Vestige of Khaeleth

You channel the selfless nature of Khaeleth to protect your allies. You take 2d6 damage, and one ally that you can see within 30 feet gains temporary hit points equal to the number rolled you take plus your spellcasting modifier. If you have less than half of your hit points left, the damage taken by you is halved.

Additionally, the first time the ally is hit with a melee attack, if they have any temporary hit points remaining, the enemy that hit with the attack takes 2d6 + spellcasting modifier radiant damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage and temporary hit points granted increases by 1d6 for each slot level above 1st.
