Casts Invalidation (cureable), putting tank stats down to zero, a medium range AE arcane stun, canceled when you take damage.
Defilers can cure Invalidation with their cast while stunned cure. Use mage that are at max range for attack spell to cure priest that are at max range for heal. Manastone does NOT work. Tribal Spiritists hat DOES work. It is possible, but unconfirmed, that standing directly in front of the mob may not take the AE. Will need a couple more tests to see if it was just dumb luck or an actual safe spot.
