Destiny's Smite

The next time you hit a creature with a weapon attack before this spell ends, the weapon swirls with rainbow colored threads as you strike. The attack deals an extra 2d8 of a random damage to the target. This damage is rolled as a d4, where a 1 is fire, 2 is lightning, 3 is poison, and a 4 is cold damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the extra damage increases by 1d6 for each slot level above 2nd.
