The Janthir Wilds expansion gave Guild Wars 2 a new open-world meta worth farming. “Of Mists and Monsters” runs in the Janthir Syntri map and asks the whole zone to split its forces between two legendary titans — Decima to the north and Greer to the south — and kill them within 30 seconds of one another. It repeats every two hours, pays out loot on both sides, and is one of the more reliable gold-per-hour loops the expansion added. Here is how the loop works, what each half pays, and how to run it efficiently.

What changed

Of Mists and Monsters shipped with the Janthir Wilds expansion and lives entirely in the Janthir Syntri zone (level 80). Per the official Guild Wars 2 Wiki, the meta is built around a single rule: two legendary enemies spawn in different locations, and both must die roughly at the same time. If one falls and the other survives past a 30-second window, the defeated titan revives at 10% health and the fight continues. The wiki and the zone’s event timers confirm the cadence: the meta begins at the xx:40 mark of each two-hour cycle, with a limited active window to bring both titans down (community timer sites report about 15 minutes).

The two bosses sit at opposite ends of the map:

  • Decima, the Stormsinger spawns in the north, around the Kindle Barrens near the Stricken Plains waypoint. She deals Power damage — avoidable red telegraphs, electrical conduit lines, and an arena-wide shock at low health.
  • Greer, the Blightbringer spawns in the south at The Infested Quag near the Festering Basin waypoint. He deals Condition damage — heavy poison application, boon corruption, and thorn shields that block projectiles.

Each boss has the same phase structure: a normal damage phase, a defiance-bar phase at 75% and again at 25% that must be broken with crowd control, a mounted Warclaw chain-pull sequence that strips the boss’s armor, and a final burn phase where the boss stops attacking and charges an ultimate.

How it works

The twin-kill rule

The core mechanic is the synchronized kill. The wiki walkthrough states it plainly: there is a 30-second timer between the two deaths. Kill Decima first and you have 30 seconds to finish Greer, or Decima respawns at 10% and you repeat the north fight. The practical consequence is that squads split into two roughly even groups, each tagged by a commander or mentor icon for stacking, and the two halves communicate kill speed so neither side pushes ahead.

The standard approach is to let the faster side hold at 75% and 25% so the slower side can catch up. South (Greer) generally moves faster early because his add phase at 75% can be rushed, while north (Decima) has more positioning demands from the conduit-line mechanic. Commanders typically call “hold at 25%” to sync the final burn.

The Warclaw phase

At 75% and 25% each boss goes immune, spawns a defiance bar, and — once the bar is broken — forces every player onto their Warclaw mount. Chains auto-fire at the boss (unless you were facing the wrong way, in which case you attach manually), and players must ride counterclockwise through checkpoint gates ringing the boss. Each gate tears off a piece of armor; clearing all of them drops the boss to the ground and resumes the normal fight.

Greer’s 75% phase adds a wrinkle: seven titanspawn adds spawn and must be cleared before his breakbar appears, and the adds can run, which is the main reason south sometimes falls behind. Decima’s 75% phase instead requires breaking six stacks of Flux Shield, each tied to a conduit that, if left charged, explodes for heavy damage when the phase ends.

The green-and-red mechanic

Throughout both fights a “green” marker appears that demands player stacking. On Greer, green circles spawn under one or two players and need at least three people stacked on each — do not carry them out of the group. On Decima, green lines connect her to her conduits and need at least three players standing in each line to stop her gaining an “Empowered” buff. Red lines, by contrast, kill anyone standing in them — let those through. The general rule: stand on green, avoid red and purple, and bring condition cleanse for Greer’s poison and boon corruption.

Build path

The rotation

A single two-hour loop in Janthir Syntri looks like this, anchored on the meta timer:

  1. Pre-meta (xx:30–xx:40): The wiki notes a 10-minute pre-start window where the kodan announce the approaching storm. Use this to run the other Janthir Syntri events that are force-stopped once the meta begins — chiefly the renown hearts (helping the kodan settle, researching the titan blight), the relic hunts in the central area, and the northeast lightning-rod and debris-collection chains. These pay standard event rewards and contribute to map participation.
  2. Meta start (xx:40): Move to your assigned side. North groups gather at Stricken Plains waypoint and walk south to Kindle Barrens; south groups gather at Festering Basin waypoint. Split roughly 50/50, with a slight lean to south if your map is heavy on condition-cleanse builds.
  3. Boss fight (xx:40–xx:55): Push to 75%, break defiance, run the Warclaw gates, repeat at 25%, then burn to the synchronized kill. Loot both boss chests — you can collect from both sides if you tag both bosses, but you must be present when each dies.
  4. Post-meta: The map goes quiet for roughly an hour and fifty minutes. Use the gap to hop to Mistburned Barrens (the second Janthir map, added in the Repentance update), whose own meta — Discovering Mistburned Barrens — runs three survey lanes (Valley of Agony, Wraith’s Pass, The Blood Phenom’s Corridor) that can be cleared in the off-window, or to map-completion and mastery-point hunting.

Maximizing gold per hour

The meta pays out in unidentified gear, champion bags, and the meta bonus chest, plus side-specific chests: Decima’s side guarantees Charged Titan Ore, while Greer’s side guarantees Rotted Titan Amber. Because you can earn credit on both bosses if you tag each one and are present at its death, the optimal loop has you start on one side, hit the boss a few times, then waypoint to the other side before it dies — but only if your map’s population is high enough that neither side fails without you. Keep in mind that the Hero’s Choice Chest and Magnificent Chest are once per day per account, while the side chests require you to be present when that titan falls. On a full map, staying put and maxing participation on one side is usually more reliable than splitting for double loot.

Three things push gold per hour up:

  • Map participation cap: Stay for the full event chain so your participation bar hits gold. Leaving early forfeits the bonus chest.
  • Magic Find: The Janthir maps drop a lot of unidentified gear; higher Magic Find converts more of it to exotic/rare salvage fodder. Stack consumables during the meta window.
  • Mistburned Barrens alt-meta: Running the survey lanes in the off-hour keeps your event cadence high instead of idling, which is the single biggest determinant of gold per hour in open-world farming.

What it means

Of Mists and Monsters is the kind of meta that rewards map awareness over raw DPS. The twin-kill rule forces coordination, the Warclaw phases reward crowd-control builds, and the two-hour cadence makes it predictable enough to schedule around. For players who came to Janthir Wilds for the Warclaw mount and the kodan story, the meta is also one of the expansion’s main repeatable income sources — a clean loop that, paired with Mistburned Barrens in the off-window, keeps the Janthir region productive between major content drops.
