Ability Timers

Tips

• [Leytorrent Timing]: You can drink during any times that you’re in the ranged / healer stack point. Just let your other healers know. 
• [Efflorescence Placement]: Drop Efflorescence on the ranged stack point in the middle of the room. Aim for a high uptime. 
• The tanks can get quite far apart and you should assign one healer to watch over each. They won’t get hit too hard but you don’t really want even a single wipe to range issues.
• Start Rejuv blanketing:
  • 10-15 seconds before every Siphon Corruption (heavy).

Mythic

• [Leytorrent Timing]: Drinking during mythic is a little trickier and you’ll likely want to avoid it while you’re carrying the Flametouched debuff. Wait until you have Shadowtouched, or go down for a drink during the debuff transition when the bosses hit 50% life. 
• [Efflorescence Placement]: Depending on your strategy you can probably forget about Efflorescence while carrying Flametouched since you’re moving very frequently, particularly during the most dangerous parts of the fight. 
• You’ll frequently be out of range of half the raid in Mythic so consider picking up Germination to better keep your group alive.
• You can Displacer Beast back to your stacked raid if you get a Molten Touch / Siphoned overlap. Immediately go into Bear Form after blinking to maximise your odds of surviving this painful overlap.
• Start Rejuv blanketing:
  • 10-15 seconds before every Siphon Corruption (heavy).
  • 5-10 seconds before every Enflame Corruption (light).

Antoran High Command

The Antoran High Command fight ranges heavily in difficulty depending on how good your group is. A bad group will literally double the healing requirement and you’ll come to hate the mine-tripping idiots in your raid very quickly.

Average Fight Length: 5-7 minutes (Heroic), 7-9 minutes (Mythic)
Important Debuffs to add to your healing frames: Chaos Pulse (dispellable), Entropic Blast, Psychic Assault, Shock Grenade (Mythic)
Recommended Legendaries: Aman’Thul’s Wisdom, Chameleon Song, Velens
Recommended Talents: Cenarion Ward, Cultivation, Spring Blossoms, Flourish

Sample Healing Assignments (Mythic)

If you’re likely to see Fusillades 8 and 9 then you should move Aura Mastery and Hymn in the above screenshot to cover Fusillades 2 and 3 instead so that they can be used a second time.

Tips

• [Leytorrent Timing]: Pop your leytorrent during the fourth pod (that is, your second visit to the first pod). This phase of the fight has the lowest incoming damage. Just coordinate with your other healers since they’ll want to use this window themselves and your entire healing team sleeping in the corner at the same time isn’t a good look. 
• [Efflorescence Placement]: This is quite a movement heavy fight but the raid does tend to stack quite nicely in front of each pod. Each of the three bosses is up for 1:30 at a time which lines up almost perfectly with three Efflorescence casts. If you have 4T20 then save your Swiftmend bursts for Fusillades. 
• We are great candidates for sitting in the first pod since damage during the start of the fight is minimal. Cast Barkskin and Bear Form before you get in to counter the damage you’ll take inside. Picture a Bear trying to control the keys inside.
  • If you are picked you need to cast Chaos Pulse at all enemies to stack a big damage taken debuff. You’ll also need to hit all of the adds with Withering Fire whenever it comes off cooldown.
  • Get out at around 20-22 stacks. You can’t heal yourself in the pod so make sure you’re being looked after.
• Entropic Mines explode a few minutes after they’re dropped. This means you’ll get a big stack of 6-8 near the end of the third pod. You can either save healing cooldowns for this, or prematurely detonate the mines by standing on them to keep the damage stacks low. I’d recommend the latter since you’re already taking a beating during the third pod from Fusillade.
• Fusillade increases in damage as the fight goes on. Save your big cooldowns for the later Fusillades (but consider using one during the first also since it’ll overlap with Bladestorm from the adds which people tend to stand in. You’ll also have a Felshield Emitter to cover each of them and the raid should stack underneath the big shield.
• Don’t stand on any mines. Your melee are already going to stand on quite enough already.
• Start rejuv blanketing:
  • 10-15 seconds before each Fusillade.
  • Whenever 2+ mines have exploded.
  • About 3:20 into the fight half way through the third pod. If you’re not a super organised group then this is where you’ll get 5+ stacks of mines as they automatically explode.
• You should know: You can see who stood on mines by clicking on the problems tab in warcraft logs and then scrolling down to the Entropic Blast section.

Mythic

• In Mythic you’ll gain a third ability in the pod which you can use to shoot down bats which’ll attempt to dislodge you. It has a really long cooldown and bats come much more frequently than you can shoot them so your DPS will need to kill them from the floor.
• The only other change is the Shock Grenade mechanic. All three commanders have this ability and it’ll cause three targets to explode after 5 seconds dealing heavy damage in a medium radius and stunning nearby allies. You need to get this out of the raid immediately and you should use Bear Form to keep yourself safe while stunned.
  • Make sure you’ve added this to your frames since afflicted allies will need to be topped off before the damage hits. Consider Ironbark if the stun is going to overlap with a Fusillade or if they’re near a Bladestorming fel guard.

Portal Keeper Hasabel

Hasabel summons three different portals over the fight (at 90, 60 and 30% HP) and you should only need to assign 1-2 healers to join the portal team. Any healing class can do the job fine.

Average Fight Length: 5-7 minutes (Heroic), 7-8 minutes (Mythic)
Debuffs to add to your healing frames: Reality Tear (Tanks), Felsilk Wrap, Everburning Flames (Dispellable), Cloying Shadows (Dispellable, Mythic)
Recommended Legendaries: Prydaz, Chameleon Song, Aman’Thul’s Wisdom, Velens
Recommended Talents: Cenarion Ward, Cultivation, Spring Blossoms, Flourish

Tips

• [Leytorrent Timing]: You can Leytorrent between Felstorm Barrage casts. Aim to drink while there is no active portal since they do quite a lot of ticking damage that you’ll want to be casting for. 
• [Efflorescence Placement]: There’s about 30-40 seconds between Collapsing World casts. You want to drop Efflorescence outside of the circle where the ability will hit so that you don’t have to move it prematurely. You won’t get 100% efficiency because everyone’s moving around to dodge Felstorm Barrage but it does enough to justify the cast. 
• Active portals deal significant ticking damage to the raid, and then a smaller stream once closed. You want to dedicate most of your resources to healing through active portals and you should hold back otherwise to conserve mana.
• Fiery Imps cast Fiery Detonation which explodes for heavy raid damage if not interrupted. We can actually help out here with Typhoon, if necessary.
• Start rejuv blanketing:
  • 10 seconds before each Collapsing World… collapses. It’s actually a long cast so you can start throwing leaves as it begins. Make sure you time a Wild Growth with the collapse to maximise that Dreamwalker value.
  • During active portals, as mana allows. Make sure you’ve still got some fuel in the tank for the end of the fight where you’ll be healing through significant ticking damage.
• You should know: You can actually survive a Felstorm barrage hit in Bear Form, even in Mythic. You should proooooobably just dodge it anyway.
• Portal Tips coming soon.

Mythic

• Not much changes from a healing perspective on mythic. There’s just much more damage going out and you’ll need to allocate your mana carefully to stretch it to the end of the fight. The same principles apply as in heroic and you’ll want to cut back on the number of rejuvs you’re putting out while there are no active portals up (especially at the beginning of the fight). Make sure you’re using your efficient heals frequently (Wild Growth and Efflorescence in particular), squeeze in as many cooldowns as you can (Flourish, EoG especially) and don’t forget about your leytorrent.
• You still only want to send one healer up to the portals, and sending any more will leave your core team low on healing.
