Comprehensive Barrier

As a reaction, you may cover your body in a thin layer of blank magic that, once struck by a spell, will report back to the caster all available information on said spell including name, spell slot level, effects, duration, and components needed to cast. A Wizard who casts Comprehensive Barrier may roll an intelligence saving throw where the DC is 14 plus the level of the spell striking the Comprehensive. On a successful save, you may copy this spell into your spell book.
