Dual Energy Healing

You imbue a creature you touch with a precise balance of negative and positive energy, causing a stress to the creature's body along with the nudge for that creature to recover from the stress. The creature must expend a hit die to regain hit points equal to the number rolled + your spellcasting modifier. This spell has no effect on constructs, but the balance of negative and positive energy can be swapped to have an effect on undead creatures.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the creature can roll one additional hit die for each level above 1st.
