Quick answer: Haywire Zones are the four anomalous weather areas of Isles of Abyss, the new PvE ocean scenario that launches in Once Human after maintenance on October 21, 2026 (PT) (October 22 in Europe and Asia). Each zone lives on its own island group and changes the survival rules there. Mist of Deceit (Reefshadow Bay) shrinks your vision as your HP drops. Black Tide (Misty Marsh) brings Stardust contamination that eats your Sanity. Time Rain (Spring Valley) drains Energy, Hydration and gear durability but speeds up crop and animal growth. Skyfire (Falling Ember) drops meteors that damage you and your buildings and heat the area up. Each one also drops a special resource you need for ships, diving gear and production, and each has a dedicated counter item. The full list is below.
This guide is built from the official Isles of Abyss dev blog published October 16, 2026 on oncehuman.game. It covers what every Haywire Zone does, what it drops, and what to bring. Isles of Abyss is free on PC, PS5, PS5 Pro, Xbox Series X/S and mobile with full cross-play, so everything here applies on every platform. We'll update this page with hands-on numbers after launch. For now, every effect and item name comes straight from the studio.
What are Haywire Zones in Once Human?
Haywire Zones are areas of the archipelago where the weather has gone wrong, and they're the main environmental hazard in Isles of Abyss. The studio describes them like this in the October 16 dev blog:
"In Haywire Zones, phenomena such as the Mist of Deceit, Black Tide, Time Rain, and Skyfire will change the local exploration rules: they bring survival pressure in terms of view, temperature, sanity, and supply consumption, and also produce corresponding special resources." (Once Human dev blog, October 16, 2026)
That sentence covers the whole design. Each zone puts pressure on one or two of your survival stats, and each one is also the only practical source of a resource you'll want for your ship, your diving kit or your base. You can't just avoid them. You go in prepared, take what you need and leave before the zone wears you down.
Here's the at-a-glance version:
| Haywire Zone | Island group | What it does to you | What it gives you | Main counter items |
|---|---|---|---|---|
| Mist of Deceit | Reefshadow Bay (cold north-west) | Lowers temperature; limits vision (lower HP = smaller field of view) | Mist of Deceit Wicks (from Mist Core Grass) for cannonballs and electricity facilities | Mist Core Clarity Soup, Blaze Core Lantern |
| Black Tide | Misty Marsh (giant-tree swamp) | Deepening Stardust contamination; gathering drains Sanity | Black Tide Clots, Stardust Ore, contaminated plants | Black Tide Protective Mask, Sanity-restoring drinks |
| Time Rain | Spring Valley (hot, humid mangrove coast) | Faster Energy and Hydration drain; gear in your backpack loses durability | Bottled Raindrops; faster crop and animal growth | Time-Reverse Cookies, Time-Reverse Raincoat |
| Skyfire | Falling Ember (volcanic island) | Meteors damage players and buildings; area heats up; big meteors spawn guards | Skyfire Gold and rare minerals | Cooling Patch, All-Weather Stew |
Two more rules from the dev blog matter before you sail:
- Haywire Zones change as the scenario phase progresses. Isles of Abyss runs a roughly 21-day cycle: Phase I lasts about 5–10 days (it gets shorter as your server's purification progress climbs) and Phase II lasts 11 days. What you meet in a zone on day 2 won't be what you meet in Phase II.
- Small islands between the main islands are there for docking, resupply, gathering and preparation. Use them to swap gear before you push into a zone.
Mist of Deceit: how to survive Reefshadow Bay
Where: Reefshadow Bay, the north-western end of the archipelago, near the cold northern continent. Cold tundra, reef cliffs, floating ice, bones, coral and old mining ruins.
What it does: Mist of Deceit lowers the environment temperature and limits visibility, and visibility depends on your health: "the lower your HP, the smaller your field of view." That's the dangerous part. The moment a fight goes badly you can see less, so you're more likely to get hit again. The dev blog also says that keeping a larger field of view in the mist earns greater exploration rewards. Staying healthy isn't just about survival here. It pays out.
What it drops: gathering Mist Core Grass yields Mist of Deceit Wicks, which are used for cannonballs and electricity facilities. If you plan to fight Voyagers or Calamity Towers with ship cannons, you'll be coming back here.
How to counter it:
- Mist Core Clarity Soup: increases Cold Resist and lets you see through the Mist of Deceit. This is the one to bring.
- Blaze Core Lantern: when active, it raises your temperature and disperses the mist around you, but it continuously consumes durability. Switch it on for the push, not for the whole trip.
- All-Weather Stew: raises both cold and heat resistance. It's a good backup if you're going between Reefshadow Bay and Falling Ember on one voyage.
- Settlements in the area may hold "special items to deal with the Mist of Deceit," according to the studio, so search them.
Tactics: heal early and often. HP controls how far you can see, so topping up at 70% beats topping up at 30%. Fight from range where you can, and don't chase enemies deeper into the mist when you're hurt.
