Devotee's Censer

Weapon (flail), rare (requires attunement by a cleric or paladin)

The rounded head of this flail is perforated with tiny holes, arranged in symbols and patterns. The flail counts as a holy symbol for you. When you hit with an attack using this magic flail, the target takes an extra 1d8 radiant damage.
As a bonus action, you can speak the command word to cause the flail to emanate a thin cloud of incense out to 10 feet for 1 minute. At the start of each of your turns, you and any other creatures in the incense each regain 1d4 hit points. This property can’t be used again until the next dawn.
Proficiency with a flail allows you to add your proficiency bonus to the attack roll for any attack you make with it.
