Onimusha: Way of the Sword Malice Fog Guide — How to Survive & Clear Malice Plants

• The red Malice fog drains your health while you stand in it. Get in, do what you need to do, and get out.
• Malice Plants are the source of the fog — destroy all of them in an area to clear it permanently.
• Prayer Beads are consumable items found in fog areas that let you survive inside the mist without taking damage.
• Stay on rooftops and elevated platforms wherever possible — Malice fog sits at ground level and you take no damage above it.
• Malice Barriers (solid red walls) are different from fog — they require the Oni Strength ability to destroy, which you unlock by beating Rasho-gan.
• Red Threads are invisible spider-silk barriers — use Oni Vision to reveal them, then destroy the spider at the end of each thread.
• Malice Rifts are floating red portals — hit them to expose their core, then seal them to clear the surrounding corruption.

Onimusha Way of the Sword Malice fog is one of the first environmental hazards that genuinely changes how you move through an area. The moment you step into the red mist, your health starts dropping. It does not care about your combat skill or your upgrades — stand in it long enough and you die. This guide covers everything the game throws at you under the Malice umbrella: how the fog works, how to destroy Malice Plants, how to use Prayer Beads, how to clear Malice Barriers and Red Threads, and how to seal Malice Rifts.

These mechanics appear across multiple missions and areas, and understanding all of them early saves a lot of confusion and unnecessary damage. Before diving in, it helps to understand the broader exploration tools available to you — especially Oni Vision, which is the key to spotting most Malice-related hazards. Our tips and tricks for beginners covers Oni Vision alongside every other early-game system worth learning. And since the areas you clear of Malice are the same ones you will be fast-travelling back to for collectibles, understanding how Spirit Mirrors connect to exploration makes a big difference — our Spirit Mirrors guide covers all fast travel and save mechanics in full.

What Is Malice in Onimusha: Way of the Sword?

Malice is the demonic corruption that the Genma have spread across Kyoto. It takes several physical forms in the game — red fog in the air, solid walls blocking paths, spider-silk threads blocking doors, and floating rifts in corrupted swamp zones. Each form works differently and requires a different approach to deal with.

The common thread across all Malice forms is that they are not just cosmetic. Every type either damages you, blocks your path, or spawns enemies until you deal with its source. Malice is the game’s primary environmental challenge, and learning how each type works is as important as learning combat.

Onimusha Way of the Sword Malice Fog

Malice Fog — How It Works and How to Survive It

Malice fog is the red mist that fills certain areas of Kyoto, especially during the main quest “The Curse of Kiyomizu-Zaka Slope.” It is not instant death, but it is a steady health drain that punishes you for standing in it too long without a plan.

How the Fog Damages You

The moment you step into the red fog, your health begins dropping. The drain is slow enough that you can pass through a short stretch without critical danger, but any prolonged time in the mist — fighting enemies, looking for a path, or getting lost — will cost you significant health. On Carnage difficulty, where a single hit can kill, even a few seconds in the fog without preparation is a serious risk.

The fog sits at ground level. It fills streets, courtyards, and open ground areas. It does not rise to rooftop height in most locations. This matters a great deal for how you navigate Malice fog zones.

Stay on Rooftops and Elevated Ground

The most important survival rule in Malice fog areas is: get off the ground as quickly as possible and stay there. Ladders, rooftops, bridges between buildings, and elevated platforms all sit above the fog layer. You take no Malice damage while elevated. The main quest “The Curse of Kiyomizu-Zaka Slope” is almost entirely designed around rooftop traversal — you move from roof to roof, only dropping to ground level when absolutely necessary to climb a ladder or interact with something specific.

Look for ladders going up before you step into any fog-filled street. Most areas with Malice fog have an intended elevated route. If you find yourself walking through thick red mist on the ground for an extended period, you have probably missed a ladder or bridge that would take you above it.

