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.

    Is there a posibility for adding an enemy swing timer? As far as I know, there is no posibility to get this information from the API, but I found a macro on curseforge that returns the targets attack speed to the chat window. It should be posible to start a timer of that value after a hit occures, shoudn't it?

    I already tried to work this out myself, but without even the slightest bit of lua knowledge this is a task, nearly impossible ;). I know, btw, that there is an addon for this task (called BossSwingTimer), but afaik it has no config and isn't lockable.

    Here is the macro I found: /script mainSpeed, offSpeed = UnitAttackSpeed("target"); DEFAULT_CHAT_FRAME:AddMessage("Main Hand: "..mainSpeed); DEFAULT_CHAT_FRAME:AddMessage("Off-Hand: "..offSpeed);

    Not sure where else to go for help, but buff bars don't seem to be functioning for me right now. Anyplace I can go to troubleshoot this?

    Hi, Any chance you could update this also on Curse? Thanks

    I think the breath guage has been separated from the Mirror bar. I have Mirror enabled but when I go underwater, I get the default Blizz bar. (unless I'm missing a setting somewhere) It wasn't doing that before 5.0.4. :)

    I spent a few hours today and edited the default 3.0.6 release to accurately show DoT ticks, even extra ones from haste and haste procs / raid buffs. It also updates the tick positions after spell push back.

    I was wondering if the authors wanted to look at the code and integrate it with their official release. Let me know.

    Hi, great addon!

    I have been wanting a cast time indicator on the buff bars for some time.. Tonight I finally sat down and hacked it in;

    This is the code I inserted, on line 955 of modules/Buff.lua

    if not bar.castTimeIndicator then
    	bar.castTimeIndicator = bar:CreateTexture(nil, "OVERLAY")
    _, _, _, _, _, _, castTime = GetSpellInfo(v.name)
    if castTime then
    	local w = (castTime / 1000) * bar:GetWidth() / (endTime - startTime)
    	bar.castTimeIndicator:SetPoint("TOPLEFT", bar, "TOPLEFT", w, 0)
    	bar.castTimeIndicator:SetPoint("BOTTOMRIGHT", bar, "BOTTOMLEFT", w + 1, 0)

    This appears to work perfectly for me, but it might break for others.. Only tested it using my shadow priest.

    Cheers, Pres

    Is there a Quartz module or feature aimed at helping the player always get their next cast fired off within the 0.5 second next cast buffer? I'm thinking something similar to the red/colored portion of the cast bar used to indicate latency. I'd be interested in this functionality both for the main player cast bar as well as the GCD spark.

    I know the exact time is already displayed, but that's not quite as easy to use as a big colored bar. I also know many players (including me) have a rhythm that probably already works most of the time, but I do feel like I miss the buffer every once in a while, particularly during haste procs where I'm casting a string of instants.
