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 Jan 17, 2026In reply to stenstureog: The fix is "easy". You have to add a few lines in the Config.lua from line 195 to line 206.
Alternative you can download and replace it with my lua file. Or download the version @kazso mentioned.

Posted Jan 15, 2026Hello. I know it's probably not a priority, but is there a chance to fix it for TBC anniversary?
Specifically, crafting multiple items does not work properly (castbar shows wrong info).

Posted Jan 10, 2026In reply to doohan111: There is a complicated answer to this, but because of limitations on how classic event handling works, the game api does not properly fire the SpellCast start event for multishot or aimed shot. As a work around, Quartz implements LibClassicCasterino.lua which handles this issue by reading the combat log for the spell name and displaying the bar when found. However, the way it it implemented, they only added the max rank (6) of aimed shot, and thus and other ranks will not display. You can fix this by locating the following in file World of Warcraft\_classic_era_\Interface\AddOns\Quartz\libs\LibClassicCasterino\LibClassicCasterino.lua: [20904] = 3, -- Aimed Shot. 20904 is the max rank for aimed shot in classic (6). if you replace that line with the following and /reload it should work.
[19434] = 3, -- Aimed Shot (rank 1)
[20900] = 3, -- Aimed Shot (rank 2)
[20901] = 3, -- Aimed Shot (rank 3)
[20902] = 3, -- Aimed Shot (rank 4)
[20903] = 3, -- Aimed Shot (rank 5)
[20904] = 3, -- Aimed Shot (rank 6)
Note: This is assuming that there are not any other addons using LibClassicCasterino, as if they are, it may/may not load the modified version but instead load a different version that doesn't contain your changes.

Posted Dec 30, 2025Hi I just have added your addon to my collection I really like all the options you have added so I can customize it all. For me I like to have a real basic looking cast bar, its just a bar with now border or smooth edges. The only thing is when I cast Sinister Strike or any other ability it shows a little part of an glowing bar? and when I use my Hearthstone it shows the text 118ms, have I missed something in the options menu? because I really would like to change that.
Already thanks a lot this lovely addon

Posted Dec 23, 2025Won't show the cast time of Aimed shot as hunter.
Any1 else having the same problem ? (playing on anniversary servers)
EDIT: Actually noticed that sometimes the addon glitches itself and it does have a cast bar of Aimed shot, but thats once in every blue moon ? could it be that there is another addon interfering or is it something else.

Posted Dec 19, 2025There are new API changes that should allow this addon to work. Will it still be a thing? Or is the rewrite too much?
