When you try to use an ability that is on cooldown the aura will show the remaining cooldown of that ability.
It also takes GCD and the last used spell into account. This prevents the aura from being shown immediately after using an ability with a cooldown when spamming the button. (This behaviour can be turned of in the custom options). Only after the GCD is over the spammed ability will be shown as on cooldown. This can be seen in action in the screenshot gif.
Adjust display and animation settings to your liking.
Custom options:
- Ignore GCD: Toggle the GCD behaviour as described above.
- Display duration: How long the aura is displayed (in seconds).
Note: When the ability finishes it's cooldown during the display duration the aura gets hidden
