Dawnfire

You offer a prayer of protection for a friend in need, and a burst of holy light comes to their aid. Choose one ally you can see within range. Each enemy within 5ft of the chosen ally must succeed on a Constitution saving throw or take 1d4 radiant damage. The chosen ally then gains 1d4 temporary hit points if at least one creature fails the saving throw. 

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
