Facemauler is a spell recommendation mod for feral druids in cat form. It takes the current state of the game (buffs on you, debuffs on your target, CP, Energy, etc), and recommends the best move to do next. It was written because the Cat priority list is very complicated, and is still a work in progress. It is for single target only, and doesn't consider Cat Swipe.

There are two seperate icons for Clearcasting and Berserk. Berserk recommendation can be disabled in the options. There is also a slider to adjust how much time must best left on rip to use FB

There is an option to disable FFF suggestion. Users can also choose how many CP to use SR at via a slider in the options.

The mod attempts to predict your second move after suggesting your first one. It does this by displaying two smaller icons. One for if your current move generates 2cp, and another if it generates 1. This is disable-able via the options menu.
