Elemental Shield

As a reaction, this spell conjures an invisible barrier of magical force that captures some incoming energy, lessening its effect on you and storing it for your next melee attack. You have resistance to the triggering damage type until the start of your next turn as well as a +2 bonus to AC, including against the triggering attack. Also, the first time you hit with a melee attack on your next turn, the target takes an extra 1d6 damage of the triggering type, and the spell ends.
