Colliding Bodies

Many effects in the game -- such as the throw maneuver (see Combat Maneuver Options) -- can cause a creature to crash into a wall or other obstacle. When such a collision occurs, each involved creature must succeed on a Hard (4+) Agility test or fall prone. An incapacitated creature fails automatically. A creature ignores this rule if it is more than one size larger than the body it is colliding with.