Use Prayer Beads to Survive the Fog

Prayer Beads are a consumable item found in Malice-affected areas. They are placed on glowing spots in and around the fog zones — on rooftops, near ladders, and sometimes inside huts near the affected ground. Picking them up and using them lets Musashi linger inside the Malice fog safely without taking health damage for a limited time.

Prayer Beads are particularly important during “The Roots of All Evil” mission, which takes place in a swamp flooded with red water. In that mission, the fog is unavoidable — you have to enter the water to reach objectives. Prayer Beads are scattered across the mission area to help you survive. As you move through, collect every glowing item you see — many of them are Prayer Beads. Use them before entering deep water rather than after you have already started taking damage.

Blessed Beads are an upgraded version of Prayer Beads that also appear in some locations. They work the same way but last longer. Grab them whenever you find them, even if you do not need them immediately — they go to your Storehouse and are available at any Spirit Mirror later.

Heal Between Fog Runs

Before entering a Malice fog area, use a Spirit Mirror to rest and fully restore your health. Then, if you take fog damage during the area, use yellow souls from killed Genma to top up between bursts of exposure. If you are running low on Hozuki berries and yellow souls are not dropping fast enough, retreat to elevated ground to stop the drain before using a heal.

For more on managing your health resources efficiently during demanding areas, our soul farming guide covers how yellow soul drops work and how to generate more healing from Oni Armament hits during combat.

How to Destroy Malice Plants

Malice Plants are the source of the red fog. They are large, grotesque red growths embedded in the environment — usually on the ground in or near the heaviest fog zones. Destroying all the Malice Plants in an area permanently clears the fog from that zone. The townsfolk come back out, the streets open up, and the area becomes fully safe to explore.

Finding Malice Plants

Malice Plants are visible without Oni Vision — they glow with red energy and are large enough to spot clearly. They are not hidden. The challenge is getting to them through the fog and the Genma guarding them, not finding them visually.

Use your Oni Vision scan while moving through a fog area to confirm you have found all plants. Oni Vision: Treasures and Oni Vision: Search Range — two skills available at the Spirit Mirror — help reveal nearby points of interest. If you have not already bought these three Oni Vision skills, do so before attempting Malice fog missions. They make tracking down every plant significantly easier.

How to Destroy Them

Walk up to a Malice Plant and attack it. A few strikes will destroy it. There is no special mechanic or item required — you just need to reach it and hit it. The challenge is that Genma enemies are almost always guarding the path to each plant or standing directly near it. Clear the enemies first, then break the plant.

In “The Curse of Kiyomizu-Zaka Slope,” there are multiple Malice Plants spread across the area. After destroying each one, the fog in the immediate surrounding section lifts. Breaking the later plants also triggers Rift openings nearby — mini-bosses spawn from them. Be ready for a fight immediately after each plant is destroyed. Do not assume the area is clear just because the plant is down.

Byakue — The Mini-Boss Guarding the Final Plant

Before you can destroy the final Malice Plant in the Kiyomizu-Zaka area, Byakue appears to stop you. This is the animalistic Genma that also appears as a secret boss in the demo. In the full game, it is a mandatory fight tied to the main quest.

Byakue’s key behaviour: it gets coated in its own blood as the fight goes on, which triggers a frenzy mode. Using fast, one-handed attack strings speeds up how quickly this frenzy triggers. The recommended approach is to use slower, heavier two-handed strikes — fewer hits, more damage per blow — to avoid triggering the frenzy prematurely. Deflect its weapon strikes to drain its stamina, and dodge its charge and tackle moves. Once its stamina breaks, land a Break Issen to end the fight efficiently. Defeating Byakue rewards you with Byakue’s Talisman x2, a material needed for gauntlet upgrades.

After Byakue falls, destroy the final plant and the fog clears from the whole area permanently. For the specific Issen and deflect timing you need to handle Byakue confidently, our guide on mastering Issen, parry and deflect covers the full mechanics.

Malice Rifts — How to Seal Them

Malice Rifts are a different type of Malice corruption that appears later in the game, most prominently during “The Roots of All Evil” mission. They are floating red portals hovering in the air above corrupted ground or swamp water. They spawn Genma enemies and sustain the red corruption around them until sealed.

