Check: You can walk on a precarious surface. A successful
check lets you move at half your
speed along the surface for 1 round. A failure by 4 or less means you can't move for 1 round. A failure by 5 or more means you fall. The difficulty varies with the surface, as follows:
Being Attacked while Balancing: You are considered flat-footed while balancing, since you can't move to avoid a blow, and thus you lose your Dexterity bonus to AC (if any). If you have 5 or more ranks in Balance, you aren't considered flat-footed while balancing. If you take
damage while balancing, you must make another Balance
check against the same DC to remain standing.
Accelerated Movement: You can try to walk across a precarious surface more quickly than normal. If you accept a -5 penalty, you can move your full
speed as a
move action. (Moving twice your
speed in a round requires two Balance checks, one for each
move action used.) You may also accept this penalty in order to
charge across a precarious surface; charging requires one Balance
check for each multiple of your
speed (or fraction thereof ) that you
charge.
