The Light of Ophanim

You channel the fading light of the Archangel Ophanim. As an action, you reach out to touch a creature within range. A radiant handprint is singed into the creature's skin in burning light and glowing heat. Slowly, the radiant burn will grow outwards, consuming that part of the creature's body with vengeful flame.

The creature must succeed on a Constitution saving throw. On a fail, the target takes 4d10 fire damage, and on a success, they take 1d10 fire damage.

The burn mark will eventually subside to the original handprint, which a lesser or greater restoration spell can only remove. 

The spell increases by 1d10 for each spell level cast above 3rd.
