One Piece

Crafted from soft, breathable black silk lined with a hidden weave of sea dragon thread, this cloth mask covers the lower half of the face, concealing identity and intention. While wearing this mask, you have advantage on Charisma (Deception) checks to conceal your emotions or identity, gain a +1 bonus to Dexterity (Stealth) checks in dim light or darkness, and can mute your voice magically for up to 1 minute as a bonus action, allowing you to cast spells without being heard.
