Climb

A climb speed allows you to climb vertical surfaces and even ceilings as easily as walking on flat ground. You do not need to make Athletics checks to climb, and you move at your full climb speed on vertical and inverted surfaces.

While climbing, you are not considered to be in difficult terrain, and you can use both hands freely (unless the surface specifically requires handholds). If you take damage while climbing and fail a concentration check (DC 10 or half the damage, whichever is higher), you do not fall — a climb speed grants stability.

If you are knocked prone while on a vertical surface, you cling to the surface rather than falling. On a ceiling, being knocked prone causes you to hang rather than drop.

Without a climb speed, climbing a surface requires an Athletics check, costs double movement, and you must have at least one hand free to hang on. Falling while climbing without a climb speed causes normal falling damage.
