Disrupting Aura (abjuration, aura, primal) 30 feet. Formian mageslayers are surrounded by an aura of disruptive energy that disperses magical energy and makes spellcasting difficult for their enemies. Whenever an enemy creature within the aura attempts to Cast a Spell or Activate a magic item, they must roll a DC 5 flat check; on a failed check, the spell or activation is lost and the action is wasted. Free action activations disrupted by this aura can't be attempted again until the start of the activating creature's next turn.
