Unless otherwise stated, a knock down lasts 2 seconds; it can be extended to 3 seconds using Stonefist Insignias or certain skills. Junundu Tunnel and Reaper's Sweep can knock down for 3 seconds; three other skills can knock down for 4 seconds (Choking Breath, Backbreaker, and Psychic Instability). A knocked-down target cannot be knocked down again until they get up; however, they can be knocked down again the instant they begin to rise (see quarterknocking).
Some foes carry Stun on Critical Hit, causing knock down to foes against whom they score a critical hit. Others carry Stun Immunity which prevents them from being knocked down. Characters inside a Siege Devourer or Desert Wurm are immune to knock downs.
A small number of foes, including Shiro Tagachi, can be difficult or impossible to knock down for other reasons.
- The warrior armor upgrade component Stonefist Insignia increases the duration of all knock downs inflicted by the Warrior by 1 second. This upgrade cannot extend durations beyond 3 seconds.
- The skill Earthbind sets a minimum duration of knock downs to 3 seconds. It also bypasses Stun Immunity, but has no effect on other skills that prevent knock downs.
