Quartz
Quartz is a modular approach to a casting bar addon. An overview of (hopefully most of) the modules:
*Player
The core of Quartz is lightweight implementation of a standard casting bar, with configurable size, text and icon positioning, and colors.
*Target/Focus
Implementation of target and focus casting bars in similar fashion to the player cast bar.
*Buffs
Display of target and focus buffs and debuffs as duration bars.
*Flight
Hooks into FlightMap or InFlight to display the current flight progress on your casting bar.
*Global Cooldown
Displays a tiny spark-bar to show your Global Cooldown near the cast bar. Helpful for those who'd rather not squint at their action bars to see when they can cast again.
*Interrupt
Changes the color and text of your casting bar to help show that your cast has been interrupted (and show who interrupted it).
*Latency
Displays the amount of time spent between cast send and start events, in the form of a bar at the end of your casting bar, with optional text that displays the actual duration of the lag. This helps in canceling casts when they will not actually be interrupted, especially for users with consistently high pings.
*Mirror
Shows the 'basic' timers such as breath and feign death, as well as some 'odd' ones such as party invite time, resurrect timeout, and arena game start, and a framework for injecting custom timers into the bars.
*Range
Recolors the casting bar when your cast target moves out of range mid-cast.
*Swing
Displays a swing timer for your melee weapon as well as hunter autoshot.
*Timer
Allows for creating custom timers displayed on the mirror bars.
*Tradeskill Merge
Merges multiple casts of the same tradeskill item into one big cast bar.
Use /quartz to bring up the configuration menu.

Posted Feb 6, 2026Will there be an update / a new version of Quartz for midnight? I've been using it for many years and I really don't wanna try any of the new cast bars people try to make right now. Quartz was always awesome right out of the box.

Posted Jan 27, 2026Have been using Quartz for a decade or so. Really sad to not see it getting any updates for Midnight. Tried other castbar addons.. none of them is really good, lot of bugs, etc. Any news regarding an update for Midnight?

Posted Jan 28, 2026In reply to Fistao: I'm not the author nor do I have extensive experience with WoW AddOns (a little here and there) but I did get it to work to a limited extent. Non-player castbars work with a basic duration text display. I did get it to change the bar border when a spell is interruptible but dynamically changing the color is proving difficult because the frame is getting tainted at some point and wont accept secret values anymore. (And I'm not really sure how to track down why.)
Part of that was completely replacing the custom statusbar frame with the default one since custom frames can't accept secret values.
Fortunately, the player casts seem to be non-secret even during combat so the player castbar is largely functional.
At the end of the day an updated Quartz is likely going to require a major rewrite and some features may not be possible.
I'm not really sure if sharing my modified copy is 'okay'. The changes are more extensive than a quick 'swap this with this' fix.

Posted Jan 28, 2026Well, I guess the code is GPL so nothing is stopping me from creating a fork. But I'm not sure I'm ready to do more than some 'quick' fixes.

Posted Jan 26, 2026Going to be brutally honest, while I can get it to a state of mostly working with minimal LUA errors (though not none) there are a number of features that relied on being able to access values which are now considered 'secret' when in combat.
Anything that's not just passing a value through to a display element will probably not be possible in combat scenarios.
