Steal Spell

When you use Legendary Thief to steal the impossible, you can steal a prepared spell or spontaneous spell from a foe. The spell is randomly selected from the highest-level spells the foe knows that have a target or area, to a maximum of 8th-level spells; the target loses the appropriate spell slot as if they had cast it themself.

You can Cast the Spell once within the next dice: 1d4 rounds, after which the fleeting magic fades; this otherwise works the same as casting a Loaner Spell.
