Anti-Paintbrush

When used without paint on any item smaller than a 2ft cube, the item appears to be erased or camouflaged. The item still exists (can be held, used, etc.), but it cannot be seen. If used on a melee weapon, you must make a DC10 luck check each time the item is picked up. If you fail the luck check, take 1d6 damage before use. The effect lasts for 1 hour.