Black Tide: Sanity, Stardust and Misty Marsh
Where: Misty Marsh, a dense forest of giant trees, toxic marshes, fungi and rotting wood, with sunken-ship caves and a trade zone built up in the trees. The giant trees can't be chopped down, but their trunks and canopies hold gatherable resources: Tidal Gum (for rubber) from the trunk and Tidal Fruit (for dishes) from the canopy.
What it does: the Black Tide brings "ever-deepening Stardust contamination" to Misty Marsh. On top of that, special Pollution Zones (Wild, Phantasmal and Mirror) appear at specific locations.
What it drops: Stardust Ore, contaminated plants, and Black Tide Clots. You gather the clots from the black water near Sporocysts, and they're used for diving items and water-circulation facilities. Here's the catch: gathering clots consumes Sanity, and the studio says "maintaining higher sanity allows you to obtain more clots." Arrive with full Sanity and you get more out of every run.
How to counter it:
- Black Tide Protective Mask: when active, it slows Sanity loss inside Black Tide areas, and it consumes durability while it runs. It's the core item for this zone.
- Heavenly Calm Soup: the more seafood you put in when you cook it, the higher the Sanity recovery and pollution resistance it gives. Stock up on Barnacles, Crabs, Lobsters and Oysters before a Misty Marsh trip.
- Old Captain's Spirit: restores Hydration and Sanity and reduces damage taken, but causes severe drunken vision sway. Don't drink it before a fight where you need to aim.
- Drunken Sprint: restores Hydration and Sanity and gives a sprint speed bonus when you're hit. It's the better drink for gathering runs where you might need to run.
Tactics: treat Sanity as the resource you're spending. Mask on, gather until Sanity starts to slide, drink, repeat. If you're new to how Sanity works in Once Human, the Black Tide is where you'll learn it the hard way, because your gathering yield depends on it directly.
Time Rain: Spring Valley's double-edged weather
Where: Spring Valley, a hot, humid coast of mangroves, swamps and waterfalls, with sea arches, whirlpool caves and skeletal Wonders. Giant crocodiles also show up here as an extra threat.
What it does: Time Rain accelerates Energy and Hydration consumption and makes items and gear in your backpack continuously lose durability. At the same time, it speeds up the growth of crops and animals, both in the wild and in your own territory.
That second half is why Time Rain is the most interesting zone in the scenario. It hurts while you're out in it, but it's a production boost for anyone farming or ranching. The studio puts it plainly: "Managing your supply well also lets you use Time Rain to gain faster production returns."
What it drops: Bottled Raindrops, from defeating enemies and gathering crops in the rain. They're used for water-based production and for farming and breeding facilities.
How to counter it:
- Time-Reverse Cookies: give immunity to Time Rain's effects on your body for a while, so your Energy and Hydration don't drop rapidly. They cover your body stats; the dev blog doesn't say they protect your gear.
- Time-Reverse Raincoat: gives immunity to Time Rain's effects, but slightly reduces movement speed and consumes durability.
- Time-Reverse Welding Torch: restores durability on buildings and facilities after long sails and fights, so pack one if you plan to base near the rain.
Tactics: carry only what you need. Everything in your backpack loses durability while it's raining, so don't haul your best spare weapons through Spring Valley. Bring extra water and food on top of the Cookies, and watch for the crocodiles at the waterline. The Bay Crocodile is also the scenario's new capturable mount: the dev blog says you can catch one with a Tranquilizer Throwing Needle, raise and breed it in your territory, and ride it on the water for damage reduction for both you and the croc.
Skyfire: meteors, heat and Skyfire Gold on Falling Ember
Where: Falling Ember, an active volcano in the middle of the ocean. Lava, black sand and basalt, with hot springs and sulfur scattered around. Gathering hot-spring water gives you Sulfur Water, which you can refine into sulfur.
What it does: when Skyfire comes down, meteors damage nearby players and buildings and make the surrounding area continuously heat up. Larger meteors spawn Deviant enemies that guard them.
What it drops: mining meteors yields Skyfire Gold and rare minerals, used to craft alloy ship structures, automated gathering facilities and more. Bigger meteors are harder to mine, and the area's temperature returns to normal once mining is complete. Cleaning up a meteor is how you cool the area down.
How to counter it:
- Cooling Patch: removes Heatstroke, keeps lowering your body temperature and consumes durability.
- All-Weather Stew: increases both heat and cold resistance.
- Territory protection can protect your base and withstand attacks for a period of time. If you've built on or near Falling Ember, that matters when meteors hit buildings.
Tactics: don't build your main base where Skyfire falls. Your ship doubles as movable water territory, so you can park it offshore, go in, clear the guards around a large meteor first, then mine it out. Only larger meteors spawn guards, so bring a team for those.
How should you prepare before entering a Haywire Zone?