How to Seal a Malice Rift

Hit the rift with either your Oni Bow or a melee strike to expose its glowing core. Once the core is visible, attack it directly to seal the rift. The mission objective counter — displayed under the mission name on your HUD — ticks up each time you successfully seal one. If the counter does not change after you attack a rift, the seal did not land and you need to hit the core again.

In “The Roots of All Evil,” you need to seal three rifts spread across a swamp area. The layout is a tangle of winding paths, huts, elevated bone structures, and flooded ground. Wall-running across the large bone structures is the intended traversal route between locations. Use your Oni Bow for rifts that are positioned out of comfortable melee reach or above the waterline — do not jump into the red water to reach a rift when you can shoot it from higher ground.

After sealing each rift, the red corruption drains from the surrounding area. Loot the huts and surrounding ground as you go — Prayer Beads, Tamahagane, Leather, Unrefined Sake, Cotton Cloth, and Heavy Restoratives are scattered through this mission and worth collecting for upgrades.

Malice Barriers — The Red Walls

Malice Barriers are solid red walls made of sinew and stone that block entire sections of the map. They look like a physical barrier rather than mist or fog. They are completely different from Malice fog — you cannot pass through them, walk around them, or damage them early in the game. They are a progression gate.

How to Remove Malice Barriers

You cannot destroy Malice Barriers until you have the Oni Strength ability. This ability unlocks after defeating Rasho-gan, the Wish Warper, during the main quest “Careful What You Wish For.” Beating Rasho-gan grants you Oni Strength, which lets you interact directly with any Malice Barrier you find. Walk up to the barrier, use the prompt to spend Oni Power, and it breaks apart to open the path.

The first Malice Barrier you encounter is at Kiyomizu-dera Temple, blocking the route to the high platform. Do not waste time trying to find a workaround early — there is none. Mark it mentally (or use your map) and come back once you have Oni Strength.

After unlocking Oni Strength, it is worth going back systematically through every area you have already visited and clearing every Malice Barrier you passed. The spaces behind them are not empty — some contain good loot, and a few hide encounters you cannot find any other way. Work through your map area by area rather than just clearing the nearest barrier and continuing the main story.

Oni Strength and Shielded Enemies

Oni Strength does double duty. The same ability that destroys Malice Barriers also lets you break through shielded enemy defences. Some Genma carry large shields that block standard attacks entirely. Using Oni Strength on them destroys the shield directly, leaving them open. This is relevant in Malice fog zones where shielded Genma sometimes guard the path to a plant — you do not have to spend time trying to flank them. Use Oni Strength and break the shield. For more on combat efficiency against armoured enemies, our combat and controls guide covers every mechanic in the full toolkit.

Red Threads — How to Clear Them

Red Threads are a fourth type of Malice obstacle, distinct from fog, barriers, and rifts. They are invisible barricades blocking doors and passages, generated by hidden spiders. The game explains the mechanic early on, but the process is easy to fumble in the middle of a combat-heavy area.

How Red Threads Work

You will not see a Red Thread barrier with the naked eye. The first sign is your Oni Gauntlet flickering as you approach one. When that happens, trigger Oni Vision — press the two Oni Vision buttons together — and the barrier becomes visible: a thick red mass with individual threads trailing off in different directions. Each thread leads back to a hidden spider somewhere in the environment.

Your job is to follow each thread to its spider and destroy it. With most Red Thread barriers having two or three threads, you need to find and kill two or three spiders to clear the passage. Each spider is small, stationary, and dies in one or two hits. The challenge is locating them — they can be on rooftops, inside adjacent rooms, or in elevated spots that are not immediately obvious from where you are standing.

