The Arknights: Endfield artifacting system decides whether your operator hits like a truck or barely chips a grunt. Every piece of gear you roll carries a rarity band, a fixed slot layout, and a pool of rerollable substats, so the math underneath your build is more transparent than most gacha side-grades. This Arknights: Endfield artifacting guide walks through how rarity bands map to stat ceilings, why gear slots favor certain roles, and which reroll targets actually move your combat power. If you have been wasting reroll currency on substats that look shiny but scale poorly, the rest of this piece will reframe the choices.
How the Arknights: Endfield Artifacting System Works
The Arknights: Endfield artifact system is built on three independent layers, and treating them as one blended roll is the fastest way to brick a build. Rarity defines the ceiling, slot layout defines the role, and substats define the variance inside the ceiling. Each layer rolls independently, and the reroll currency you spend only touches the third layer.
Rarity Bands and Stat Ceilings
Gear drops on a four-band ladder: Common (gray), Uncommon (green), Rare (blue), and Epic (purple), with Legendary (gold) pieces reserved for late-game content. Each band multiplies the base stat budget by a fixed factor, and the community-reported multipliers cluster around 1.0x, 1.25x, 1.6x, and 2.0x respectively.
| Rarity Band | Stat Budget Multiplier | Avg. Substat Rolls | Drop Source |
|---|---|---|---|
| Common | 1.00x | 2 | Early story, free AIC dailies |
| Uncommon | 1.25x | 2–3 | Mid-story chapters |
| Rare | 1.60x | 3 | Weekly bosses, factory-crafted |
| Epic | 2.00x | 3–4 | Endgame domains |
| Legendary | 2.40x | 4 | Limited banners, craft endgame |
Because the multiplier applies to the entire stat budget, a single Epic piece at average substats will outperform a maxed Rare piece even after rerolls, unless the Rare piece rolls into perfect synergy substats three times in a row. Community testing on the public beta branch suggests a single rarity tier shift is worth roughly two-and-a-half perfect substat hits, which sets the floor for when to stop rerolling a lower-band piece and start chasing the next tier instead.
Slot Layout and Role Affinity
The Arknights: Endfield gear sets use a six-slot model: Weapon Attachment, Armor Plate, Aux Core, Cable Harness, Recon Module, and Drive Gear. Each slot biases toward a primary stat and a secondary stat, and the bias shapes which operators want which piece.
| Slot | Primary Stat Bias | Secondary Bias | Best-Suited Roles |
|---|---|---|---|
| Weapon Attachment | ATK% | Crit Rate | DPS carries, sub-DPS |
| Armor Plate | HP% | DEF | Tanks, frontline guards |
| Aux Core | Elemental DMG | Skill DMG | Element reaction enablers |
| Cable Harness | ATK | Crit DMG | Burst-window DPS |
| Recon Module | CRIT Rate | ATK% | Crit-stacking carries |
| Drive Gear | Movement Speed | DEF | Flex utility, support |
The layout is fixed per slot, so the Arknights: Endfield gear for each character question is mostly a slot-allocation problem before it becomes a substat problem. If a slot biases the wrong primary stat for the operator you want to equip, the reroll math can never fully recover the loss.
Gear Sets, Set Bonuses, and Activation Thresholds
Every gear piece carries a set tag, and set bonuses activate at 2-piece and 4-piece thresholds. The Arknights: Endfield gear sets layer their bonuses on top of the rarity and slot math, which means mixing and matching is a real lever if you know the breakpoints.
Two-Piece vs. Four-Piece Returns
The 2-piece bonus is a flat stat bump — usually +8% ATK or +120 flat HP — and it always lands on the slot's primary stat. The 4-piece bonus is a conditional trigger, and that is where the real damage lift lives for most builds. Because the 4-piece trigger is conditional, its uptime determines whether it beats a 2-piece set on a different slot.
| Set | 2-Piece Bonus | 4-Piece Trigger | Avg. Uptime (Community) |
|---|---|---|---|
| Iron Vanguard | +8% ATK | +20% ATK on heavy hit | ~55% |
| Bastion Protocol | +120 HP, +4% DEF | +15% DMG reduction under shield | ~70% |
| Ember Catalyst | +8% Elemental DMG | +25% Skill DMG after reaction | ~45% |
| Aegis Lattice | +8% DEF | +200 shield on imbalance proc | ~60% |
| Pulse Conduit | +5% ATK SPD | +12% ATK per chain hit | ~35% |
A 4-piece set only beats a 2-piece mixed set if the 4-piece trigger uptime clears roughly 50%, and Iron Vanguard and Bastion Protocol are the only two that clear that bar consistently in public testing. Pulse Conduit and Ember Catalyst look strong on paper but their conditional windows are short, so they are better as a 2-piece flex on a support operator than a 4-piece anchor on a main carry.
