For the most part an add fight. Will get waves of adds and mini bosses until the boss finally comes out to play in P2.
Mini Bosses.
Lieutenant Krugruk requires that the raid members who engage him always make sure not to get hit by Arcing Smash Icon Arcing Smash, because the knock-back can throw players off the tower, causing great problems for the raid.
High Enforcer Thranok's lethal Skull Cracker Icon Skull Cracker can be avoided by simply running away from him as soon as he casts Crusher's Call Icon Crusher's Call. No one should try to survive the damage of Skull Cracker, not even tanks.
Master Cannoneer Dagryn's only problematic ability is Muzzle Spray Icon Muzzle Spray, for which raid members will have to dance for a few seconds in order to avoid being knocked back.
Adds, most can just be AoE'd down but Kor'kron Demolishers should be killed quickly as priority. Proto Drakes won't be able to be AoE'd and just need to be killed, not high priority though.
During P2 the melee need to spread at the back of the boss and the Ranged/Healers need to spread out, this is due to Flames of Galakrond some melee will be hit automatically, the ranged team then need to split into the person targeted who need to be furthest away from the boss and the rest that will soak, hopefully this means it won't 1 shot the intended target.
Apart from Flames of Galakrond, there is a DoT (Pulsing Flames) applied to the raid which acts as a soft enrage, this means heroism and all cd's should be used in P2.
