Your Charisma score is increased by 2 and your Dexterity score is increased by 1.

As a bonus action, you can touch the inside of your wing to open your cheiropocket or close it again. While it's open, your wings emanate the glow of the Astral Sea, and you can stow or retrieve an item as an action.

Your cheiropocket can hold cubic feet of nonliving material up to 12x your Intelligence modifier (minimum of 12 cubic feet). If you attempt to stow living material, or an item that's too large, it passes through your wing and falls to the ground behind you. You take any damage that the pocket's contents deal to its interior. If you fall to 0 hit points or die, the pocket's contents spill forth, unharmed.

 The space of your cheiropocket cannot exist in the Astral Sea when your body is also present there. Traveling to the Astral collapses your cheiropocket and leaves its contents behind in your space the moment you cross over.

While your arms are free and and you are not wearing heavy armor, you can extend your wings to fall at a speed of 30 feet per round. For ever foot you descend, you can also move a foot horizontally (this costs movement as normal).

While in the Astral Sea, bats have a flying speed of 40 feet regardless of armor worn, and can hover.

As a bonus action, you can emit a sound that's silent in the Beast World, but a loud shriek in the Astral Sea. Anything in the part of the Astral Sea that crosses within 120 feet of you (such as a creature using the etherealness spell) becomes visible to you until the end of your next turn. While in the Astral Sea, this ability gives you blindsense out to a range of 120 feet instead. You can use this ability a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

You can add your proficiency bonus to Intelligence checks to perform astralcrafting. Additionally, you know the Charles' chunk* cantrip. Intelligence is your spellcasting ability for this spell.
