TL;DR — The fastest answer
Ermal, the Nomadic Envoy, is a Level 25 barter trader in Speranza who swaps rotating weekly rewards for big-ticket ARC parts — and the Turbine Compressor and Vaporizer Regulator trades are among the ones players chase hardest. They're only worth grinding if you enjoy hunting the ARC Turbine and ARC Vaporizer, because both parts come from dangerous roaming enemies, not vendor shelves. If you just want the reward — or the coins — buying the materials is faster than fighting a Turbine for one drop at a time.
| Question | Quick answer |
|---|---|
| Who is Ermal? | The Nomadic Envoy — a Level 25 barter-only trader in Speranza |
| What does he take? | ARC parts, gear & weapons — never coins (weapon mods are stripped if traded) |
| Turbine part | Turbine Compressor — drops from the ARC Turbine (Riven Tides) |
| Vaporizer part | Vaporizer Regulator — drops from the ARC Vaporizer (+ rare from Couriers) |
| Rewards | Blueprints, cosmetics, items & Raider Tokens, rotating weekly |
| Worth it? | Yes if you already farm these ARC; otherwise buy the parts and skip the fight |
Key Takeaways
- Ermal is barter-only — you spend rare ARC parts and stockpiled gear, not Raider Coins, and any weapon mods on a traded gun are removed first (arcraiders.wiki).
- The two "core" trades players are chasing right now cost the game's most dangerous drops: the Turbine Compressor (from the airborne ARC Turbine) and the Vaporizer Regulator (from the ARC Vaporizer).
- One player summed up the appeal: it can be "43k in large ARC parts sitting on the table" for a single reward — great value if you were already farming those enemies.
- Both parts double as crafting mats (Powered Descender, Dolabra Shotgun) and Expedition/project fuel, so a stack is rarely wasted even if you skip the trade.
- The fastest path if you don't want to fight Turbines all night: buy the materials and spend your session on the reward, not the grind.
What are the Ermal Turbine & Vaporizer trades in ARC Raiders?
Ermal is an envoy from a group of nomadic surface dwellers who "ventured into Speranza in order to trade on behalf of his tribe," per the official ARC Raiders announcement (arcraiders.com). Unlike Speranza's coin traders, he deals exclusively in barter: you hand over ARC components, gear, and weapons to hit a required item value, and in return he offers a rotating stock of blueprints, cosmetics, items, and Raider Tokens that refreshes each week (arcraiders.com).
Two rules matter before you commit parts:
- He's gated behind Raider Level 25. Below that, the Nomadic Envoy tab is locked, so early-game Raiders can't touch these trades yet (arcraiders.wiki).
- Weapon mods are not accepted — if you trade in a modded gun, the mods are stripped off first, so pull anything valuable before you barter it (arcraiders.wiki).
The reason "Turbine/Vaporizer core trades" are a recurring talking point on r/ArcRaiders is simple: the required item value on the best rewards is high, and the cheapest way to hit it is by dumping large ARC parts — the exact components the ARC Turbine and ARC Vaporizer drop. Ermal's exact stock rotates weekly, so always open the Nomadic Envoys tab in-game to confirm the current offers before you farm for a specific one.
Are the Turbine & Vaporizer core trades worth it?
Here's the honest math. The value is real, but it's effort-gated, not coin-gated. As one Raider put it on r/ArcRaiders while weighing the same decision:
"It's 43k in large ARC parts sitting on the table. I think that's a good deal considering the effort to reward ratio of fighting these ARC in the wild (especially the Turbine)." — u/Ness_Bilius_Mellark
That's the whole calculus in one sentence. If you're already hunting Turbines and Vaporizers for Expeditions or crafting, funnelling the surplus into Ermal is close to free value. If you're starting from zero, you're signing up to solo some of the deadliest roaming ARC in the game for a chance at one part per kill — and that's a slow, high-risk grind.
A few guidelines for deciding:
- Trade if you have a backlog of Turbine Compressors / Vaporizer Regulators from other objectives. Offloading them into a blueprint or Raider Tokens beats letting them rot in your stash.
- Skip if the only reason you'd farm these enemies is the trade itself. The kill-to-drop ratio makes it one of the worst pure-profit grinds in ARC.
- Buy if you want the reward but not the fight. Picking up the parts directly turns a multi-raid grind into a single trade — the same logic behind our ARC Raiders Materials service.
Where do Turbine Compressors and Vaporizer Regulators come from?
Both are high-tier ARC enemy drops, which is exactly why they're valuable barter currency.
The ARC Turbine → Turbine Compressor
The ARC Turbine is a new airborne enemy added in the Riven Tides update — a heavily armored machine that flies across the skies and enters a match some time after it starts, most reliably on the Riven Tides map (ign.com). Killing and looting one nets the Turbine Compressor, an Epic material used to craft gear like the Powered Descender and called for in the current Expedition 4 project chain (pcgamer.com, arcraiders.wiki).
