Properties
While wearing this uncommon wondrous item, a creature gains advantage on one Charisma (Deception) check per short rest. Once per dawn, after observing a creature for at least one minute, the wearer can copy that creature’s clothing and voice for one hour. This functions as disguise self, except the copied voice is included.
Lore
Reliquary docents used these obsidian-and-silver clasps to demonstrate historical costumes without handling fragile originals. Curator Veyl quietly modified several brooches for agents who acquired exhibits from unwilling owners.
Game Master Guidance
The copied disguise is visual and audible, not physical. It does not provide memories, passwords, mannerisms, or changes that withstand touch. Reward players who spend time observing a target, and let suspicious NPCs test knowledge or behavior rather than negating the item automatically.
