FoA Watcher is a very small addon designed to help you keep track of the Fury of Angerforge trinket stacks. When you get a stack the FoA icon will appear with a countdown similar to your buff frame. When you reach 5 stacks the icon will glow to indicate that you can use the trinket.
Type /foa for options.
/foa lock = locks/unlocks the fame to be freely positioned.
