Arc Raiders Mushroom Farming Guide

Mushrooms are one of the trickiest but most important resources in Arc Raiders. You need a surprising number of them to fully upgrade Scrappy the mechanical rooster back in Speranza, and they don’t stand out as clearly as metal scrap or other loot. This guide walks you through the best spots to find mushrooms, how to structure your farming runs, and how to use events and map knowledge to make the grind far more efficient.

Why Mushrooms Matter in Arc Raiders

Before planning your routes, it helps to understand what mushrooms are used for and why they feel so scarce.

• Scrappy’s final upgrade: The fifth (max) upgrade of Scrappy requires a large batch of mushrooms along with other ingredients. Expect to gather double-digit amounts of fungi before you are done.
• Nature resource type: Mushrooms belong to the Nature category of materials. That means they tend to appear in damp, overgrown environments—think trees, mossy areas, and interior garden spaces.
• Shared spawn logic: Mushrooms follow the same general spawn logic as other natural collectibles, so understanding their ecosystem helps you track other rare plants too.

Because of these factors, mushrooms often feel like a bottleneck resource. You will likely hit a point where Scrappy is waiting on fungi while you’re drowning in metal and other scrap.

Core Mushroom Spawn Principles

Even though exact spawn points can be random, mushrooms tend to follow a pattern. If you keep a few rules in mind, you can spot them more consistently.

• Look for trees and deep foliage: Mushrooms most frequently appear on or around trees. Pay attention to tree trunks, especially in areas with dense undergrowth.
• Seek out damp, shaded spots: Swampy terrain, shaded forest patches, and moisture-heavy facilities such as hydroponic domes are prime mushroom territory.
• Check nature-focused POIs: Points of interest flagged as having vegetation or water features usually offer better spawn odds.
• Use events to your advantage: Under certain map conditions—particularly those boosting nature spawns—mushrooms appear more frequently in the same zones.

This general logic holds true across all maps. What changes is how compact or spread out the good zones are, and how dangerous they are to traverse.

Best Mushroom Maps: Dam Battlegrounds and Spaceport

Mushrooms can appear on more than one map, but two areas stand out as the most reliable sources:

• Dam Battlegrounds – a lush, spread-out region with multiple nature-heavy zones.
• Spaceport – more industrial overall, but with a remarkably dense tree cluster that spawns mushrooms regularly.

Below is an overview of how these maps compare for mushroom farming:

Dam Battlegrounds: High-Yield Mushroom Routes

Dam Battlegrounds is renowned as the best overall mushroom map because its nature POIs are both numerous and densely packed. If you have time for a longer raid, this is where you’ll want to go.

1. Hydroponic Dome Complex and Surrounding Forest

The Hydroponic Dome Complex is a stand-out hotspot. It’s essentially a greenhouse facility with lots of vegetation both inside and just outside the structure.

Key tips for this route:

• Check interior planters: Inside the domes you will find planter beds and small containers with plants. These are common mushroom spawn locations.
• Scan trees around the complex: Once you exit the domes, shift focus to nearby trees. Trunks near the riverbanks can hide multiple fungi.
• Stick to loops, not straight lines: Instead of walking in a straight path, loop around the complex and the tree line to catch multiple potential spawn clusters.

This region is fairly large, so expect to spend a decent portion of your raid on foot. The upside is that a single lap here often yields several mushrooms, especially under favorable map conditions.

2. Riverside and Adjacent Woodland

Beyond the dome, the river corridor running through Dam Battlegrounds offers extra mushroom spawns. Trees along the water’s edge are particularly good targets.

• Follow the river bends: Many tree clusters sit along bends in the river. Move from cluster to cluster, scanning trunks and roots.
• Use cover wisely: The river valley can be exposed to enemy patrols and other players. Move from cover to cover to avoid getting caught out while staring at tree bark.
• Plan your extraction: Since mushrooms are relatively light but valuable, aim to hit a nearby lift after a successful loop instead of overextending.

