Ring, unknown rarity (requires attunement by a Must give DJ a hug because you are his best friend.)
DJ gives gemmed amulet with SMA engraved on it. You notice DJ has a similar amulet that has SH on it. One you give DJ a hug you would solidify BFF status. This item will become fully attuned. As a reaction if the wielder of the amulet that you can see takes damage you can redirect the damage to yourself instead. If the new target would drop to zero hit points the effect does not occur and the original target takes damage as normal.
Notes: Must give DJ a hug because you are his best friend.
