Elemental Ammunition

You touch up to six pieces of ammunition, such as bolts or arrows, and imbue them with elemental energy. When a target is hit by a ranged weapon attack using one of the imbued pieces of ammunition, the target takes an extra 1d4 Acid, Cold, Fire, Lightning, Poison, or Thunder damage (chosen when you hit). The spell’s magic ends on the piece of ammunition when it hits or misses, and the spell ends when the six pieces of ammunition have been expended or after one hour.

Using a Higher-Level Spell Slot. The number of pieces of ammunition you can affect increases by two for each spell slot level above 1. Additionally, If you use a level 3–4 spell slot, the damage of the ammunition increases to 2d4. If you use a level 5+ spell slot, the damage of the ammunition increases to 3d4.
