Your magical energies cling to enemies, interfering with their spellcasting.
BENEFIT
Targets affected by a disruptive spell must make concentration checks when using spells or spell-like abilities (DC equals the save DC of the disruptive spell plus the level of the spell being cast) for 1 round. Targets that avoid the spell’s effects avoid this feat’s effect as well.
MP Increase: +1 (a disruptive spell costs 1 additional MP more than the actual MP cost of the spell.)
