Lassitude

Lassitude: Whenever a spellcaster with this spellblight casts a spell, she must make a caster check (DC 15 + twice the spell level of the spell being cast). If she fails the check, the spellcaster takes 1 point of nonlethal damage per spell level (or 1 point of nonlethal damage when casting a 0-level spell or 1 point per 2 caster levels if using a spell-like ability). This nonlethal damage cannot be reduced in any way so long as the spellcaster suffers from lassitude.

Creatures immune to nonlethal damage are immune to this spellblight.