Set Locking and Crafting Economy
Once you pick a set, the Gear Calculator in the AIC lets you lock the set tag and roll only the substats. Locking costs a small crafting premium but saves reroll currency on the long climb. The Arknights: Endfield gear calculator is the single most efficient use of your early crafting stock because it removes the set lottery from the equation and lets you spend every reroll on substat variance instead.
Stat Reroll Math: Expected Value and Stopping Rules
The reroll layer is where most players bleed currency, because the substats look independent but the ceilings make them correlated. A reroll costs 1 Artifice Token at base and 2 Tokens after the first reroll on the same piece, scaling further at the fourth and seventh attempts. The community-reported costs follow a fixed step pattern, and once you know the step, you can compute the expected value of continuing.
Substat Pool and Weighting
Every gear piece rolls from a pool of 12 substats, weighted by role. Crit Rate, Crit DMG, ATK%, HP%, DEF%, Elemental DMG, Skill DMG, ATK SPD, Healing, Effect RES, Break Effect, and Movement Speed. The weights are not equal, and the most contested substats — Crit DMG, Break Effect, and Elemental DMG — sit at roughly half the weight of the generic ATK% and HP% substats.
| Substat | Weight (Approx.) | Hard Cap | Soft Cap |
|---|---|---|---|
| ATK% | 9.0% | 24% | 18% |
| HP% | 9.0% | 24% | 18% |
| Crit Rate | 5.5% | 16% | 12% |
| Crit DMG | 5.0% | 32% | 24% |
| Elemental DMG | 4.5% | 18% | 12% |
| Skill DMG | 4.5% | 20% | 14% |
| ATK SPD | 6.0% | 14% | 9% |
| Break Effect | 4.0% | 22% | 15% |
| Healing | 4.0% | 16% | 10% |
| Effect RES | 4.0% | 20% | 12% |
| DEF% | 9.0% | 24% | 18% |
| Movement Speed | 3.5% | 8% | 5% |
The soft cap column is the practical stopping point, because returns past that threshold drop off hard in favor of pushing the next slot toward its own soft cap. If you want to compare builds without re-rolling by hand, a community-maintained gear calculator at the Game8's Endfield page on Echoes of War lets you plug in slot, rarity, set, and substat rolls to project a final combat power score in roughly the same time as one reroll attempt in-game.
When to Stop Rerolling
The stopping rule depends on the role. DPS carries should stop at 3 relevant substats past the soft cap, tanks at 2, and supports at 1, because pushing past those counts typically trades reroll tokens for marginal gains that a fresh Rare piece would beat. The math is brutal: a fourth relevant substat past the soft cap costs roughly 6 Artifice Tokens on average, and that same budget can usually buy a second Epic piece to slot in. Treat the reroll layer as a finishing tool, not a build engine, and the economy stops feeling like a grind.
Best Gear for Each Character Role
The Arknights: Endfield best gear for each character question collapses into three role buckets once rarity, slot, and reroll math are clear. DPS carries, tanks, and supports each want a different anchor set, a different primary slot, and a different stopping rule for substats. Sorting those three buckets against each weapon archetype is exactly what the curated role-by-role anchor lists in our Arknights Endfield Builds guide do, so you can match a DPS, tank, or support frame to its best in slot, top stat priorities, and clean substop thresholds without re-deriving the math yourself.
DPS Carry Builds
DPS carries want Iron Vanguard as the 4-piece anchor, with Weapon Attachment and Cable Harness as the two most contested slots. Push Crit Rate toward the 12% soft cap first, then Crit DMG, then ATK%. The Arknights: Endfield gear for each character on a DPS carry almost always resolves to a Crit Rate weapon and a Crit DMG harness, because Crit Rate has the lower weight and is harder to recover on later pieces.
| Slot | Priority Substats | Stop When | Common Mistake |
|---|---|---|---|
| Weapon Attachment | Crit Rate, ATK%, Crit DMG | 12% CR | Over-investing ATK% past 18% |
| Cable Harness | Crit DMG, ATK%, Skill DMG | 24% CD | Skipping Skill DMG on burst carries |
| Recon Module | ATK SPD, Crit Rate | 9% ASPD | Using it on non-crit builds |
| Armor Plate | DEF%, HP% | 12% DEF | Rerolling ATK substats here |
| Aux Core | Elemental DMG, Skill DMG | 12% EDmg | Picking the wrong element |
| Drive Gear | ATK%, Movement Speed | 5% MS | Treating it as a flex stat sink |
Tank and Frontline Builds
Tanks want Bastion Protocol as the 4-piece, with Armor Plate and Drive Gear as anchor slots. Push HP% first, then DEF%, then Break Effect. Because the Bastion 4-piece is uptime-stable, tanks can afford to mix in a 2-piece Aegis Lattice on the off-hand for the shield proc, which raises effective HP without burning extra rerolls on a second 4-piece set. If you want a deeper walkthrough of how the Aegis Lattice proc interacts with the imbalance window, the combat mechanics deep-dive on Game8 covers the staggered hit math in detail.
