Black Market items — full reference

Rule of thumb. BM items are unrepairable. Once durability hits 0, the item is destroyed and the standard component you replaced returns to active. Price reflects the trade-off — you're paying for a temporarily better stat. Negative affixes can drop the price below the standard component's price.

Rarity tiers

The in-game info popup highlights the visible difference: how many affixes the item carries. The tier also shapes the price you pay, how dramatically each affix rolls, and how often negatives slip in — but those don't appear on a number line you can read in-app.

Rarity	Affixes	Price	Roll spread	Negative risk
Silver	1	Baseline	Tight	Moderate
Gold	2	Noticeably higher	Wider	Lowest
Exotic	3	Highest	Extreme	Highest

Two non-obvious things to keep in mind:

Exotic is the gamble, not the upgrade. The roll spread is dramatically wider, which means a perfect Exotic blows past anything Silver or Gold can produce — but the same width applies to negatives. Negative chance is also higher at Exotic than at Gold.
Gold is the cleanest tier risk-wise. Lower negative chance than both Silver and Exotic, two affix slots for build flexibility. It's the workhorse tier; Exotic is the high-stakes bet.

Special markers in the shop

When browsing the BM shop, watch for these icons on item cards:

★ Perfect roll — the top affix value (≥ 90 % of the max possible roll). Premium price tag attached. These are the items worth saving Cu for.
🧬 Mutated — the item's base stats (VRAM / RAM / storage / steps per second) are randomly perturbed at generation time. Always a premium tag, but the perturbation can be either favorable or unfavorable — read the stat line.
◆ Cross-type affix — an affix from a different component category landed on this item (e.g. an HDD with a GPU-style -frustration perk). Wider effect coverage from a single slot.
● BM exclusive — only obtainable via the Black Market. See the BM-exclusive section below for the full list.

Affix colors

● positive (green) — beneficial effect.
● negative (red) — drawback (often paired with positives on the same item).

Durability classes

Every BM item already lasts about twice as long as the equivalent standard component — that's what the "BM items are UNREPAIRABLE — but they last 2× longer than standard HW!" notice in the shop is referring to. The durability class then nudges that baseline up or down, and trades it against stat ceiling in the opposite direction:

Class	Stat ceiling	Lifespan
Fragile	Highest — glass cannon	Shortest (still longer than a standard part, just barely)
Balanced	Baseline	Standard — the typical BM roll, comfortably above a non-BM part
Tough	Lower than baseline	Longest

Balanced is the most common roll. Fragile and Tough are the rarer ends — pick deliberately.

Combined with the rarity roll spread, a Fragile Exotic can hit absurd peak stat values but burns through faster. Tough Gold is the workhorse — steady stats, longest lifespan, easy to justify. Balanced anything is the safe default when you just want a reliable upgrade.

Affix catalog — Positive

GPU

Overclocked — +10–25 % tok/s
Lucky — +5–15 % Ru
VRAM Boost (Gold+, gate-breaking) — +1–4 VRAM (flat)
Calm Core — −5–25 % frustration
Ergonomic — −5–25 % exhaustion

RAM

Extra Slots (Gold+, gate-breaking) — +1–3 module slots (flat)
Ru Generator — +8–20 % Ru
Overclock — +5–15 % learning
Zen Mode — −5–25 % frustration
Comfort — −5–25 % exhaustion

HDD

Domain Master (Gold+, gate-breaking) — +1–2 domain slots (flat)
Scholar — +5–15 % learning
Data Cache — +5–12 % Ru
Organized — −5–25 % frustration
Defragmented — −5–25 % exhaustion

Cooling

Turbo — +10–25 % steps/click
Liquid Flow — +10–25 % steps/sec
Chill — −10–25 % frustration
Cool Breeze — −10–25 % exhaustion

What "gate-breaking" means. A gate-breaking affix can push a stat above the standard component's hard ceiling — e.g. Extra Slots on RAM lets you exceed the chassis's module slot cap. Gate-breakers never appear below Gold rarity and have lower drop weights.

Affix catalog — Negative

Often paired with positives on the same item — the negative is why you're getting the positive at a "good" price.

GPU

Unstable — +2–5 % frustration per run
Power Hungry — +2–5 % exhaustion per run
Noisy — −5–10 % Ru

RAM

Leaky (Gold+, gate-breaking) — −1 module slot (flat)
Slow — −5–10 % learning
Noisy (RAM variant) — +1–3 % frustration per run
Draining — +1–3 % exhaustion per run

HDD

Corrupted (Gold+, gate-breaking) — −1 domain slot (flat)
Fragmented — −5–15 % mastery gain
Laggy — +2–5 % frustration on every domain switch
Heat Sink (misleading name — it's a negative) — +1–3 % exhaustion per run

Cooling

Loud — +2–5 % exhaustion per run
Inefficient — +10–20 % frustration growth rate
Throttled — −5–10 % tok/s when running hot

All types — rare

Silence — disables MONOLOG, DIALOG, and CHAT modules entirely while equipped. Heavy debuff, low drop weight. Avoid unless you're stacking pure-numbers builds.

BM-exclusive affixes (● marker)

These appear only on BM items — you cannot roll them on standard HW.

Quantum (GPU) — ±20 % tok/s per run (variance, not a fixed bonus). Sometimes amazing, sometimes a disaster. Good for risk-tolerant grinding.
Overheated (GPU) — 10 % chance per run to gain +1 % frustration. Manageable cost on long runs, brutal on short.
Neuromorphic (RAM) — +10–25 % brain learning. Cleanest of the four — straight upside, no condition.
Experimental Liquid (Cooling) — boosts steps/click significantly but takes a 5 % instant durability hit at run start. Excellent for short bursts, terrible for endurance.

Pricing logic — why two similar items cost differently

Each item's final price is built from four factors stacked on top of the standard component's base price:

Base price of the equivalent standard component.
Rarity premium — Silver charges the baseline, Gold a noticeable bump, Exotic the most.
Durability class — Fragile drops the price, Tough raises it, Balanced sits in the middle.
Affix roll quality — each positive affix pushes the price up, each negative pushes it down, weighted by how strong the roll is. A "perfect" positive is much more expensive than the average one; a heavy negative can offset a positive almost completely.

The whole thing is then clamped to a sensible window — so even a negative-loaded item never drops below a floor of the rarity-adjusted base, and a perfectly-rolled item can't run away into the stratosphere.

The takeaway: a Silver with a single perfect roll can be priced near the top of its range, while a Gold loaded with negatives can come out cheaper than the standard component despite the rarity premium. Don't anchor on rarity alone — read the affix line.

How to think about buying

Early game (Starter chassis) — a single inventory slot. Buy only Tough items with at least one strong positive. You can't afford to burn the slot on a Fragile gamble.
Mid game (Builder / Deep) — 2 to 3 slots. Now you can specialize: one Tough utility piece + a Fragile burst piece for high-quality runs.
Endgame (Cluster) — 4 slots. Stacking gate-breaking affixes (Extra Slots, Domain Master, VRAM Boost) is the path to builds the standard HW can't reach. Exotic becomes viable here because you can afford to lose them.

One last optimization: BM items degrade mainly from quality gain (with a small per-hour floor). At-cap Ru farming runs barely touch them — perfect for stretching the lifespan of a star item.
