The Worm's Feast

This spell is a part of the Bio Instability spell chain and can be found in the Bio Instability Rune Stone.

There is perhaps nothing more frightening than to watch yourself rot and be eaten. When the seniumancer calls upon this spell, they are attempting to conjure this very image itself. Pointing at the target, the seniumancer calls upon the dark and terrible symbol of decay magic, The Worm itself. The Worm works its way into the mind of the target and begins to feast, filling the target's vision of a terrifying hallucination which traps the target to that very spot. The target cannot move or act, witnessing in utter horror as their body appears to be covered with flesh eating worms devouring and feeding upon them. The target can attempt to make one Hard Insight check each round in an attempt to realize that the worms are not real and thus break free from the trap. However, should the target fail, the target will suffer 1d20 Vitality damage per round. If the target is able to escape the trap alive, they will find that while the worms were fake, the wounds left behind were very real. Until the wounds have been treated, should they be attacked by a critical hit they will be stunned for 1 round.
