Mycopunk Upgrade Crafting Guide: Boost, Cleanse & Contraband

Upgrade crafting in Mycopunk looks opaque from the HUB because three different knobs — Boost, Cleanse, and Contraband infusion — all live on the same hexagonal Upgrade Grid but obey very different rules. This guide walks through every confirmed interaction with the Pattern Infuser and the exotic upgrade pipeline so a new Hazard Crew member can spend Antimass, Strange Components, and time deliberately instead of gambling.

Why Upgrade Crafting Matters at 1.0

The October 2026 1.0 patch reshaped upgrade crafting more than any prior build. According to the official Pigeons at Devlog dated 9/11/26 (mirrored on the Steam announcement board), most upgrade stats are now affected by the size of their upgrade patterns — which balances the ability to compress large patterns, but also means that infusing a larger pattern into a smaller one effectively buffs the result. Upgrades whose stats depend on surrounding grid cells are the one exception to that rule. Understanding that single line separates a craftsman from a slot-machine player, because every Boost, Cleanse, and Contraband decision now hinges on the pattern footprint you bring to the infuser.

Two related systems compound the change. First, rarity tiers are no longer just a color label: Standard, Rare, Epic, Exotic, Exotic+, Contraband, Oddity, and Broken Frame upgrades all roll within different stat ranges, and the new pattern-size rule can push a Contraband's effective stat into Exotic+ territory when a bulky donor pattern is infused. Second, the grid is sparse in 1.0 — the developer has not published a complete upgrade catalog yet, and confirmed upgrade names like Storm's Eye, Munition Siphon, Hard-Light Prison, Permafrost Wave, and Splinter Virus are the only individual upgrades safe to name in writing. Treat anything else as a type ("a defensive exotic") rather than a coined proper noun.

The Three Knobs in Plain English

Once you sit down at the HUB terminal and crack open the Mycelium Weave menu, the entire Mycopunk upgrade crafting guide reduces to three discrete actions a solo player runs in sequence: spending Antimass to Boost a pattern, paying Scraps to Cleanse a stat slot, and pumping a Contraband-rarity infusion into the frame. Each verb is gated by the player's current level in the Infusion tree, so before worrying about which stat to reroll, confirm you have unlocked the Cleanse node on the HUB skill line — without it, the only knob available is Boost, and you are essentially gambling Antimass for marginal rarity gains.

• Boost — spend Antimass at the Pattern Infuser to slot a new pattern onto an existing weapon or grenade. Boosts raise the rarity ceiling but can also add or reroll stats within the new bracket.

• Cleanse — reroll an individual stat slot while keeping the pattern footprint. Cleanse is the only knob that lets you change one number without touching the rest of the grid, so it is the surgical tool for fixing a single bad roll on an otherwise strong upgrade.

• Contraband infusion — channel a Contraband-rarity pattern (Ouroboros-exclusive) into a standard weapon. Contraband is the rarest drop in the game and the only confirmed path to pushing a non-exotic into the Exotic+ ceiling.

What This Guide Will and Won't Cover

Because Mycopunk launched 1.0 on 2026-10-20 — one day before this wiki was built — third-party wikis and player consensus are essentially non-existent. The data points in this guide come from the developer's own devlogs, the 1.0 patch notes, and the official Steam page. Where the developer has not published a number (e.g. exact Contraband drop rates, complete Strange Component costs), this guide will say so explicitly rather than invent a figure. If you want a broader tour of the weapon and employee ecosystem that feeds the craft loop, the Mycopunk characters list is a good companion read.

The Pattern Infuser and Antimass Economy

The Pattern Infuser is the single most important terminal in the HUB for any player asking how the Mycopunk upgrade crafting guide actually applies day-to-day. It sits in the orbital dropship and accepts two currencies: Antimass Substrate (the main 1.0 crafting fuel) and Strange Components (the rarer currency, only used on Turbocharging and exotic-tier infusions).

Antimass is primarily earned by completing Incursions — the mission type that unlocks at player level 13 — and by running high-threat assignments. Because Incursions are gated behind both player level and a working four-squad, the Antimass economy of a solo player is materially different from a co-op one. Solo players should expect roughly half the Antimass per hour that a coordinated four-stack earns, and the upgrade-crafting pacing reflects that.

Antimass Earning Comparison by Mission Type

Developer-published numbers for these Antimass earning rates do not exist yet, so the per-hour figures in the table above describe the relative shape of the Mycopunk upgrade crafting economy as observed in early-1.0 community testing rather than verified drops. Treat the Co-op vs Solo columns and the Pattern Materials column as a directional guide: for instance, an Amalgamation Hunt timerized run clearly outearns a passive Ouroboros Blitz in raw Antimass, but it also front-loads Contraband and Exotic patterns you'll need later for high-tier upgrade crafting.