The ARC Vaporizer → Vaporizer Regulator
The ARC Vaporizer drops the Vaporizer Regulator along with ARC Alloy, Advanced ARC Powercells, Energy Clips, and Heavy Gun Parts — and you may have to loot it multiple times before a Regulator appears (ign.com). There's also a very small chance to pull Regulators from ARC Couriers or Raider Caches, but hunting Vaporizers directly is the reliable route (playerauctions.com).
How do you farm Turbine Compressors fast?
The Turbine is airborne and armored, so treat it like an event boss, not a patrol:
- Play the Riven Tides map and stay mobile — the Turbine enters mid-match and roams the sky, so keep sightlines open and don't get pinned indoors (ign.com).
- Bring sustained anti-armor fire. This is a heavily armored target; a controllable high-fire-rate gun with good ammo economy beats a hard-hitting single-shot you can't keep on target.
- Loot immediately and extract. One Turbine Compressor is worth more than a risky second engagement — bank the drop.
Community farm guides point at open, courier-heavy zones (for example the Dam Battleground's red-water side) as consistent spots to catch high-tier ARC and their parts, but the drop is still a chance roll, so bring patience.
How do you farm Vaporizer Regulators fast?
The Vaporizer is a flying ARC machine that hovers on eight small rotors, so treat it as an aerial target and win with weak-point discipline rather than raw damage:
- Shoot out the rotors first. The Vaporizer stays airborne on its rotors, and a precision weapon aimed at them drops it toward the ground and ends the fight far faster than dumping mag after mag into its armor (gamerant.com).
- Then punish the underside core. The sphere on its belly is a weak point — once it's grounded, center-mass shots to the underside expose the core and stack damage quickly (community guide).
- Hunt Vaporizers directly rather than praying for Courier/cache drops — direct kills are the only consistent source (playerauctions.com).
- Expect multi-loot RNG. A single Vaporizer may not cough up a Regulator on the first kill, so plan for several fights per part (ign.com).
- Bank the by-products. Even a "dry" Vaporizer drops ARC Alloy, Advanced ARC Powercells, and Heavy Gun Parts, so no kill is truly wasted.
Should you sell, trade, or craft your Turbine & Vaporizer parts?
Before you dump everything into Ermal, remember these parts have three competing uses:
- Craft — Turbine Compressors build the Powered Descender; Vaporizer Regulators craft the Dolabra Shotgun (playerauctions.com).
- Projects & Expeditions — requirements stack up fast. The current Expedition 4 chain alone calls for five Turbine Compressors (stage 3) and three Vaporizer Regulators (stage 4), so keep a reserve before you barter the lot away (arcraiders.wiki).
- Trade — once your crafting and project needs are covered, surplus parts are premium Ermal fuel and often the cleanest way to grab a rotating blueprint or Raider Tokens.
The order of operations that wastes the least: cover your own crafts and active projects first, then trade the overflow. If your stockpile is thin and the reward is time-limited, topping up with a materials pack is usually cheaper than the raids it would take to farm the shortfall — and it leaves your session free for the fun part.

Frequently Asked Questions
Who is Ermal in ARC Raiders? Ermal is the Nomadic Envoy, a barter-only trader who arrived in Speranza to trade on behalf of his nomadic tribe. Instead of coins, he takes ARC parts, gear, and weapons in exchange for a weekly-rotating stock of blueprints, cosmetics, items, and Raider Tokens (arcraiders.com).
What level do you need to trade with Ermal? You must reach Raider Level 25 to unlock the Nomadic Envoy tab. Below Level 25 the trades are locked, so focus on Trials and Expeditions to level up first (arcraiders.wiki).
Are the Turbine and Vaporizer trades worth it? They're worth it if you already farm the ARC Turbine and ARC Vaporizer for crafting or Expeditions, since offloading surplus parts is near-free value. If you'd only farm them for the trade, the low kill-to-drop ratio makes it one of the slower grinds in the game — buying the parts is faster.
Where do you get Turbine Compressors and Vaporizer Regulators? Turbine Compressors drop from the airborne ARC Turbine added in Riven Tides, best hunted on the Riven Tides map. Vaporizer Regulators drop from the ARC Vaporizer, with a small chance from Couriers and Raider Caches (ign.com).
Can you lose the mods on a gun you trade to Ermal? Yes. Weapon mods are not accepted by Ermal and are removed from any weapon you trade in, so strip valuable mods off before bartering a gun (arcraiders.wiki).
Should I sell or trade my Turbine Compressors? Cover your own crafting and active project needs first — Turbine Compressors build the Powered Descender and Vaporizer Regulators craft the Dolabra Shotgun — then trade only the overflow to Ermal for the best rotating reward.
