Quartz is a modular approach to a casting bar addon. An overview of (hopefully most of) the modules:


The core of Quartz is lightweight implementation of a standard casting bar, with configurable size, text and icon positioning, and colors.


Implementation of target and focus casting bars in similar fashion to the player cast bar.


Display of target and focus buffs and debuffs as duration bars using the new API introduced in patch 2.1.


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.


Changes the color and text of your casting bar to help show that your cast has been interrupted (and show who interrupted it).


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.


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.


Recolors the casting bar when your cast target moves out of range mid-cast.


Displays a swing timer for your melee weapon as well as hunter autoshot.


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.

    When swimming there is an air bar in the default ui. I see no such bar with quartz and have drowned several time due to not being able to see it.

    Hello. I use eepanel2 to create the artwork for my UI and I would love to be able to attach some art to the "Mirror" bar, but for the life of me I cannot figure out what it's called ingame so I can attach the art to it. If anyone knows and could tell me that would be great. By the way I used /print GetMouseFocus():GetName() in game to get the window name but it just says nil. Thanks. Love the mod.

    Having an issue where it will pop up a swing timer at random intervals for absolutely no reason. It won't even be a relevant swing timer. For example, my rogue which uses 1.8 and 1.4 speed weapons will randomly get 2.2 second swing timers to count down a bunch of times.

    This is on r8.

    hi not sure if you are aware but the warrior move slam doesn't reset your swing timer anymore but the version of quartz i've got r7 (can't dl r8 yet) still resets the swing timer. This makes the swing timer go out of sink and its pretty much useless
