This spell, based on the ability of the mythical land of Toruna to prevent spellcasting, is designed to hamper spellcasters. It creates a slight imbalance in the target's mind, forcing her to make a concentration check (DC 15 + the level of the spell being cast) each time she casts a spell. Failure indicates that the spellcasting was botched.

Material Component: Any monothot.

All or part of this spell is open game content, as described here.
