Corpselight

A will-o'-wisp that starves to death might rise as a cold, blue, glowing sphere of spongy wetness—a corpselight. A corpselight instinctively seeks out a host corpse to dwell within, as its physical form quickly deteriorates if not hidden within a dead creature.

Sidebar - Advice and Rules Larger Corpselights

A typical corpselight can animate only a Small or Medium corpse, but particularly powerful corpselights can inhabit larger bodies. Their basic abilities remain the same, but the damage they deal and the DC of their Death Light increase as appropriate for their increased level.
