Reactive Counter
Source
Character Operations Manual pg. 95
Whenever an opponent you’re aware of casts a spell, as a reaction you can cast dispel magic or greater dispel magic in an attempt to counter the spell, even if you didn’t ready an action or select that opponent. This magic hack doesn’t allow you to cast a spell that you don’t know, and you must expend a spell slot of the appropriate level to cast dispel magic or greater dispel magic in this way. You must know dispel magic or greater dispel magic to select this magic hack.
