⟜ Requires Restoration

Tweaked from 5eYou already know this as 5e Holy Aura — It's your Holy Aura reworked into a lower-level personal protective bubble — instead of advantage on all saves plus blinding attackers, this 30-ft aura grants nonhostile allies disease immunity, poison resistance, and advantage on saves against a list of conditions.
Cast a 30-foot aura: disease immunity, poison resistance, save advantage vs. blinded, charmed, frightened, paralyzed, poisoned, and stunned.

Purifying energy radiates from you in a 30-foot radius. Until the power ends, the aura moves with you, centered on you. Each nonhostile creature in the aura (including you) can't become diseased, has resistance to poison damage, and has advantage on saving throws against effects that cause any of the following conditions: blinded, charmed, deafened, frightened, paralyzed, poisoned, and stunned.
