Shadow Venom

Your poison enables you to blend into your surroundings.

• Venomous Cloak: As a bonus action, you can secrete a camouflaging poison over your skin for 1 minute. While cloaked, you gain advantage on Dexterity (Stealth) checks, and creatures have disadvantage on Wisdom (Perception) checks to detect you.
• Silent Strike: If you make an unarmed attack against a creature that hasn’t detected you while cloaked, the attack deals an additional 1d6 poison damage, and the target must succeed on a Constitution saving throw (DC = 8 + your Dexterity modifier) or be poisoned until the end of your next turn.