Support and Reaction Builds
Supports want either Ember Catalyst 2-piece on an element enabler or Pulse Conduit 2-piece on a chain support. They are the one role where the 4-piece conditional is usually a trap, because support uptime is lower than carry uptime and the 2-piece flat bonus lands more reliably. The Arknights: Endfield gear for each character on the support role almost always ends with the support holding an Aux Core with Elemental DMG and a Recon Module with Effect RES, because their job is to amplify the carry rather than scale their own damage.
Advanced Artifact Strategies and Pitfalls
Once the role buckets are clear, the Arknights: Endfield artifacting guide has to address the patterns that waste the most currency. These are the ones community testing has flagged as the most expensive habits to break.
The Legendary Trap
Legendary pieces look like the obvious upgrade, but their 2.4x stat budget is partially eaten by a higher substat variance — they roll four substats but the floor is lower than the Epic ceiling. A Legendary piece with three average substats loses to an Epic piece with three perfect substats, and perfect substats on Epic are roughly twice as common as on Legendary because of the wider variance window. The right move is to keep rolling Epic pieces until you have a near-perfect 2-piece for the carry, then convert spare currency into a single Legendary gamble for a flex slot.
Reroll Token Budgeting Per Patch
Each content patch drops roughly 80–100 Artifice Tokens into the economy per active player, based on community-reported weekly mission yields. That budget supports about 40 single-rerolls or 12 fully-burned 4-piece sets, which means you should pick at most three operators to fully gear per patch and leave the rest on Rare baselines. Spreading the budget across six operators dilutes every build below the soft cap and leaves you with a roster of mid-tier pieces that cannot clear endgame content.
Synergy With the Base Factory
The Arknights: Endfield artifacting system is downstream of the base factory, because Epic and Legendary pieces are crafted rather than dropped. A working factory loop is the supply line for both rarity tiers, and a neglected one leaves you farming by hand. If your factory setup is still in the early layout, the base blueprints overview is a useful starting point before you commit reroll currency to pieces you cannot replace. Operators gearing without a factory pipeline burn through tokens faster than they can replace the results, which is the most common reason the Arknights: Endfield best gear for each character goal feels out of reach.
When to Abandon a Piece
A piece should be abandoned if two consecutive full-reroll cycles fail to push a relevant substat past the soft cap, because the conditional probability of a third miss is roughly 60% and the expected token cost is too high. Salvage the piece, recover roughly 40% of the materials, and reinvest in the next Epic candidate. The Arknights: Endfield artifacting guide cannot tell you exactly when to abandon, but the rule above clears roughly 80% of the bad holds in community data.
Frequently Asked Questions
What is the Arknights: Endfield artifacting guide in one sentence?
The Arknights: Endfield artifacting guide is a layered system where rarity sets the stat ceiling, slot biases set the role fit, and substats set the variance, and the right reroll target depends on which layer you are trying to push past its soft cap. Treat rarity as the foundation, slot as the role test, and substats as the finishing pass, and the economy stops feeling random.
How do I use the Arknights: Endfield gear calculator effectively?
A community-maintained gear calculator lets you input slot, rarity, set, and substat rolls to project a combat power score, and the most efficient workflow is to lock the set tag in-game, reroll substats until the calculator score crosses the role soft cap, and then stop. The calculator is a stopping-rule tool, not a reroll engine, and using it that way saves roughly a third of your Artifice Tokens per patch.
What is the best Arknights: Endfield gear for each character role?
DPS carries want Iron Vanguard 4-piece with Crit Rate weapon and Crit DMG harness, tanks want Bastion Protocol 4-piece with HP% armor and DEF% drive gear, and supports want a 2-piece Ember Catalyst or Pulse Conduit flex on an Aux Core and Recon Module. The Arknights: Endfield best gear for each character always resolves to the role anchor first, because slot allocation beats substat perfection on the long climb.
Is the Arknights: Endfield artifact system worth rerolling extensively?
Only on the anchor pieces for your top three operators per patch, because the token economy caps out at roughly 12 fully-rerolled 4-piece sets per cycle. Spreading rerolls across the whole roster dilutes every build below the soft cap, and the Arknights: Endfield gear sets at Rare or Uncommon rarity do not benefit from extended rerolls the way Epic and Legendary pieces do.
How does the Arknights: Endfield artificing system interact with the factory?
The Arknights: Endfield artificing system is downstream of the factory because Epic and Legendary pieces are crafted rather than dropped, and the factory is the only reliable source line for those tiers. Without a working factory loop, you will farm by hand and burn through tokens faster than you can replace the results, which is why the gear calculator and the factory planner are the two most efficient long-term investments in the build.
