Fast Climbing is a way of quickly climbing vertical walls by inwardly Wall Jumping on it. It can typically be done on walls that can be mantled with an air jump. The main benefit of Fast Climbing is that it allows you to climb walls that would’ve taken an air jump.

Fast Climbs do not consume any Stamina.

Fast Climbing allows you to scale buildings easily without burning stamina. Without Fast Climbing, you could air jump and waste one stamina bar; or wall jump and Heavy Melee, which is slower and debuffs your subsequent Wall Jumps for two seconds..

To Fast Climb, look directly at the wall you want to climb. While moving into the wall, wall jump holding the forward movement key. If you are close to the edge, you will automatically mantle; if not, you can air jump, Heavy Melee or use another movement option to climb the wall.
