Elemental Imbuement

You channel elemental energy into a weapon you are holding. Choose one damage type: acid, cold, fire, lightning, poison, or thunder.

As part of casting this spell, you must make a melee or ranged weapon attack with a weapon you are proficient with. On a hit, the attack deals its normal damage, and the target takes an additional 1d4 damage of the chosen type.

If the attack misses, the spell fails and has no effect.

On a hit, you can cause the weapon to briefly flare with elemental energy, shedding dim light in a 5-foot radius until the start of your next turn.
