Cloak of the Bat

Rare

Wondrous item, major tier, rare (requires attunement) 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.

Boots of Speed

If you do, the boots double your walking speed, and any creature that makes an opportunity attack against you has disadvantage on the attack roll. If you click your heels together again, you end the effect. When the boots' property has been used for a total of 10 minutes, the magic ceases to function until you finish a long rest.
