown fades. Spam the boss with any shock spell on cooldown to amplify your next healing rain and keep casting chain heals in between.If anyone is low or even worse the tank use greater healing waves to patch them up.
—> Blue – Black – Purple – Yellow
Handle Blue as above. Handle Purple as above.
—> Blue – Purple – Green – Yellow
Spead 4 yeards and handle Blue and Purple as above.
This concudes this guide for the Heroic Yor’sahj healing showdown. Always cast lightning bolt while Yor’sahj is casting forth the oozes. Unless there is a Green Ooze up ALWAYS stack under the boss. And in case there is purple ooze up please DO NOT use chain heal. Enjoy the fight and happy looting!
Welcome to Dragon Soul Heroic mode for Morchok. In this guide I’ll run you through everything you need to know about how to best utilize your Resto Shaman spells and abilities for a healing showdown.
Morchok has only one main difference from his normal version. When he reaches 90% of his health he’ll go into an early life crisis and develop a multiple personality disorder. It’s not treatable by medication and as you’ll probably have read in many guides like Type H for Heals or Icy Veins your best option will be to divide and conquer. This will leave you with 2 teams of 5 ( or another set up for 25man ) and probably your team will include 1 tank, 2 healers and 2 dps.
Equip your shield if you haven’t already since Stomp is doing physical damage and your shield , for example Ward of the Red Widow will give you an extra 12201 armor which is equal to about 13.66% increase of damage mitigation bringing you to approximately 53% damage reduction depending on your gear. Your best bet as restoration shaman is to soak the damage with the tank while the other healer and the rest of dps run around soaking the damage from the Resonating Crystals. Fun times. The reason for this is that although as healers we bring a lot to our raid, the one thing we don’t bring is mobility. The less the restoration shaman has to move the more healing throughput he will have. Staying with the tank and having a good communication with him secures you with at least half as running around as you would have to run otherwise. (If your raid leader decides you won’t soak , then buckle up for some tough love )
Preparation Tips and Tricks
Make sure your weapon is imbued with Earthliving Weapon enchant and your Water Shield is up .Know your team and your tank. I suggest running with a good healing addon like Grid or Vuhdo that will keep your groups together. Put Earth Shield on your tank and keep it up at all times ( stating the obvious but ok ).Start overhealing yourself and the tank so that your well spent Ancestral Healing talent points will proc that wonderful 10% damage reduction and 10% maximum health pool increase. After you see you can’t climb more on your health riptide yourself and the tank. As long as riptide is ticking your stacks will never drop thus securing you and the tank an extra 10% damage reduction and health pool increase which will be life altering for this fight. Always refresh both riptides as they are about to expire and a small tip. Refresh the tanks right before you start running out for the black blood phase. This will secure him with the debuff even if he runs the opposite way of you so you don’t have to build it up as soon as you reach him again.
Fight starting in 5..4..3..2..1. Pull.
Run with the tank and drop your totems in between the location where Morchok is now and to where the tank will start tanking his split version. This way you get to benefit from your totems as much as possible without having to recast them and lose mana in the process. Have DBM ( or any other raid warning addon ) let you know when the stomp is coming. Depends on your healing assignment but probably you won’t have to heal your tank just yet. Be sure to keep him and yourself riptided and feel free to spend your third riptide at the raid member of your choice.
Tip. Remember you can only have 3 ppl riptided maximum in your raid if its glyphed so if you are unsure of your uptime keep it down to yourself and the tank. Best however to learn to always cast it on cooldown this will give you the most throughput.Fill your time before the first stomp with lightning bolts to keep your mana up ( provided you’ve spent points in Telluric Currents ).
Before the Stomp.Make sure you and the tank are as close to 100% health as you can get.When DBM tells you the stomp is being cast and has between 4 to 2 seconds left on the counter start casting healing rain ( If you have spend talent points in Focused Insight squeeze that in before the healing rain). This will ensure your rain coincides with the stomp timer perfectly thus minimizing your overhealing and saving you some precious mana.
