5-level Abjuration (ritual)

Choose up to six creatures in a 30-foot-radius sphere centered around yourself. You temporarily gain hit points equal to the sum of each creature's maximum hit points. Any damage that would normally be taken by each creature, you take instead. When the duration ends, any temporary hit points that are left are lost and you return to your hit points just before you cast the spell. If you take more damage than the temporary hit points you gained at the casting of the spell, the damage is applied to your remaining hit points and normal rules apply.
At higher levels: When you cast this spell using a spell slot of 6th level or higher, the duration increases by one round for each slot level above 5th.
