Arcane Barrier

You call upon the fabric of the world around you to create an invisible magical barrier protecting a creature within range. Target a creature you can touch, and for the duration of the spell, they have a barrier protecting them with its own hit points. The hit points of the barrier must first be depleted before the protected creature takes any damage or condition that might otherwise be inflicted upon it. The hit points of the barrier equal your spellcasting ability modifier (Minimum of 1 hit point). The spell ends when you lose concentration, the duration is up, the hit points of the barrier are depleted, or you dismiss the spell (no action required).