After the stomp.Spam heal the tank who by that time will be gasping for air.There are many ways to do that, an effective one is either use an instant heavy heals macro (check my Resto Shaman Macros post for reference) or cast a riptide to keep your tidal waves up and consume both with Healing surge.Chain heal your group of 5 to as close to full health as possible and proceed to follow the tank and set camp at his location.The trick here is to put your healing rain in such a strategic location that it will include all 5 members of your party everytime you put it down. To that end ask your party to stay close enough and IN healing rain outskirts up until they need to run to take the damage of the crystal. (Now it depends if you are at the Morchok side or the Kohcrom side you will have different set of stomps and crystals. Healing wise the Morchok side is harder due to the fact it has one more additional stomp and one more crystal to deal with ). Be sure to keep your riptides on cooldown and as priority have yourself and the tank at full health before each stomp.Also don’t forget to spam riptide while running and unleash your weapon.I suggest you use unleash at the end of your run and cast a greater healing wave on the tank if he needs it by that time.
Resonating crystal time.Once the resonating crystal spawns it takes 12 seconds to detonate.Within this time a stomp will occur, all 5 members need to soak that stomp before running to the crystal if this happened to spawn that far. Otherwise the tank is responsible to bring Morchok closer to the Chrystal to make it easier for the party. While Morchok is pounding on the tank try not to panic. Be on the lookout for every stomp and every crystal. Before the stomp make sure you and the tank are as close to 100% health as you can get. Achieve this by casting greater healing waves or chain healing the tank if you can afford to lose his riptide.
Before and after the next Stomp.3 seconds before the stomp cast healing rain and 1 second before the stomp cast greater healing wave on yourself. Precasting that will land you with an immediate much needed heal as soon as your health drops. While healing rain, riptide and probably other hot procs are ticking on you and the tank chain heal the other 3 members that will already be running for the crystal. Drop healing rain at their location and by then the tank will have dragged Morchok close enough on them for him to be in that healing rain also.Run to his location as soon as you are done casting the rain, chain heal the 3 players that will soak the crystal damage and prepare yourself for the next stomp.If everything looks ok by this time squeeze in one or two lightning bolts and drop your mana tide totem.After it expires replace it with healing stream totem again and keep dropping it on cooldown preferably right before a black phase and right before a stomp.
Black Blood Phase.Repeat as above till the black blood phase. As soon as your feet hit the ground riptide the tank and leg it till you find a secure spot behind pillars. While on the run riptide yourself also and if someone needs little health unleash your weapon on him and start casting lighting bolts at the boss till the black blood phase ends from behind a pillar. Run towards the tank and pop spiritwalkers grace so you can heal on the run. Go through your healing rotation as above but before that make sure you re benefiting from your totems.Check your buffs and recast if needed. When your spiritwalkers grace is on CD heal with riptides and Unleash life. For the people with 4 pc set bonus.Make sure you keep one spiritwalkers grace for when the boss is below 20%.You will need it as soon as Heroism buff is over ( assuming you cast it at 20% of the bosses health ). If everything worked out the boss will be dead and you ll get hopefully a nice new bis neck piece to show off for your efforts.
Tip.For shamans with the 4 pc set bonus. Save your spiritwalkers grace for just before heavy stomps.
This concudes this guide for Heroic Morchok healing showdown.
Tips and quick summary
Have your weapon enchanted, keep water shield on you and earth shield on the tank at all times.
Preheal yourself and the tank for the extra Ancestral Healing buff and keep riptides rolling on him and yourself to keep the buff going 100% of the fight.
Precast Healing rain 3 seconds before each stomp ( provided you and the tank are as close to 100% health as possible ) and precast greater healing wave on yourself the last second.
Cast Chain heal on the other 3 members while they are running for the crystal and drop a healing rain at their location. Run to the tank and heal him and yourself while preparing for the next stomp.Use a heavy instant heavy healing macro if you can’t afford the casting time or take advantage of your tidal waves that proced from either your previous chain heal or riptide and consume both with healing surge.Throw some extra heals on the rest of the party. Fill your downtime if any with lightning bolts.
Before the first Black blood phase drop mana tide totem and keep dropping it on cooldown after that. Remember to recast healing stream totem after mana tide is exhausted.
As soon as Black Blood phase is active riptide the tank on the run and yourself , unleash weapon to a member than needs it and as soon as you are safe start casting lightning bolts behind a pillar.
Pop spiritwalkers grace on your way back to the tank and prepare for the next black blood phase as above after step 3. Recast your totems if you feel they are too far away from your location.
Pop Heroism on 20% of the bosses health and if you have 4pc set bonus remember to cast it as soon as hero fades.
