There is always a way to die more or less quickly in a raid fight...
T1: Stand in front of Caudecus and let him get damage stacks.
T2: Enrage.
T4: Let the enemies wail on you.
T5: Wall.
T6: Stand in briars.
T7: Screw up with voices or stand in front of Melusine.
T8: Trigger towers at the same time to force an enrage mechanic.
T9: Wall.
T10: Electric ground.
T11: Barofield, Kaliya's cleave, middle of the room during adds phase.
T12: Revelation, adds phase, fountain
T13: Wall

If you cannot find a way to instantaneously die, and can't beat the fight... like what are you even doing at that point?
