Elemental Strike

You brandish the weapon used in the spell’s casting with elemental energy of your choice between fire, lightning, cold, and acid, and make a melee attack with it. On a hit, the target suffers the weapon attack’s normal effects and elemental damage equal to your SpellCasting Modifier. Furthermore, the elemental energy can be spread around by making a broad strike. Up to two creatures within 5ft of the original target will receive elemental damage equal to your SpellCasting Modifier if the attack roll would hit them as well. 

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 elemental damage to the target on a hit and to the adjacent targets as well. The damage rolls increase by 1d8 at 11th level (2d8) and 17th level (3d8).
