You channel positive energy to prepare a target for the damage it will take. At the completion of the casting, the target is surrounded by a halo of light. If the target takes damage before the duration of the spell is done, the target instantly heals 1d4 hit points and the halo is discharged. If the target is reduced to zero hit points, the target heals damage and does not gain the dying or wounded conditions, nor does it fall down.

Heightened (+1) The amount of healing or damage increases by 1d4.
