Prowler’s Helm– Wondrous item, rare (requires attunement)
Though similar in appearance to traditional helms worn for battle, the colors of this helmet are muted, consisting entirely of greys and blacks. While wearing the prowler’s helm, you have advantage on Dexterity (Stealth) checks made to avoid being seen. In addition, whenever you begin your turn in dim light or darkness, you become invisible until the start of your next turn or until you take an action. While wearing the prowler’s helm, if you make a melee weapon attack against a creature that has not seen you and the attack hits, that attack is an automatic critical hit.
