Conjure Minor Elementals

You conjure spirits from the Elemental Planes that flit around you in a 15-foot Emanation for the duration. Until the spell ends, any attack you make deals an extra 2D8 damage when you hit a creature in the Emanation. This damage is Acid, Cold, Fire, or Lightning (your choice when you make the attack).

Using a Higher-Level Spell Slot: The damage increases by 1D8 for each spell slot level above 4.
