Wondrous Item, Uncommon (Requires Attunement)
The soles of these boots are living pads of clingspore, the same growth that lets shelf-fungus hang from a cavern's ceiling.
Sure-Footed Ascent. You have a Climb Speed equal to your Speed, and you can move up, down, and across vertical surfaces and along ceilings while leaving your hands free. The pads fail on surfaces slick with ice, grease, or blight-slime.
