Target Marker Assistant is a World of Warcraft addon built around target marking and combat communication. It is aimed at dungeons, Mythic+ runs, and raids — the kinds of group content where focus targets, interrupt assignments, and priority mobs need to be called quickly and clearly.
The main workflow is a custom key binding plus a mouse click. Click a target with the key bound, and the addon can set that target as focus and apply a raid marker. After the mark lands, it can send a configurable message to a chosen chat channel. That makes it easier to split interrupt duties, call a kill target, or flag a dangerous mob before the pull gets messy.
It also includes interrupt barrage notifications and a sound cue that plays when a marked target begins casting an interruptible spell. These cues are meant to give the group a clearer read on which cast matters and when to react. Used alongside a nameplate addon with target coloring, the marked target is easier to pick out from a pack, so interrupt assignments and priority damage can be handled faster.
Current version v1.1.3 is a maintenance release: several known bugs were fixed.
The v1.1.x line has mostly focused on interrupt monitoring and notification reliability. In v1.1.2, cooldown prompts were expanded beyond the main interrupt to cover auxiliary interrupts, cast stops, and racial control abilities such as Dragon's Breath and Tail Swipe; this gives players another option when their main interrupt is down. That update also fixed a Mythic+ bug where the interrupt cooldown monitor could not read the monitored skill's cooldown.
v1.1.1 added the interrupt cooldown prompt itself: when a monitored interrupt comes off cooldown, a cooldown ready message appears near the top of the screen so the player can prepare the next interrupt. It also included fixes for known bugs.
v1.1.0 was a larger rebuild. Because Blizzard's API policy changes can cause spell IDs, target IDs, and other dynamic information to return encrypted values in restricted content such as Mythic+, and because chat output is more tightly limited, the interrupt monitoring and notification logic was reworked. This version added onscreen barrage notifications for interrupt results when chat is unavailable or restricted, reducing reliance on chat channels. It also added drag-and-drop focus interrupt macros: the currently monitored skill can be dragged to an action bar to generate a focus interrupt macro automatically. The addon was adapted to WoW 12.0.5's chat and protected-value restrictions, and the settings panel opening logic was adjusted to avoid opening it during combat and reduce protected UI errors.
Earlier fixes: v1.0.3 and v1.0.2 addressed known issues. v1.0.1 fixed a bug that prevented interrupt text notifications from appearing in Mythic+ dungeons. It also added multiple notification voices — Arthas, Brann Bronzebeard, Illidan, Sylvanas, Xal'atath, Anduin, Millhouse, and murloc — plus a separate skill configuration panel, still opened with /mb. The combat notification skill monitoring was also changed to use custom skills rather than the class/spec default interrupt.
The original v1.0.0 feature set included quick focus setting and raid marking; custom key binding plus mouse click marking; automatic chat callouts after marking; configurable callout text and channel; automatic interrupt notifications (since the old combat log API is no longer available, the addon cannot confirm whether an interrupt succeeded, but it announces when an interrupt action starts, e.g. I've used [Counterspell], 30 seconds cooldown remaining); a sound when a marked target casts an interruptible spell; a minimap shortcut and /mb command for settings; and support for Simplified Chinese, Traditional Chinese, and English.
