Devil-Beating Brush (Patreon)

Wondrous item, rare

Many temple murals depicting great gods and deities have been painted by artists wielding devil-beating brushes, which are blessed by divine magic. While the brush is being held, a constant stream of paint coats its pegasus-hair tip. While holding it, you can use a bonus action to change the paint's color. You gain a +5 bonus to any ability check you make with the brush to paint. The paintbrush counts as a set of painter's supplies.

You can use an action to paint on a devil. Make a Dexterity or Charisma check using the paintbrush against the devil's AC. On a success, the devil takes 4d6 radiant damage. If you roll a 20 on the ability check, the devil must also succeed on a DC 15 Charisma saving throw or be banished to its home plane of existence, unless it's already there.

"Ya just beat the devil out of it. That's the best part."
