About this addon
What it does
ClassicCastbars
Customizable castbars for Classic WoW. Type "/castbar" to open the options panel.
Includes optional party & nameplate castbars, school lockout alerts, and basic channel + uninterruptible cast state tracking for Classic Era.
Midnight Update
Retail is now currently unsupported until I get the time to look at the new API changes.
Classic Era 1.15.0+
This addon is no longer needed for Classic Era to see target castbars. You may safely disable this addon now and enable castbars in Blizzard Options -> Interface -> Show Enemy Cast Bar instead.
For anyone still using it for castbar customizations, make sure you're using version 1.7.2+ to support the new built in cast events.
I no longer actively play, so uninterruptible cast state tracking (grey border shield) is not updated for latest Season of Discovery spells.
