The flail has a swing cooldown of roughly 1 second. It takes four hits to knock an opponent down and five to kill. Due to its wonky swing animation, hits with this weapon are rather unreliable. Also after knocking an enemy down, you will have to stomp to finish them.
The flail is not recommended for usage due to a swing animation that has varying range and direction. However, if used, the flail can extend its hitbox by spinning during a swing.
