An Unidentified Molepig Den, one of the possible sample nodes.
The Three Brothers
Unidentified Samples are a unique Gathering mechanic in The Three Brothers DLC, in the Caldera region.
Overview[ | ]
There are three types of Unidentified Sample nodes you can find in the Caldera region:
- Unidentified Molepig den (produces Molepig Specimen, requires Fishing Harpoon)
- Unidentified Ore Vein (produces Ore Sample, requires Mining Pick)
- Unidentified Roots (produces Plant Sample, requires Mining Pick)
There are many potential locations where these nodes spawn, and there are four random rotations which determine which nodes will be active at any one time.
The random rotation changes every two in-game days, however the samples themselves are subject to Area Reset and still require 7 days spent outside of the scene to replenish their resource. A quick way to reset scenes is by speaking to Josef Dumas and offering to help build for a week.
In addition to the random rotations, all nodes have 10 random positions (for exterior nodes) or 5 random positions (for dungeon nodes) where they may spawn. This means that realistically you will have a rough idea at best of where you should expect to find them, but over time you will become familiar with common places to look.
Identifying[ | ]
Samples can be identified by Evangeline Vallier in New Sirocco after the Sirocco quest line has begun.
You have an equal chance of receiving any of the available 6 outcomes from each sample.
Expeditions[ | ]
(Definitive addition only) After your first 3 samples handed into Evangeline, and then every 10 samples after that, players can ask her to send out workers on an expedition to hunt for a specific rare material. It takes 24 in-game hours for the expedition to complete, after which the player will receive the material for free, and can then send out another expedition if they wish (after another 10 samples have been handed in).
Rotations[ | ]
There are four random rotations which determine where the nodes will spawn, and the rotation will change every 2 days - though it is possible to get the same rotation twice in a row.
The maps for the exterior regions show the potential spawns for each rotation, but keep in mind only one of each ID (the number) for each node can be active at a time.