This stretch is a strong complement to the Hydroponic Dome route. Start in the dome, then follow the river until you’re near a safe extraction point.

3. Water Treatment Control Pipes

The Water Treatment Control facility is more compact but includes a lesser-known mushroom spawn type: fungi appearing on or near the pipes on the upper floors.

• Small search area: Unlike the forests, this is a relatively tight space, so you won’t need to wander far.
• Random spawn variance: Mushrooms are not guaranteed here every raid, but the run is short enough that it’s still worth a quick check.
• Vertical awareness: Scan along railings and pipe surfaces above you; mushrooms can blend into the environment easily.

Because the area is compact and risky, it works best as a supplemental stop on your Dam Battlegrounds route rather than a primary farming zone.

Spaceport: Fast Mushroom Runs Between Industrial POIs

Spaceport looks like a hostile industrial zone at first, but it offers one of the most efficient mushroom runs in the game thanks to a dense cluster of trees in a relatively small area.

1. Tree Cluster Near Little Hangar

Between Little Hangar and a nearby container yard sits a miniature forest patch. Despite not being flagged as a nature POI, this small grove is a reliable mushroom source.

Here is how to handle the run:

• Identify the forest pocket: On the Spaceport map, look for the green patch between Little Hangar and the container zone to its east. That clump of trees is your main target.
• Circle the trees slowly: Walk around the entire grove, scanning tree trunks and the bases where the ground vegetation is thickest.
• Repeatable route: Because the area is so small, you can get in, grab your mushrooms, stash them safely, and then either extract or reset your run for another attempt.

This spot is especially useful if you only have time for short raids or if you want to stockpile mushrooms using a fast, low-risk loop.

2. Secondary Tree Pockets and Structures

While the main tree cluster is the star of the show, it’s worth checking a few nearby structures and smaller green pockets.

• Perimeter trees: Trees just outside the main cluster can also spawn mushrooms, so don’t limit yourself to the densest area.
• Edges of industrial buildings: Occasionally you’ll find nature crates or small patches of vegetation near building walls or loading zones that also yield fungi.
• Quick map sweeps: Because Spaceport is relatively open, short sweeps can net you mushrooms without committing to a long expedition.

Spaceport runs shine when you want consistency and speed. Combine that with safe-pocking (stashing items in secure slots) and you can make reliable progress toward Scrappy’s final upgrade in a handful of raids.

Using Lush Bloom and Other Map Conditions

Certain map modifiers dramatically shift how often nature items, including mushrooms, appear. The most important one for mushroom hunting is typically referred to as a nature-boosting condition, commonly known among players as a lush or bloom-themed event.

What Lush-Type Events Do

When a nature-focused condition is active, you’ll notice:

• Increased nature loot spawns: Mushrooms, olives, and other natural resources become more common across all maps.
• More resource containers: Baskets, crates, and boxes near trees and buildings appear more frequently and tend to contain nature loot.
• Higher returns per route: The same route that normally yields a few mushrooms can now provide significantly more.

These conditions are time-limited, so if your goal is to finish Scrappy upgrades, it’s smart to prioritize mushroom farming whenever they are active.

Best Practices During Lush Conditions

• Run Dam Battlegrounds first: Start with Dam Battlegrounds for bulk farming while the condition is active; the combination of lush spawns and high-density nature POIs is ideal.
• Hit containers as well as trees: Don’t ignore baskets and small crates. The extra mushrooms from containers add up quickly.
• Save some raids for Spaceport: Once you’ve done a big loop or two on Dam, hop to Spaceport and do fast tree-cluster runs to round out your total.

Inventory, Survival, and Efficiency Tips

Mushrooms are valuable but not worth dying for on a risky run. A few smart habits will make your farming sessions far less frustrating.

1. Use Safe Pockets Strategically

Most extraction shooters, Arc Raiders included, use a form of secure inventory slot where items remain safe even if you die. That mechanic exists to reward partial success and mitigate total loss, a pattern that game designers have used widely since at least the early Escape from Tarkov betas.¹

• Prioritize mushrooms in safe slots: As soon as you pick up rare fungi, move them into your secure inventory if possible.
• Extract after key thresholds: If you only need a few more mushrooms for an upgrade, don’t overextend. Extract once you’ve banked what you need.

