Simple Fel Bombardment (DH legendary)/ Throw Glaive tracker. I may or may not update this as time goes on.
This is set to only load when you have Fel Bombardment equipped.
Feel free to tweak as desired.
The number on the left is the number of Fel Bombardment stacks. It will glow when you've reached 5 (max) stacks.
The number on the top is the number of Throw Glaive charges remaining.
