Chromatic Blade

You touch one willing creature and evoke a blade of energy into their hand. The blade has a design that you can choose, but is one-handed, light, and treated as a simple weapon. You choose acid, cold, fire, lightning, poison, or thunder, and the blade will inflict 3d8 damage of that type on a hit, which uses your spell attack modifier. Until the spell ends, the creature can use the blade as a weapon it can wield and is proficient with. If the creature lets go of the blade, it disappears, suspending the duration remaining but not the concentration, but they can evoke the blade again as a bonus action before the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