2. Balance Risk and Reward

Both Dam Battlegrounds and Spaceport can be dangerous, especially around high-value POIs.

• Travel in cover: Use trees, rocks, and terrain dips to avoid open sightlines when moving between mushroom clusters.
• Listen for combat: If you hear heavy fighting near a good mushroom area, consider rerouting to a quieter zone rather than pushing through the chaos.
• Avoid tunnel vision: Mushroom hunting can make you fixate on tree trunks; force yourself to check for enemies regularly.

3. Combine Mushroom Routes with Other Goals

To keep farming from feeling like a chore, weave mushroom gathering into other objectives:

• Complete contracts or bounties that naturally take you through Dam Battlegrounds or Spaceport.
• Farm other nature resources such as olives in their dedicated zones while you’re already in a resource-gathering mindset.²
• Use the time to practice combat with your current build, treating mushrooms as bonus loot rather than the sole objective.

Step-by-Step Sample Farming Plan

If you want a structured, repeatable loop for quickly progressing Scrappy’s upgrades, use this example schedule as a template and adjust to your comfort and gear level.

Phase 1: Early Progress (First Few Mushrooms)

1. Queue into Spaceport.
2. Head straight for the tree cluster between Little Hangar and the adjacent container area.
3. Circle the grove, grab any mushrooms you see, and stash them in safe slots.
4. Extract once you’ve collected a solid handful rather than exploring the entire map.

Phase 2: Bulk Collection on Dam Battlegrounds

1. When you’re comfortable, queue into Dam Battlegrounds.
2. Start at or move toward the Hydroponic Dome Complex, search the interior planters, then sweep the surrounding trees.
3. Follow the river corridor, hitting wooded bends and checking trunks as you go.
4. Optionally, stop at Water Treatment Control and quickly scan the upper pipes.
5. Once your inventory or safe slots are full of mushrooms, head to the nearest extraction lift.

Phase 3: Event-Boosted Farming

1. When a nature-boosting event is active, temporarily focus almost entirely on mushroom runs.
2. Run your Dam Battlegrounds loop first, leveraging increased spawns in domes, forests, and river areas.
3. Swap to Spaceport for fast tree-cluster runs to top off your mushroom count.
4. Upgrade Scrappy as soon as you hit the required mushroom thresholds to avoid overfarming.

Frequently Asked Questions

Do mushrooms only spawn on Dam Battlegrounds and Spaceport?

No. Mushrooms can appear on other maps, especially in nature-heavy or damp locations, but Dam Battlegrounds and Spaceport provide the most consistent and efficient routes. For time efficiency, most players focus on these two maps.

Are mushroom spawns fixed or random?

Mushrooms use a mix of fixed spawn points and randomized activation. Certain trees, planters, or pipe segments can host mushrooms, but they won’t always be active every raid. Running the same route across multiple raids increases your odds of seeing them in those spots.

Can I farm enough mushrooms in one session to max Scrappy?

It’s possible, especially during nature-boosting events, but it will be a long and potentially risky session. Most players will find it more manageable to spread the grind across several shorter runs, banking mushrooms via safe slots and frequent extractions.

Are mushrooms tradable or only for personal use?

Game economies differ across titles and patches. Many extraction-style games restrict key progression materials to personal use to avoid inflation and progression skips.³ Check the current in-game trading rules or official patch notes to confirm whether mushrooms can be traded or sold in your build of Arc Raiders.

How do mushrooms compare to other nature items like olives?

Mushrooms and olives are both nature resources, but they tend to spawn in different types of locations—damp, forested areas for mushrooms versus specialized groves for olives. Both are used in upgrade recipes, but mushrooms tend to feel more scarce because of how spread out their best locations are compared to a single concentrated olive grove POI.²
