Doloc Town Environmental Modifier Guide – Small Battery, Wire Puzzle & Repair
Where to find the Environmental Modifier in Doloc Town, the 2 Small Batteries and 5 Electric Wires needed for the repair, and the Phase 1 flow.
The Environmental Modifier is the River Valley story gate: a broken machine you repair to open the main story route to Treaty Port. You need 2 placeable Small Batteries and 5 Electric Wires, plus a Core Sample taken from the Core Extractor.
One detail trips up most players: a normal Battery does not work here. The quest requires the placeable Small Battery item, which is crafted separately. The 1.00.02 patch added new Environmental Modifier parts, so Early Access material below is labeled where it is used.
Quick Answer: What Is the Environmental Modifier?
The Environmental Modifier is a story-gate machine in River Valley that Mody needs repaired. Fixing the damaged circuit and activating Phase 1 opens the waterway to Treaty Port so the main story can continue. It is not a craftable item: it is a location-based repair objective.
Where to Find the Environmental Modifier
The machine is in the River Valley region, past the Town area. Community reports from Early Access describe the route: from the farm, go down, then left, then up, into a cave that used to be blocked by a landslide. A small pond and trampoline sat in front of the entrance, and clearing the entrance required story progress.
The cave route above comes from a Steam community thread from May 2025. Version 1.00.02 added new Environmental Modifier parts and changed energy gain, so the exact path may differ in the current build. Check the quest marker instead of relying on the old map notes.
Materials: 2 Small Batteries + 5 Electric Wires
The repair needs two placeable Small Batteries and five Electric Wires. The critical detail is the word Small.
- 2× Small Battery — the placeable small-battery item (base equipment), not the regular Battery item.
- 5× Electric Wire — the same wires used for generators and other powered machines.
- Small Battery may appear unavailable until the tech node is unlocked.
Small Battery Recipe and Unlock
- Recipe: 2 Copper Ingot + 2 Rubber + 1 Battery = 1 Small Battery (current recipe database, matched by the published August 2026 guide).
- For two batteries: 4 Copper Ingot + 4 Rubber + 2 Battery.
- If the recipe is missing, unlock Industrial – Basic Power Storage in the tech tree.
This is why some players arrive with fully charged normal batteries and still fail: they have the right power, but the wrong item.
How to Repair the Environmental Modifier (Step by Step)
- Reach the Core Extractor and take a Core Sample.
- Travel to the Environmental Modifier in River Valley.
- Check the damaged circuit on the panel behind the machine.
- Prepare 2 Small Batteries.
- Prepare 5 Electric Wires.
- Repair the damaged circuit with the batteries and wires.
- Insert the Core Sample into the machine.
- Charge the machine to 30 Energy.
- Activate Phase 1.
- The waterway to Treaty Port opens; the main story continues there.
- Later Environmental Modifier phases continue in the late game.
Two common mistakes: bringing regular Batteries instead of Small Batteries, and leaving after the circuit repair without inserting the Core Sample and activating Phase 1.
How to Solve the Wire Puzzle
The exact wire sequence is not confirmed in the current research. Early Access players reported that the clue in Encyclopedia > Archives — a guide left by Mody — does not match the quest and contains a twist, and a 2025 solution video exists, but no current source repeats a complete valid sequence for 1.00.02. Until the sequence is verified in gameplay, treat any specific ordering as unconfirmed; the repair itself only requires the 2 Small Batteries and 5 Electric Wires.
No source verified against version 1.00.02 currently lists the complete correct wire order. This section will be updated as soon as the sequence is confirmed in gameplay.
What Happens After Phase 1
Activating Phase 1 clears the River Valley blockage, the story moves back to Treaty Port, and later the Wetlands and later regions open. Published guides describe further Environmental Modifier phases as late-game content.
FAQ
- What batteries do I need for the Environmental Modifier? Two placeable Small Batteries. A normal Battery is not a substitute.
- How many Electric Wires do I need? Five.
- Why doesn't a normal Battery work? The quest checks for the placeable Small Battery item; sources state that the word "Small" is the important detail.
- What happens after Phase 1? The route to Treaty Port opens and the main story continues there. Later phases of the modifier are late-game content.
