Wondrous Item, 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.
Notes: Advantage: Stealth, Set: Innate Speed (Flying), Movement, Shapechanging, Deception, Outerwear
hmm very op
Perfect for my Dexterity based Dhampir Vengeance Paladin. Yes, I'm Batman.
I'm the hero Gotham deserves, but not the one it needs.
I'm freaking batman
There's a question we ran into with this in-game that we can't find an official answer to. When using this item to fly, there's no weight limit listed. What would be a blocker to lashing a teammate to yourself and flying them across an area?
For example, we got ruled down when I (Aasimar) tried lashing my teammate (Halfling) to myself to fly across an area, even though they weigh less than the kit I normally carry. Where can we find official numbers on weight limits or rulings on what we can/can't carry with Cloak of the Bat?
Genius!
When in doubt, use carrying capacity, Add the weight of the character your carrying and their equipment to the weight of your equipment, then use encumberance rules.
