Divine Star

You fire a holy bolt forward in a line 6 feet long and 5 feet wide in a direction you choose. For each creature in the line, you decide whether it is hurt or healed by the holy bolt. Roll
5d8. Creatures to be harmed must succeed on a Dexterity saving throw or take radiant damage equal to the amount rolled, or half as much damage on a successful save. Creatures to be healed instead regain hit points equal to half the amount rolled.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the amount rolled increases by 1d8 for each slot level above 4th.
