Your vengeful nature flows through your magic, turning your enemies against themselves.
Only enfeebling spells that affect a single target and can be negated with a successful Will save can be trick spells. If the target fails its Will save against a trick spell, in addition to the spell’s normal effects, the target also clumsily hinders itself. Immediately attempt a special combat maneuver check (1d20 + your caster level + your Charisma bonus) to perform a dirty trick combat maneuver against the target. Any feats you have that apply to dirty trick maneuvers (such as Greater Dirty Trick) also apply to this check.
MP Increase: +1 (a trick spell costs 1 additional MP more than the actual MP cost of the spell.)
