1/21/21 Shadowlands - Fire Mage
This WeakAura overlays on top of the default blizzard UI aura proc indicators for Heating Up and Hot Streak in your heads up display. It shows the time remaining on both procs. When all of your fireblast charges are depleted the Heating Up proc will turn whitish grey instead of orange.
See Video.
Note: This WeakAura is meant to be used in conjunction with the default Blizzard procs that appear in your heads up display area around your character. These auras will overlay on top of the default Blizzard auras. Make sure and turn on the default Blizzard aura procs by hitting escape in-game, then navigate to interface > Spell Alert Opacity, drag the slider all the way to the right (High).
I use ElvUI with the UI Scale set to 0.71, you can navigate to this setting in ElvUI by going to General>General>UI Scale ( This may affect the image size and positioning of this weak aura).
If you're using default blizzard UI, you may have to adjust the size and positioning settings of this weak aura.
