Pure single target fight – Except hands….

There are 3 pools (orange, purple and green) around the boss.

Fight has 4 mechanics that are empowered depending on which pools of energy he absorbs.

Pound: Large AOE damage that creates splash damage 4 yards around every raid member. Stay spread.
Shadow Waves: Spawns waves from the purple pool that travel in random directions which need to be avoided.
Explosive Runes: Multiple runes spawn that grown and after 6 seconds will explode for raid wide damage. Need to pop these early by running over them before they all expire at the same time. If you run over, only the soaker takes damage.
Grasping Hands: Kromog hands grip the whole raid and need to be killed ASAP. Need to stack for these and kill them VERY quickly.

When the boss is empowered with a pool the following abilities are changed and the tanks get an extra mechanic to deal with per pool.

Empowered with Purple: Shadow Waves will spawn from EVERY pool. Try to be close to a wall. Not in the middle of the room.
Tanks: Large magical damage attack that will knock you back a LONG way. Make sure your back is to the wall.

Empowered with Red: Explosive Runes will respawn once soaked if another rune is not close to it. Runes respawn in front of where you were running to when you were running into the rune to soak it. You need to run into the runes from behind and “herd” them into the middle towards each other to despawn them all.
Tanks: Explosive debuff. Same idea as the Mark of Chaos from Imperator Margok. Rooted but transcendence should would to get you away from the raid.

Empowered with Green: Kromog hands slowly move towards the closest pool after spawning. Just kill ASAP as normal.
Tanks: An extra hand will grasp the tank and will have more health and do more damage. Kill is as soon as other hands are dead.
