How the Troglodyte Doll pieces work
Each doll fragment is a keepsake placed slightly off the main climbing routes. You are expected to notice unusual ledges, arches, and recessed platforms rather than follow the most obvious ascent line. Precision movement, piton placement, and short rappels are the intended tools here.
Once the third piece is collected, the Troglodyte Doll assembles itself in your backpack without any extra steps.
How to get the Troglodyte Doll piece in The Child
The first piece is hidden along The Child’s narrow black route, which is more cramped and technical than it initially appears. As you climb, watch the mountain face halfway up for tucked-away side ledges rather than continuing straight upward.
This section rewards slow scanning. Several players miss the piece by staying centered on the route, but the doll fragment sits just off to the side, often partially obscured by stone arches or shallow rock folds. Short piton placements followed by controlled traverses make this much safer than free climbing.
How to get the Troglodyte Doll piece in The Standing Stones
The Standing Stones piece is located behind an archway, branching away from the main climbing line. From the primary ascent, look for a path marked in green on the map that leads into a cave-like recess.

Instead of climbing down manually, anchor a piton and rappel into the cave area. Inside, you’ll find a ledge holding the second doll piece. Nearby camps make this a good place to save progress before attempting the descent.

How to get the Troglodyte Doll piece in The Vault
The final piece lies inside The Vault, but not along its main vertical shaft. You’ll need to explore inner rooms and side landings, especially recessed platforms that require short rappels or lateral climbs.

The doll fragment usually appears on a shelf or back landing that’s easy to overlook if you rush upward. Treat the Vault like a puzzle space rather than a straight climb, and scan every reachable ledge.

Using the assembled Troglodyte Doll
After collecting all three pieces, the Troglodyte Doll appears fully assembled in your keepsakes inventory. When activated during fog or storms, it instantly clears bad weather, restoring visibility and safer climbing conditions.
The doll has limited durability. Community testing consistently reports up to three uses total, so it’s best saved for sections where visibility severely impacts route planning.
Using the doll contributes toward unlocking the Meteorologist trophy or achievement.

Practical tips for finding all three pieces
Opening the local map or tab-view helps reveal keepsake markers you may have missed, especially near the troglodyte village mapping areas. When hunting pieces, prioritize pitons and short rappels over long descents to avoid unnecessary re-climbing and stamina drain.
Saving at nearby camps before committing to hidden routes also prevents losing progress if a narrow ledge doesn’t go where you expect.
Troglodyte Doll rewards
The Troglodyte Doll rewards curiosity and patience more than raw climbing skill. By stepping off the main routes in The Child, The Standing Stones, and The Vault, you gain one of Cairn’s most impactful tools for managing environmental danger—one that can turn a brutal storm into a clear, controlled ascent when you need it most.
