Elemental Infusion

You hold your weapon in your hands tightly as you let the very arcana inside of you flow into it. This causes the held weapon to gain an elemental attribute of your choosing. The now imbued weapon does 1d4 damage of that type plus its normal damage adding an extra d4 at 6th level (2d4), 10th level (3d4), and 14th level (4d4). At the expense of adding 1 point of exhaustion, at the end of 15 minutes, to the caster you can instead cast this spell and add 1d4 damage of all types, regardless of level, to your attack.

At 2nd level the caster can choose from acid, fire, and cold damage.

At 6th level the caster gains additional access to poison and necrotic damage.

At 10th level the caster gains additional access to radiant and lightning damage.

At 14th level the caster gains additional access to force and psychic damage.
