Crusher Tentacle: Melees hard, has a ton of HP and has an aura that reduces damage done by the raid by 20%, stacks with other crusher tentacles so these must go down fast. Melee-ing these will interrupt their aura but they gain a temporary buff that increases their damage and attack speed when they are hit so this is dangerous if they are being DPS'd.

Corruptor Tentacle: Casts various debuffs, Curse of Doom, Apathy, Draining Poison and Black Plague. Dispellers will need to be on the ball. These are interruptable.

Constrictor Tentacle: These have very little HP and appear underneath random players, grab them and hoist them into the air doing damage every few seconds until killed.
