I'll also add that the dreadnaughts in turn 8 have a enrage as well. Flamethrower deals 11kish damage which is pretty much a oneshot in addition to all the damage getting thrown around from the dread.

Turn 6 in addition has bee's must kill them or bee will enrage and kill players one by one until it dies. 3rd phase has the slug/slime mechanic thats a dps check, basically you need to either Destroy raffleshia before 10 stacks of acid ooze builds up or do super slug and kill it before it aoes the entire party for 30k damage and then kill raffleshia before 10 stacks build up.

Turn 9 also has another dps check the ghosts, need to kill em before players gerot twist debuff reach a certain stack or they will die since they can't cure themselves of the status without running into the lights that are droped by the ghost.