Tips for Clearing Red Threads Efficiently

• Switch to your Oni Bow before triggering Oni Vision. Spiders do not stay revealed for long once you use Oni Vision. If a spider is up on a rooftop or out of sword range, you need to shoot it quickly. Fumbling a weapon swap after the fact wastes the reveal window and forces you to start over.
• Clear enemies in the area before dealing with the threads. Trying to track down and shoot spiders while Genma are actively attacking you is a reliable way to lose track of a thread mid-pursuit. Fight first, then clear the threads in peace.
• Pulse Oni Vision again if you lose a thread. You can re-trigger Oni Vision as many times as needed to re-reveal the barrier and remaining threads. It is not a one-use reveal — use it freely.
• Check the obvious room first. Many early Red Thread encounters have at least one spider inside an adjacent room or directly along the corridor. Walk the thread path visually before assuming it goes somewhere complicated.

Malice Fog Areas and What Opens Up After Clearing

Clearing Malice fog is not just a survival task — it directly affects how much of Kyoto you can access and explore. After the Kiyomizu-Zaka area is cleared, the townsfolk return to the streets, new NPCs become available, more of the city opens for exploration, and Chance Encounter events start appearing in the area. Some of these side missions only become accessible once the relevant area of Kyoto is clear of Malice.

This makes clearing Malice fog directly relevant to trophy hunting. Chance Encounters are required for the No Job Too Small Silver trophy, and many of them are in areas that only open after you clear the local Malice. Complete every Malice plant mission as soon as the story sends you there, rather than rushing through to the next objective. The Chance Encounters and collectibles that unlock afterwards are time-sensitive in the sense that they reset in New Game+, so doing them on your first run is important.

For the full picture of what resets and what you need to complete before the final mission, see our trophy and achievements platinum roadmap.

Malice and the Boss Fights That Go With It

Every Malice Plant mission comes with boss or mini-boss encounters attached. They are not optional. Here is what to expect:

• Byakue — appears before the final Malice Plant in the Kiyomizu-Zaka area. Use heavy two-handed strikes, avoid triggering the frenzy early, deflect weapon attacks. Rewards Byakue’s Talisman x2.
• Genma from Rifts — after breaking a Malice Plant in some areas, a Rift opens and spawns a wave of Genma including a tougher lead enemy. Stay on elevated ground if possible, clear the regular enemies first, then focus the named enemy.
• Rasho-gan — the boss that unlocks Oni Strength for clearing Malice Barriers. He is encountered during “Careful What You Wish For.” Deflect is more reliable than parry against his multi-hit combos. In Phase 2, position yourself near walls and dodge his grab carefully.

For individual boss strategies, our Sasaki Ganryu guide covers the game’s tutorial boss, and our Shuten Doji boss guide handles one of the later, harder fights. The Flow State trophy guide also covers combat mechanics that are useful when fighting in the confined, fog-heavy areas where Malice Plant encounters take place.

Tips for Malice Fog Areas on Carnage Difficulty

On Carnage difficulty, Malice fog zones become significantly more dangerous for two reasons: the health drain matters more when a single enemy hit is already potentially fatal, and you cannot rely on Action Prompts to help time your defensive options in the combat encounters that punctuate fog zones.

• Use Prayer Beads as soon as you enter any fog zone on Carnage. Do not try to conserve them. The health drain combined with enemy hits in a fog zone can kill you far faster than on Action or Story mode.
• Prioritise elevated routes aggressively. Every second on ground level in a fog zone is a second of health drain on top of any damage you take. Look for the first ladder upward before doing anything else in a fog area.
• Kill Byakue with deliberate two-handed hits only. Fast attack spam on Carnage triggers his frenzy almost immediately. Slow, heavy hits with your two-handed stance let you control the fight pace and avoid the frenzy entirely.
• Stock your Hozuki Pouches before Malice missions. Heal items are more important here than in standard exploration because the ambient damage compounds with combat damage. Start every Malice fog mission at full health and with full pouches. Rest at the nearest Spirit Mirror before the mission begins.
• Use your Oni Bow to hit Rifts from safe positions. On Carnage, jumping into the red water under a rift to hit it in melee range is unnecessary risk. Stay elevated, use the bow.
