Boon of the stars

Choose a creature that you can see within range, as a shimmering field appears around them. For the duration, the target is resistant to fire or radiant damage (your choice), and their first weapon attack that hits each turn deals an additional 1d4 damage of the same type. This spell's damage increases to 1d6 when you reach 5th level, 1d8 when you reach 11th level, and 1d10 when you reach 17th level. At Higher Levels. If you expend a spell slot of 1st level or higher when you cast this spell, it is no longer concentration, and persists for 1 minute or until the target falls unconscious or dies.
