Aura of Sacrifice

Divine energy radiates from you in an aura with a 30-foot radius. Until the spell ends, the aura moves with you, centered on you. Each round the spell remains active you take 2d4 + your spellcasting ability modifier of necrotic damage, transferring to nonhostile creatures (not including you) equal to your spellcasting modifier within the aura that regain a number of hit points equal to half the total suffered by you. Their hit point maximum cannot be exceeded. This aura ends after 1 minute or if you take damage from any other source.

If your health is reduced to 0, you fall unconscious for rounds equal to the most recent roll. Once conscious, you gain 1 hit point for each round you were unconscious.

At Higher Levels. When you cast this spell using a spell slot 6th or higher, the dice increases by 1d4 for each slot level above 5th.
