This add-on will help you to keep track of your Inner Fire during combat, so you know when to reapply it.
The add-on is a simple small box that you can place where you want. When your Inner Fire only has 10 charges left it will show itself telling you how many charges you have left (as shown on the image).
When it reaches 5 or less charges it will change color and message (still showing the amount of charges left), to let you know that it's getting close now.
When it's completely a small "flash" effect will happen in the box to let you know that it's been completely depleted and the message left in the box will also tell you that (and will stay there until you reapply Inner Fire).
This allows you to always know the status of your Inner Fire, for instance in PvP, when you need to know about it (when it starts getting low). Quite useful when you have a rogue or such wailing at you, eating up charges. This way you can make sure your Inner Fire is always active to mitigate some of the damage.
You can access a few options by typing "/ifw" and following the instructions.
The add-on is a conversion of Ice Barrier Watcher made to fit with Inner Fire.
There might be a few options not yet activated and the add-on still needs to be finished, it does however work as it should and what's missing is basically just "bonus" stuff.
