Weapon Bash
From Final Fantasy Wiki
Weapon Bash is an ability gained by Dark Knights in Final Fantasy XI once the player reaches level 15. The ability can be used once every 5 minutes. When used, the Dark Knight will use his weapon to strike the enemy. It does a small amount of damage; however, its true application is its ability to Stun a creature and interrupt spell casters. It is relatively unreliable for stopping creatures' special abilities. This ability does create a large amount of enmity, similar to the fighter skill provoke.
