Interweave Dispel
Feat 14
Source Pathfinder Player Core 2
Prerequisites dispel magic in your spell repertoire
You weave dispelling energy into a spell. If your next action is to cast a single-target spell against an enemy, and you either hit the enemy with the spell attack roll or the enemy fails its saving throw, you can cast Dispel Magic on the enemy as a free action, expending a spell slot as normal and targeting one spell effect affecting the enemy.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
SorcererThis indicates abilities from the sorcerer class.
SpellshapeSpellshape actions tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
