ARC Raiders has a way of punishing overconfidence fast. You drop into a raid with a solid weapon and a rough plan, and fifteen minutes later you're pinned down, over-encumbered, staring at a locked container you can't open, wondering where it all went wrong. The answer is almost always the skill tree. The best PvE build isn't the flashiest one — it's the one that gets you out with the expensive loot still in your backpack. This guide breaks down the full 86-point PvE skill build, every skill worth taking, the traps to avoid, and the exact progression order to follow.
What makes a PvE skill build different from PvP?
A lot of bad PvE builds are just PvP builds with a different coat of paint. PvP players optimize for dueling, burst movement, and winning fights against other humans. PvE players need something less glamorous but more profitable: stamina management, loot access, carry weight, and enough recovery tools to survive their own mistakes.
The best PvE skills do one of four things. They help you reach more loot, help you carry more loot, help you move longer without running dry on stamina, or help you recover when a raid starts falling apart. Skills that don't fit any of those categories deserve serious skepticism before you spend points on them.
Security Breach unlocks special containers
What is the best overall PvE skill priority?
The build follows a clear three-phase structure: start in Mobility for stamina, rush Survival for Security Breach, then move into Conditioning to reduce gear penalties and speed up breaching.
Security Breach is the single most valuable PvE skill available. It unlocks special containers that can produce epic weapons, explosives, grenades, wolf packs, and rare blueprints including Anvil, Ventor, and Oper. Every skill you take before it is just the path to get there.
Phase 1: How to build your Mobility foundation
Your first 14 points go into Mobility, and the goal is stamina, not movement tricks.
Youthful Lungs is mandatory and should be maxed immediately. Stamina is your escape budget, your repositioning budget, and your "I made a bad call and need a second chance" budget. More of it improves every minute of every raid.
Marathon Runner gets maxed right after. Together, these two skills attack stamina from both sides: Youthful Lungs increases your pool, Marathon Runner slows how fast you drain it. That pairing is the foundation of the entire build.
Put 1 point into Nimble Climber early because it opens the path to better skills. You can add more later, but don't get distracted here. Once you hit roughly 14 Mobility points, stop and pivot into Survival.
Phase 2: How to rush Security Breach through the Survival tree
Once your stamina foundation is set, move into Survival and don't stop until Security Breach is unlocked.
Looter's Instinct gets maxed first. It reveals loot faster when opening containers, which sounds minor but compounds across dozens of interactions per raid. Less time with your face in a container means less time standing still while the map decides your fate.
Crouched Movement is a pathing skill. Take it because the tree requires it, not because it changes your runs. Don't emotionally invest in it.
Traveling Tinkerer enables mid-raid field crafting. This is the skill that turns a bad situation into a recoverable one. Without it, your starting loadout is your whole plan. With it, your plan can adapt.
Raider Scraps gives an extra chance to find field-crafted items in raider containers. Max it. More meds and utility resources reduce pressure on your starting gear and let you push further without adding more risk.
Broad Shoulders and Looter's Luck both get maxed before you reach Security Breach. Broad Shoulders increases carry weight, which directly determines how much value you extract per successful run. Looter's Luck gives a chance to reveal twice as many items per container, which speeds up decisions and reduces exposure time.
Once Security Breach is available, unlock it immediately. Not after experimenting with other branches. Immediately.
Good As New is worth grabbing once the core Survival path is done. It increases stamina regeneration while under a healing effect, and it pairs well with cheap healing items like fabric. That turns basic healing into a stamina recovery tool during long escapes and extraction pushes.
Phase 3: How to use Conditioning to make your gear feel right
Conditioning doesn't have a dramatic single unlock like Security Breach, but it fixes the quiet friction that drains your runs over time.
Used to the Weight reduces how much wearing a shield slows your movement. The practical effect is that medium shields feel closer to light shields. In PvE, being slightly faster affects whether you can break line of sight, reach cover, and rotate safely while carrying heavy loot.
Proficient Prior reduces breaching time for doors and containers. This skill becomes more valuable after Security Breach because you'll be spending more time at special containers and restricted access points. Shorter breach time means less commitment, less exposure, and fewer moments where you're standing still hoping nothing notices.
Loaded Arms reduces how much your equipped weapon impacts encumbrance. This is one of the most important Conditioning skills. Better gear is usually heavier gear, and a build that looks strong on paper but makes you move like you're underwater is not a good build.
After those three, add Turtle Crawl and Downed But Determined. Neither is glamorous. Both matter. Turtle Crawl extends your downed-state window before full collapse. Downed But Determined stacks with it for more recovery time. In squad play, those extra seconds can mean a teammate reaches you before the run falls apart. In solo play, they buy time for pressure to shift.
A Little Extra gives more ARC circuitry from breaching couriers and probes. It's useful if your route regularly hits probes, but it's mostly in the build as a pathing step toward other Conditioning skills.
Phase 4: What late Mobility skills are worth taking?
Once the loot engine and Conditioning core are stable, return to Mobility for polish.
Effortless Roll reduces dodge roll stamina cost. It's not a replacement for Youthful Lungs or Marathon Runner, but once your stamina pool is large enough, reducing roll cost makes movement feel cleaner during ARC fights and repositioning sequences.
Carry the Momentum lets you briefly maintain sprint momentum without immediately losing all stamina. One point is worth it for the cost. The effect supports the broader stamina economy without demanding heavy investment.
Vigorous Vaulter is a late comfort skill for players who route through vertical or obstacle-heavy areas. It should never compete with the core build for points.
Which skills should you skip entirely?
Some skills aren't worth early investment. Some aren't worth investment at all.
Extended Slide changes slide distance in ways that can disrupt muscle memory and push you out of cover at the wrong moment. Predictable movement beats dramatic movement in PvE every time.
Fall Damage Reduction is described in testing as negligible. If the best case for a skill is "barely helps when you make a specific mistake," it should not compete with stamina, loot access, or Security Breach progression.
Stamina Regen While Crouched has a very small reported effect. Take it only if the tree path requires it.
Hearing Protection reduces explosion impact on your senses. The opportunity cost is too high. If you're close enough to explosions often enough for this to matter, better positioning is the fix, not a skill point.
Effortless Swing and Sky Clearing Swing are melee-oriented skills. This build is about loot efficiency, not philosophical melee statements.
Deep Thrifts was untested even in the source build notes. When proven options exist, don't spend early points on unknowns.
What's the best build for different PvE playstyles?
The 86-point build works broadly, but the emphasis shifts depending on how you play.
Solo players should optimize for avoiding bad situations rather than winning them. Every skill should help you leave, not fight. Squad players can specialize: having three loot-focused players is funny until nobody can stabilize a fight.
Common mistakes players make with the PvE skill tree
Delaying Security Breach is the most expensive mistake. Every raid you run without it is a raid where your loot ceiling is lower than it needs to be.
Over-investing in Mobility gimmicks is the second most common error. Stamina is good. Predictable movement is good. A longer slide that ends with you kneeling in front of something angry is neither.
Ignoring encumbrance is how players end up with great gear that makes them move like they're carrying furniture. Loaded Arms and Used to the Weight exist specifically to prevent that.
Treating Turtle Crawl and Downed But Determined as failure skills is the wrong frame. They're insurance. If one extended downed timer saves a backpack full of rare loot, those points earned their place.
Finally, copying PvP builds for PvE almost never works. PvE asks different questions: can you loot faster, carry more, open special containers, and extract safely? If your build can't answer those questions, it's not a PvE build.
