Transfer Vitality

Siphon life energy from one willing creature to heal another. Select two living willing creatures within 30 feet of you and each other and apply one of the following effects based on the casting time:
- 1 action: One target loses one hit dice, and the other can immediately expend it, restoring hit points equal to the dice roll + the target's CON modifier
- 1 minute: One target loses up to two hit dice, and the other target can add them to its own hit dice. This cannot exceed the target's maximum number of hit dice
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, increases the number of hit dice spent or added by 1 for each slot level above 1st.
