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.

    Large issue with the swing module in 4.1. My FPS will drop tremendously and the game will often freeze up if I start to melee swing something with this module turned on.

    Turning it off fixes the problem but it'd be nice for this to work again.

    any plans to update to 4.1, as it seems a bit broken at the moment

    Try the alpha and see if that fixes your issue. It should solve any errors related to "profiles" or "bars resetting" or "RawHook".

    I committed the Drain Mana fix because it was trivial, and the chance of me doing it in a way you wouldn't like is basically zero. Hopefully!

    Any plan for the Boss frame casting bar? I can see them on the ShadowedUF but they are not customizable. Thanks.

    How would I go about adding an outline to the font on the Quartz cast bars? Thanks.

    EDIT: Found it: http://us.battle.net/wow/en/forum/topic/1869220436

    I'm having the same problem as ricks322. My red space for the latency is showing up at the beginning of the casting bar, and not the end like it used to.

    What's up with the Latency? It is showing at the begining of the bar, not at the end. I can find no way to change the location.

    This is from another user with the same problem:
    "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"

    I have a problem with the Latency instead to have it at the end like you can in the screenshot I get it at the begening of my casting bar .Someone can tell me if this a bug or how I can set it properly please?"
