simple question here in a recent encounter we had a Balor demon. Witch has an ability as follows
"When killed, a balor explodes in a blinding flash of fire that deals 100 points of damage (half fire, half unholy damage) to anything within 100 feet (Reflex DC 33 halves). The save DC is Constitution-based."
does this ability still work if said creature is disintegrated or would that prevent that? if not what ways would a wizard/sorc be able to prevent abilities like that
thanks in advance
