Magic Items

While wearing this cloak, you have advantage on Dexterity (Stealth) checks. In an area of dim light or darkness, you can grip the edges of the cloak with both hands and use it to fly at a speed of 40 feet. If you ever fail to grip the cloak's edges while flying in this way, or if you are no longer in dim light or darkness, you lose this flying speed.
While wearing the cloak in an area of dim light or darkness, you can use your action to cast polymorph on yourself, transforming into a bat. While you are in the form of the bat, you retain your Intelligence, Wisdom,
and Charisma scores. The cloak can't be used this way again until the next dawn.
This cloak is made of hundreds of large, black feathers, and instead of transforming its wearer into a bat, this cloak allows its wearer to transform into a raven

This fearsome steel helm makes your eyes glow red while you wear it. This item can be found in Xanathar’s Guide to Everything.

This armor is obviously Githyanki in design. It is ornamented with tassels, ribbons, and bone fragments. Mithral is a light, flexible metal. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn’t. This item can be found in the Dungeon Masters Guide.
