How to get each sidearm
1. Nayleshotte
Prologue: Claimed with the starting equipment during the prologue.
2. Forgotten Crossbow
Flooded Village — Blackridge Pass: Break into the Flooded Village route, find the Damp Key after the lifts, and use it on the locked room containing the pickup.
3. Salvaged Trebuchaxe
Ravaged Hideout — Gloomshade Grove: Clear the hideout and inspect the body in its final room.
4. Troubadour's Lute
One Legged Wolf Tavern — One Legged Wolf: Enter the tavern and collect it from the stage; Gragu's Shell quest can be advanced on the same visit.
5. Triach Repeater
Blackwell Cavern — Castigator's Keep: Search the first illuminated room and the broken wagons on the floor.
6. Ballistazooka
Sentry's Grave — Gate of Mammon: Defeat the Subjugated Guardian miniboss in the dungeon.
7. Cursed Child
Revered Beacon dungeon — Sester's Gate: Reach the upper lighthouse section, break the central brazier, and collect the weapon before using the exit light.
8. Caged Hystrix
Chamber of Becoming — The Silent Steps: Complete Sariel's Chamber route and inspect the tablet near the dungeon exit.
If the achievement did not unlock
- Compare the inventory names against all eight rows, not only map markers you purchased from Merrick.
- Recheck the two late pickups: Cursed Child and Caged Hystrix.
- Confirm the Ballistazooka miniboss reward was actually collected after the fight.
- Make sure the Troubadour's Lute was picked up from the tavern stage rather than merely discovered on the map.
