Dragonscale Talisman

This small talisman made from the scales of a lesser dragon enhances your connection to draconic magic. While wearing it, you gain a +1 bonus to all spell attack rolls and spell save DCs. However, the talisman is infused with the essence of its draconic origin, causing you to have a lingering scent of smoke, which bestows disadvantage on Stealth checks. Additionally, the strong draconic aura attracts unwanted attention from dragonkind; you have a disadvantage on Charisma checks made against dragons and dragon-related creatures.
