Climb Or Swim

If a creature's speed entry includes the word “climb,” they can climb across vertical and horizontal surfaces at full speed. Likewise, if a creature has “swim” in their speed entry, they can swim in liquid at full speed.

Creatures without those types of movement can still climb or swim when a rule allows them to move, but each square of climbing or swimming costs 2 squares of movement. If a surface is difficult to climb (for instance, a sheer cliff or ice-covered wall) or a liquid is hard to swim through (a raging river or whirlpool), the Director can call for a Might test. On a failure, a creature can't climb or swim but wastes no movement in the attempt. The Director can also impose other consequences to failure, such as being caught in the spinning current of a whirlpool.
