Cursed Surge Tracker

Cursed Surges rotate between five locations on The Coiled Isle every 45 minutes. The game will tell you where the current one is, but not where the next four are or when they land, so you end up alt-tabbing to a website, or opening the Events panel and doing arithmetic.

This puts all five on the map at once.

What you get

Open The Coiled Isle map and every spawn point has a venom droplet on it, wrapped in a radial timer ring:

• Green: spawning next. The ring drains as it approaches, with a countdown underneath.
• Orange: the one after. Same ring, same countdown, drawn smaller.
• Red: the remaining three. Nothing imminent, so no clutter.
• Cyan, pulsing: up on the map right now.

Orange and green share one continuous 90-minute countdown, so the ring empties exactly as the surge spawns. An empty ring always means now.

Left-click any pin to set a waypoint, using TomTom if you have it and Blizzard's own map pin otherwise. Right-click clears it. Hovering shows the rare's name, exact coordinates, and the start time in your local clock.

Warnings

A chat line and a sound at 5, 4, 3, 2 and 1 minutes before each surge, naming the spawn point and its coordinates. Log in partway through the countdown and it picks up from where you are instead of dumping every missed warning at once.

Warnings stay quiet in dungeons, raids, battlegrounds and arenas, so a key or a raid night isn't interrupted five times. Marks that pass while you're inside are consumed rather than queued, so walking out doesn't dump a backlog.

Configurable: /cs alert 10 5 1 to set your own marks, /cs sounds to audition the available alert sounds, /cs mute to change the instance behaviour, and /cs alert off to silence them entirely.

Accuracy

The schedule comes from C_EventScheduler, the same source as the in-game Event Schedule panel, and recalibrates on login and every five minutes. Rotation order and timing follow Blizzard's data rather than a hardcoded table, so a reshuffle won't break it.

The LIVE state is never inferred from the clock. A surge ends when its rare dies, often within minutes of spawning, so the cyan pin tracks the actual map vignette and disappears on the kill. Vignettes only load near the isle, so from far away a freshly spawned surge shows as LIVE with a tooltip saying it can't be confirmed, rather than pretending to know.

Notes

No dependencies. TomTom is used if present but is not required. MIT licensed. Fork it, fix it, keep it alive if I stop playing.