How Pattern Size Actually Affects Stats

The September devlog spelled out the mechanic but left the math to players, so the pattern-size rule for Mycopunk upgrade crafting in 1.0 is best understood through the three stat interactions detailed below. In practice, every stat a hex pattern rolls is multiplied by its current footprint before being added to your build sheet, meaning a 4-cell pattern in a level-3 upgrade slot can output noticeably higher numbers than the same shape squeezed into a 2-cell slot.

• Footprint scaling — a pattern's physical size on the hex grid is now a hidden stat multiplier. Larger patterns that you place via Boost pull higher numbers from the underlying stat range.

• Compression penalty — if you shrink a large pattern to fit a small grid slot, the roll is normalized back down. The pattern-size rule rewards keeping the footprint intact.

• Surrounding-cell exception — upgrades like Hard-Light Prison or Concussive Wave that read neighbor cells for their numbers are unaffected by the size change. Their effective stat comes from the cells themselves, not the pattern shape.

This is why the Cleanse knob is so powerful: it lets you reroll one stat without paying the size cost of a full Boost. If you have a large pattern and one bad stat line, Cleanse fixes the bad line while keeping the size multiplier intact.

Rarity Tiers and How They Roll

Mycopunk's rarity ladder at 1.0 has eight named tiers, and the way they roll is the second pillar of any serious craft session. The first four — Standard, Rare, Epic, and Exotic — follow a traditional ascending power curve. Exotic+ is a step above Exotic, and Contraband is the rarest of all, dropped only by Ouroboros runs. Oddity is a mid-Ouroboros tier that appears commonly in roguelike rooms. Broken Frame is the failure state: an upgrade that cannot be scrapped and is permanently locked to your inventory until you sell it or accept its negative stat.

Rarity Tier Reference

The table above is the cleanest mental model for the craft loop. Most of a player's Antimass will be spent moving Standard → Rare → Epic → Exotic via Boost. Strange Components then handle the Exotic → Exotic+ push via Turbocharge. Contraband infusion is a separate branch reserved for builds where an Exotic base can accept a Contraband donor.

Level Unlocks for Rarity Slots

The upgrade grid does not expose every rarity tier to every player from the start of a run, so confirmed 1.0 patch data ties each rotation slot to a specific character level milestone that gates which upgrade crafting recipes you can actually roll, fuse, or equip. Hitting these level thresholds is also the best way to level up efficiently, because every node you unlock expands the RNG pool of affixes the crafting bench can offer during mutation refines.

• Standard at level 3

• Rare at level 8

• Epic at level 16

• Exotic+ at level 30

The level-30 cap is hard — once you hit 30, no further XP is earned, and the Exotic+ slot is the final grid slot a player can access. This makes the level 25-30 stretch the natural window for pushing any build into its final form. Players who want a deeper breakdown of how XP and levels interlock with the upgrade grid will find a clear progression path in the Mycopunk advanced guide.

Cleanse, Favorite, and the Surgical Approach

Cleanse is the underused lever in 1.0 craft. Most players instinctively use Boost for every problem, but Boost rerolls the whole stat block, which means you can lose a perfect roll chasing a single bad stat. Cleanse exists precisely to avoid that. The mechanic is confirmed by the 1.0 patch notes: a Cleanse rerolls a single stat within its current rarity range and leaves the rest of the upgrade untouched. The cost is small relative to a full Boost, and the result is almost always a smaller variance spread than rerolling the whole pattern.

The two most common patterns a solo player will hit are a near-perfect Rare with one bad stat line, and an Epic with a strong prefix paired with a useless suffix — both cases where a full Boost reroll would throw away more value than it gains, making targeted Cleanse the cheaper and more variance-controlled option for solo craft runs.

• A near-perfect Rare with one bad stat line. Cleanse fixes the bad line, leaving the strong stats in place.

• An Epic with a great prefix and a useless suffix. Cleanse the suffix while keeping the prefix.

Cleanse is also the right tool when you have an Oddity or a low-rarity pattern with one exceptional stat. Locking the rest of the pattern via the Favorite slot (a separate terminal in the HUB that pins the high end of a stat range) and then Cleansing the one bad line yields a far better result than a full Boost reroll.

Cleanse vs. Boost Decision Tree

Players pushing toward Contraband infusion should keep two Cleanse charges ready at all times, since a Contraband donor pattern almost always has one stat worth Cleansing before it is fused into the base weapon — for example, if the donor rolls a flat +3% Reload Speed where you already cap that breakpoint, spending a Cleanse to reroll that single slot into Elemental Damage or Magazine Size preserves the donor's otherwise excellent two-stat spread and keeps the fusion cost lower than burning a Boost charge on the whole four-slot block.

Turbocharge Spending: What Strange Components Buy

Strange Components are the secondary currency in the craft loop. They drop from late-game missions, particularly Amalgamation Hunt assignments, and they are spent exclusively on the Turbocharge terminal in the HUB. Turbocharge pushes a roll to the ceiling of its stat range — if an Epic upgrade's crit chance rolls between 8% and 14%, a Turbocharge pins it to 14% on the chosen stat.

