Chromatic Channeling

You cloak yourself in abjurative magic to deviate some of the incoming damage to a creature near you. Choose a creature within 5 feet of you. That creature has to make a Dexterity saving throw. If it fails, the target takes up to 10 damage of the triggering type, but never more than half of the original damage roll, and you subtract that amount from the damage you take. If the target succeeds, it takes no damage, but you can still subtract the amount of damage it would have taken from the damage you take.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the maximum transferable damage increases by 5 for each slot level above 2nd.
