What are spur gears used for?
The spur gears are parts of mechanisms from the design of the Initial Ability Prototype No. 2, which stands in the middle of the hilichurl camp in the east of the Institute of Kinetic Energy. Previously, they were part of the figure of the Guardian of the Ruins, but were disconnected due to powerful external influences. Open the tab “Exercise” in the Inventory, where you will find each of the collected gears and you can check their type. In the guide we will show you where to use them to unlock the achievement. “Undocumented feature”.
Where to find Straight Gear C
Complete the puzzles and unlock the rich chests in the Hilichurl camp to get each of the gears. The largest tents visible on the minimap will serve as landmarks.
Gear C 1
The first Spur Gear C is in the treasury in the southeast of the camp. Defeat Hydro, Anemo rogue hilichurls and one regular one, after which cages with monsters will open.
Once you defeat the three Meks: Intelligence Protocols, access to the treasury will open. Go to the rich chest and get the Spur Gear C from it.
Gear C 2
Head to the northwest hilichurl building across from the shooting test. Destroy the enemies and break every vase – almost all of them will be inside the tent, and one is located to the left of the entrance to it.
When you destroy all the vases, interact with the rich chest and pick up the second Spur Gear C.
Where to Find Spur Gear T
The T Spur Gear is hidden in a rich chest located in the northeast of the camp, in a lower area.
Go to the smaller tent with the Pyro Void Mage – kill him and take the active energy storage device.
Follow the building with the treasury and destroy ordinary hilichurls along the way, which may prevent you from using items due to the battle mode.
Place the drive next to the Stabilizer and “Activate” his. Restore the device by hitting it when its ring is in the blue area.
When you hit the right moment, the area will change – repeat the steps until the mechanism restores stability. The order of lighting zones with blue light:
We recommend using characters with a one-handed weapon, spear or catalyst, as two-handed ones may be too slow to hit the stabilizer in time.
Once the device is in working order, the rich chest will be unlocked – get the Spur Gear T from it.
