Court of the Seelie

You summon Feywild magic to bolster your allies. You create an aura of Feywild energy in a 30-foot radius around you for the duration. While in this aura, creatures of your choice within the radius have advantage on saving throws against being charmed or frightened, and when they hit a creature with an attack, they deal an extra 1d6 radiant damage. The aura is also infused with fey magic, causing any creature that enters it for the first time on a turn to take 2d6 psychic damage.
