ComboGlow
World of Warcraft combat moves fast, and the difference between a good rotation and a great one often comes down to how quickly you notice that a proc is ready or a debuff has fallen off. ComboGlow solves this by lighting up your action bar buttons based on three distinct states: your aura is active, your aura is missing, or your spell is ready to fire thanks to a resource threshold or a proc. It is a focused, no-nonsense addon built for players who want visual clarity without drowning in configuration menus.
What ComboGlow Does for Your Rotation
Every spell that spends your class resource gets a rule automatically. Combo points, holy power, chi, soul shards, arcane charges, essence, and more are all covered. The addon scans your bars the first time you log in on a specialization and prints what it added to chat. No hardcoded spell IDs, no per-class tables, so nothing rots across patches. Fixed-cost spells become "at least this much" thresholds, while variable-cost finishers light up at maximum resource.
Three States, Three Visual Cues
- Up: your aura is on the unit, shown with green marching dashes.
- Gone: the aura is missing, displayed as a red colour wash.
- Ready / Proc: resource threshold met or spell procced, marked with a gold glow.
The reminder strip sits above your class resource bar. Every "gone" state places its icon there while the aura is missing, so what needs pressing is right next to the resource you are already watching. This keeps your eyes where they belong: on your resources, not scanning the entire action bar for a missing glow.
How to Install ComboGlow
Installing the addon takes less than a minute. Download ComboGlow, extract the folder into your World of Warcraft/_retail_/Interface/AddOns directory, and restart the client. The addon is a standalone folder, so other UI suites cannot overwrite it. If you use the EllesmereUI suite, ComboGlow automatically borrows its glow engine so the animated markers match the rest of your interface. For players looking to download ComboGlow quickly, the foxygame.net launcher offers a one-click install that places the addon in the correct folder and handles version compatibility automatically, so you never have to worry about manual extraction again.
ComboGlow for World of Warcraft: Version Support
ComboGlow is built for the latest Retail version, specifically 12.1 (Midnight), where the aura APIs are largely closed to addons. It uses only targeted queries like C_UnitAuras.GetAuraDataBySpellName and GetAuraDuration, avoiding the iteration methods that break under Midnight's restrictions. The addon also supports Classic, TBC, WotLK, Cataclysm, and MoP versions, making it a versatile choice for players across all official game modes. For those managing multiple clients, the foxygame.net launcher includes ComboGlow in its addon catalog and keeps it updated across Retail and Classic folders, which is a real time-saver when you play several versions of the game.
Setting Up Your First Rules
There is nothing to configure at first. Log in, and ComboGlow scans your bars and creates rules for every spell that spends your class resource. Open the options window with /cg. Pick a spell on the left, a state on top, then click a marker. That click also creates the state, so setting one up is a single click. The list shows one row per spell with three pips on the right, green, red, and gold, lit for the states that are set up.
Live Preview Gallery
The gallery above the list switches which state you are editing, and every tile is a live preview: a real overlay running the same code as the bar, drawn on that spell's own icon. Six marker styles are available: solid, fill, active, pixel, shine, and modern. A few extra styles like button, gcd, and classic remain available through /cg style but are kept out of the gallery because they look identical once tinted.
Handling Complex Aura Cases
Some spells apply another spell's debuff. Primal Wrath puts Rip on everything, so its button has no aura of its own. ComboGlow detects this automatically: for a spell the Cooldown Manager does not track as an aura, its own description is searched for the name of one that is. The game already says "applying Rip", so there is nothing to look up. One match is taken and announced in chat; anything ambiguous is left for you to point by hand through the watching row.
Count Formats and Warning Thresholds
Count formats are flexible. Write 5 or 5+ for five or more, =5 for exactly five, 3-4 for a range, and max for the current maximum, which follows talents that raise the cap. A few seconds before an aura runs out, the frame turns red. Use /cg warn <number> <seconds>, with 4 seconds by default and 0 to disable. The threshold works even when the duration is secret, baked into a step colour curve the engine evaluates.
Commands and Compatibility
ComboGlow works with Blizzard's own action bars, Dominos, and anything built on LibActionButton-1.0 like Bartender4 or ElvUI. Macros are parsed down to the spell they cast, including base spells and overrides from forms, talents, and replacing IDs. The addon only reads UnitPower and draws frames; it never casts or clicks for you, just pure UI code. For players who want to download ComboGlow alongside other UI addons, the foxygame.net launcher's auto-update feature ensures ComboGlow stays current with each game patch, so you are not left hunting for manual downloads after a Tuesday reset.
Useful Slash Commands
/cgor/cglor/cglowor/comboglow: open the options window./cg help: command list./cg preset: scan the bars and set up what it finds./cg clear: remove every rule of this spec./cg list: list the rules with data source and button count./cg move: drag the reminder strip elsewhere./cg centeroff: turn the reminder strip off./cg auracheck: print what the API actually returns where you stand.
ComboGlow is a practical, lightweight solution for players who want their rotation feedback front and center. It respects the new API restrictions, works across multiple game versions, and requires zero setup to deliver immediate value. Whether you are a Feral druid tracking Rip or a Holy paladin managing holy power, ComboGlow puts the information you need exactly where you are already looking.
