This is a three phase fight.  The first phase involves protecting the roots at the back of the platform (initially behind the boss) from puddles of fire.  The second phase involves us protecting the NPC's as they move across the platform to heal the tree.  Finally, the third phase is simply nuking the boss whilst staying alive.

NORMAL TACTICS:

Phase 1

• Pull him towards your edge of the platform and keep him fairly close to the leading edge, allowing space for fire swirlies.

• Firestorm - fire swirlies, avoid.  

• At the same time as Firestorm, some will get big red circles .. leaves fire puddles .. overlap previous fire puddles.

• Stacking debuff needs to be dispelled - Aflame.

• Dream Rend - a shadowflame tear in space .. run away.  Damage reduces with distance.

• Tank facing away from raid.  Tank swap at two stacks of Fyr'alath's Mark (40 second debuff).

Intermission (70%)

• Boss leaps into the air and lands as Dragon .. bouncing/knocking back players.

• DPS down his shield before he finishes casting Corrupt.

• Don't stand in Flame breath.

• The pools from the edge change to fire balls moving towards boss.  Intercept.  Causes debuff.  Tanks soak.

• Phase ends with a knockback.

Phase 2 

• Avoid slam location.  Tank in centre.

• Spirits will spawn at edge - heal to full health which makes them immune to damage.

• Firestorm - avoid fire swirlies. Causes two big Infernals adds - one per tank.  Kill asap.

• Firebreath along centre of the platform - avoid.  This will spawn adds.

• CC/kill adds asap.  If a spirit touches one, the spirit dies (markers for location callouts?)

Phase 3

• Bloodlust after knockback when the phase starts.

• Blue seeds around the room - can be picked up and moved.  If they take any damage, they will do pulsing raid damage.

• Pick up seeds and avoid all damage.

• Deep breath - boss turns and does frontage.

• Avoid Fire tornadoes.

• Avoid red fire swirlies.

• Red arrow/red circle - if you have that and seed, drop the seed and run away to avoid damaging seed.

• Apocalypse Roar - massive damage.  

• Anyone with a seed gets an extra action button that drops a green circle on the floor - dip into that to gain a shield for Roar.

• Use one seed per roar.

• Tank debuff - Internal Maw.  Tank swap when needed to help mitigate ramping damage.

HEROIC TACTICS:

• Blaze - Players explode in flames .. move away.

• Fire balls from Intermission causes the debuff to stack.
