Clasp of the Octopus

Uncommon, wondrous item (requires attunement) This ornate silver clasp, shaped like an octopus gripping a pearl, can be affixed to any cloak. When worn, the metal feels cool and damp. While attuned to this clasp, you gain the following benefits: Grasp of the Deep.

This item contains 2 charges. As a bonus action, you may consume one of these charges. For the next minute, you can move up, down, and across vertical surfaces and along ceilings, while leaving your hands free. You have a Climb Speed equal to your Speed. However, this item doesn't allow you to move this way on a slippery surface, such as one covered by ice or oil.

Inky Escape.

When you take damage, you can use your reaction to release a burst of ink, heavily obscuring a 10-foot radius around you until the end of your next turn. You can then immediately move up to 10 feet without provoking opportunity attacks. Once used, this feature cannot be used again until you complete a short or long rest.

Abyssal Adaptation.

You can breathe underwater.