The dev blog's own advice is short: prepare protective items, dishes and supplies in advance according to the environment type. In practice, that's a loadout per island:
| Going to… | Must-bring | Nice to have | Leave behind |
|---|---|---|---|
| Reefshadow Bay (Mist of Deceit) | Mist Core Clarity Soup, healing | Blaze Core Lantern, All-Weather Stew | Nothing in particular; just stay healthy |
| Misty Marsh (Black Tide) | Black Tide Protective Mask, Heavenly Calm Soup | Drunken Sprint | Old Captain's Spirit if you'll be fighting |
| Spring Valley (Time Rain) | Time-Reverse Cookies or Raincoat, extra water and food | Tranquilizer Throwing Needle for a Bay Crocodile | Spare high-value gear (durability drain) |
| Falling Ember (Skyfire) | Cooling Patch, mining tools | All-Weather Stew, a squad for large meteors | Your main base location |
Three general rules on top of that:
- Every counter item burns durability. The Lantern, Mask, Raincoat and Cooling Patch all wear down while active. Carry a way to repair or replace them, or turn them off when you're out of the zone.
- Food is a stat in this scenario. Seafood dishes are built around the ocean: Fresh Fish Dishes reduce Energy and Hydration use while swimming, Silky Fish Oil Soup reduces swimming consumption, and Stealth Cuttlefish Sashimi shrinks the range at which underwater enemies lock onto you.
- Gear depends on Tech here. Characters start at max level in Isles of Abyss, but the rarity of gear you can craft and the number of active Mod attributes unlock with your Tech progress. Your existing Blueprints and Mods come with you as normal. The Haywire Zone resources feed that Tech curve, which is why you can't skip them.
Why Haywire Zones matter for your ship and the Sunken Lord
Haywire Zones aren't side content. Look at where their drops go:
- Mist of Deceit Wicks become cannonballs and electricity facilities.
- Black Tide Clots become diving items and water-circulation facilities.
- Skyfire Gold becomes alloy ship structures and automated gathering.
- Bottled Raindrops feed farming and breeding.
Ship cannons and better hulls are what you need for Calamity Towers, the Phase II Sea Calamity Zones and eventually the Sunken Lord, the scenario's final boss, which appears when your server's purification progress reaches 100%. A server that farms its Haywire Zones well gets its ships and diving kit up faster, and that's what moves everyone toward the endgame. See our Sunken Lord boss guide for how that progression works, and the Isles of Abyss shipbuilding guide for what those materials go into.
What we don't know yet
To be straight about the limits of a pre-launch guide: the studio hasn't published how often each Haywire Zone triggers, how long each event lasts, exact Sanity, temperature or durability numbers, or drop amounts for Skyfire Gold, clots, wicks or raindrops. Anyone quoting those before October 21 is guessing. We'll add measured numbers after launch. The scenario also ran an NDA closed test before launch, so we don't use leaked test footage or figures.

FAQ
What are Haywire Zones in Once Human? Haywire Zones are anomalous weather areas in the Isles of Abyss scenario. Four were announced: Mist of Deceit, Black Tide, Time Rain and Skyfire. Each one changes the survival rules on its island group (vision, temperature, Sanity or supply drain) and produces a special resource you need for ships, diving gear and production.
Where is each Haywire Zone in Isles of Abyss? Mist of Deceit is in Reefshadow Bay in the cold north-west, Black Tide is in Misty Marsh, Time Rain is in Spring Valley, and Skyfire is on Falling Ember, the volcanic island. Fragrant Cape, the starting island, isn't one of the four named zones.
How do you see through the Mist of Deceit? Eat Mist Core Clarity Soup, which increases Cold Resist and lets you see through the mist, or activate a Blaze Core Lantern to disperse the mist and warm up (it uses durability). Keep your HP high too, because the lower your HP, the smaller your field of view.
How do you stop losing Sanity in the Black Tide? Wear the Black Tide Protective Mask, which slows Sanity loss in Black Tide areas, and recover with Heavenly Calm Soup, Old Captain's Spirit or Drunken Sprint. Keep Sanity high while gathering, because higher Sanity means more Black Tide Clots.
Is Time Rain good or bad? Both. It drains Energy, Hydration and the durability of items in your backpack, but it also makes crops and animals grow faster, including in your territory. Time-Reverse Cookies protect your body stats and the Time-Reverse Raincoat blocks the effects at the cost of a little movement speed.
What is Skyfire Gold used for? Skyfire Gold comes from mining Skyfire meteors on Falling Ember. It's used to craft alloy ship structures, automated gathering facilities and more. Mining a meteor out also returns the area's temperature to normal.
Is Isles of Abyss PvE or PvP? The official October 16, 2026 dev blog lists the scenario type as PvE. It launches after maintenance on October 21, 2026 (PT) on PC, console and mobile, with a permanent server expected around November 12, 2026 (PT).
