As an action, you can create a vial of liquid with hooked claws suspended in it. A creature can drink the contents as an action to grow tiny hooked claws that allow it to climb. The creature gains a climbing speed equal to its walking speed for the duration.

Augment

You can expend 1 additional catalyst so the creature can move up, down, and across vertical surfaces and upside down along ceilings, while leaving its hands free.
