Feat: Stolen Spell

Trigger You critically succeed at a saving throw against an enemy's spell, or an enemy critically fails a spell attack roll against you.

As you perfectly counter a spell, you re-aim its magic to use it yourself. You gain the ability to cast the triggering spell one time before the end of your next turn, even if it's not on your spell list or is of a higher rank than you can cast. This doesn't cost you a spell slot or other resource. If you cast it as part of a Spellstrike against the creature that originally cast it, that creature is Off Guard against your Strike. Use your own spellcasting statistics for this spell, as you do for other spells you cast.
