Fluid Combat Overhaul is a combination of two different types of mods: the Fluid Blocking and Fluid Attacking mod.

Fluid Attacking

In the Fluid Attacking mod, it is possible to use the Attack key to perform attacks. The direction of the attack can be changed by using the X and Y keys of the keyboard.

The keybinds are set to default keys that you would never really press during gameplay. It is recommended to swap the Attack key with Fluid Attack and the Defend key with Fluid Defend to be able to make use of most of the mod's functionalities.