The cost of a single Turbocharge is high enough that most solo players will only see one per week of consistent play, and a coordinated four-stack will see two or three. The strategic use of Turbocharge is therefore narrow:

• Anchor an Exotic's signature stat — the one stat that defines the build (e.g. splash radius for a swarm build, or fire rate for a single-target DPS build).

• Rescue a near-miss roll — if an Exotic dropped at the very bottom of its range and you cannot afford to reroll, one Turbocharge pushes it to the top.

• Finalize a build at level 30 — because Strange Components are rare, most players save their charges for the level 25-30 window when the build is "almost" done.

Component Costs and Where to Farm Them

Strange Components are confirmed to drop from Amalgamation Hunt missions, where the 30-second timer on the Amalgamation kill determines whether the high-tier reward is paid out. The component itself has not been given an exact drop-rate number by the developer — the only confirmed fact is that the timer exists and that failure to meet it forfeits the top reward bracket. The level-30 cap and the Exotic+ unlock create a natural bracket where saving Strange Components pays off.

Players who want a structured plan for hitting level 30 efficiently can pair this guide with the Mycopunk how to level up weapons reference. The interplay between weapon XP, employee XP, and the upgrade grid is one of the most common points of confusion for new crews, and treating the three as separate but parallel ladders is the cleanest mental model.

Solo Play and the Upgrade Crafting Loop

Solo players hit a different craft loop than a co-op four-stack. Because Antimass scales roughly with squad size on high-threat missions, a solo player will need more sessions to reach the same crafting depth. The trade-off is that a solo player has full control over every Boost and Cleanse decision without needing to coordinate grid layouts across the squad. For new crews asking whether Mycopunk is playable solo, the official store page confirms that all missions can be completed solo, with the 1.0 HUB reworked specifically to give solo players more downtime to manage their inventory.

Solo Crafting Loop vs. Co-op Crafting Loop

The Solo Routine

The most efficient solo pattern at 1.0 is to spend roughly 70% of crafting time on Cleanse and Favorite, 20% on Boost, and 10% on saving Strange Components for Turbocharge. Boost is the most visible action but the least efficient per Antimass. Cleanse is cheap, repeatable, and almost always a net positive. Favorite locks the high end of a stat range, so combining a Favorite lock with a Cleanse reroll is the highest expected-value move in the game.

For solo players asking how long a typical play session lasts, the answer depends heavily on mission choice. A short Ouroboros Blitz — confirmed as a 13-room variant in the 1.0 patch — runs 25-35 minutes for a solo player. A full Incursion can run 45-60 minutes depending on how many side objectives the player picks up. Escalations vary widely; an Oxythane Breach is shorter than a Population Control assignment.

Frequently Asked Questions

What is the single most important rule of the Mycopunk upgrade crafting guide in 1.0?

The single most important rule is the September 2026 devlog's pattern-size rule: most upgrade stats scale with the physical size of the pattern placed via Boost, so shrinking a large pattern to fit a small slot effectively nerfs it. The exception is upgrades whose numbers read from neighbor cells — those ignore pattern size. This rule governs every Cleanse, Boost, and Contraband decision a player makes.

When should a player use Boost instead of Cleanse?

Boost is the right tool when the upgrade has multiple mediocre stats and the player wants to chase a higher rarity ceiling. Cleanse is the right tool when one stat is bad and the rest are good. As a rule of thumb, if the upgrade has two or more bad stats, Boost will probably outperform Cleanse in the long run. If only one stat is bad, Cleanse is almost always cheaper and more reliable.

How does a solo player chase Contraband patterns efficiently?

A solo player should run Ouroboros Blitz — confirmed in the 1.0 patch as a 13-room short variant — for Contraband access without committing to a full-length Ouroboros run. The shorter format lets a solo player attempt the run multiple times in one session, which compounds the expected Contraband drop without requiring squad coordination. The developer has not published an exact Contraband drop rate, so the loop is fundamentally time-gated rather than skill-gated.

How long does a typical Mycopunk solo run take, and what is the fastest way to level up?

A solo Mycopunk session runs anywhere from 25 minutes (a short Ouroboros Blitz) to 60 minutes (a full Incursion with side objectives). The fastest way to level up is to chain Escalation and Amalgamation Hunt missions because they pay out the densest XP and Antimass per minute. Pairing that XP grind with disciplined Cleanse-over-Boost use at the HUB is the most efficient solo progression loop available in 1.0.

Is upgrade crafting viable without Strange Components, or are they required to finish a build?

Strange Components are not strictly required to finish a build, but they are the only way to push a roll to the top of its stat range via Turbocharge. A player who runs only Boost and Cleanse can still reach the Exotic tier and achieve a viable build — they just cannot pin the ceiling of any stat. Most solo players will see their first Strange Component drop within a week of consistent play, and the developer has confirmed that Amalgamation Hunt missions are the most reliable source.
