You channel arcane energy into one simple or martial weapon you’re holding, and choose one damage type: acid, cold, fire, lightning, poison, or thunder. Until the spell ends, you deal an extra 1d4 damage of the chosen type to any target you hit with the weapon. If the weapon isn’t magical, it becomes a magic weapon for the spell’s duration.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the die to 2d4. When you use a spell slot of 5th level or higher, increase the die to 3d4.
