You attempt to absorb the magical effects of a spell to revitalize yourself. When a creature casts a spell within range, make an ability check using your Spellcasting Ability. The DC equals 10 + the spell’s level. On a success, the spell has no effect and you regain hit points equal to 1d6 per level of the triggering spell + your spellcasting ability modifier. (Minimum Hit Points Gained: 1d6 + Spellcasting Mod.). Should you fail the ability check, the triggering spell's effects are unaffected.
