Armadillo Cloak

The outside of this cloak has a rough, leathery texture, while the inside is soft like velvet, and the cloak itself is large enough to swaddle your whole body. The cloak has 5 charges and regains 1d4 charges each day at dawn. As an action on your turn, you can draw the cloak around yourself and speak the command word, expending a charge as you do so and causing it to harden into a sphere that fully encloses you. Then as part of the same action, you can move up to your speed by rolling along the ground. During this movement, you can move through hostile creature’s spaces as if they were difficult terrain, and when you move through a creature’s space, make a melee weapon attack against it. On a hit, the attack deals 1d6 bludgeoning damage plus your Strength modifier. At the end of your movement, you gain a number of temporary hit points equal to the damage dealt this way.
