Absorb Elements

The spell captures incoming energy, storing it for your next melee attack.
You have resistance to the triggering damage type until the start of your next turn.
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.
using a spell slot of 2nd level or higher, damage increases by 1d6 for each slot level
