How to get Triarch Repeater
- Fast travel to Castigator's Keep in Mammon.
- Drop into Blackwell Cavern beneath the Beacon.
- Search the first lit room and the broken wagons on the floor.
- The map to this gun can also appear as a one-way Crumbling Tunnel tablet near Proxima — that tablet is the map, not the Repeater itself.
When to use it
- High shot count. Enfeebling Stone maxes Fragile stacks quickly so melee hits harder.
- Balance Patch 1: no minimum Resolve to fire, same change as Caged Hystrix.
Before you leave
- Do not confuse the Fainweald Repeater map dungeon with this Mammon pickup.
All eight: Troubadour's Lute · Forgotten Crossbow · Nayleshotte · Salvaged Trebuchaxe · Ballistazooka · Cursed Child · Caged Hystrix.
