ARTIFICING PLANNER
Gear Artificing Solver — Best T4 Fodder Finder
Table of Contents
Artificing is the wall every Arknights: Endfield account hits once its T4 gear lockers fill up on the Global server. The system is generous in one specific way — every enhancement attempt is guaranteed to succeed once the pity counter trips — and brutal in another, because the success rate on each individual roll swings hard depending on whether the fodder you feed in is a Good Match. The difference between rolling a substat at the base rate and rolling it under a Good Match is roughly the gap between thirty and seventy percent, and that gap compounds across every enhancement on every piece of T4 you build.
The Endfield Hub Artificing Planner indexes all 121 T4 gear pieces in the Global server build across 13 Wuling sets and 8 non-set pieces, mirrors the official in-game substat naming (Cryo & Electric DMG Dealt Bonus, Heat & Nature DMG Dealt Bonus, and the rest of the 21 total substat types), and ranks every match by base value first and craft cost second. When two pieces tie at the highest base stat — which happens constantly inside Wuling set families — the cheaper craftable piece is the single Best Pick, the pricier matches are flagged Tied stat · pricier, and anything that does not have a craft formula is tagged Drop-only so you immediately know to farm instead of craft. Jump straight to the planner below, or read on for how the Good Match mechanic, the Wuling Stock Bill economy, and the pity system all feed into the recommendations the tool gives you.
How to Use the Artificing Planner Below
The workflow inside the tool is short. Pick your target T4 piece from the gear selector, pick the substat you plan to upgrade — anything from Cryo DMG Dealt Bonus to CRIT to SP Gain — and read the Best Pick badge on the result row. That badge always points at the cheapest craftable Good Match fodder for that exact target roll, and the planner shows the full craft cost breakdown so you can sanity-check the spend against your current Wuling Stock Bill and component inventory before committing.
If the Best Pick row is followed by entries tagged Tied stat · pricier, skip them — they exist only so you know they are not better, not so you craft them. If the Best Pick itself carries the Drop-only tag, the cheapest legal fodder is not craftable on demand and you are looking at farming runs instead of a Wuling outpost order; cross-reference your drop history on that piece before assuming the run will be quick. Always glance at the pity counter for the substat you are rolling — it tells you the worst-case catalyst count, which scales the actual fodder volume you will burn through.
Find Best Fodder Gear
Select your target gear and substat to find the cheapest Good Match fodder — pieces with a strictly higher base value, the condition that boosts enhancement success rates from ~30-40% to ~60-70%.

Run a target piece through the planner above, copy the Best Pick into your outpost order or your farm list, and the cost side of Artificing is solved for that roll. The rest of this page explains why those recommendations look the way they do — the Good Match mechanic, the Wuling Stock Bill economy, the pity system, and how the solver breaks ties between pieces that look identical on paper but burn very different amounts of resources at the outpost.
Quick Answer
Pick the T4 piece you want to enhance, pick the substat you are rolling, and let the planner scan every other T4 gear in the database for the cheapest piece with a strictly higher base value on that substat. That is the Good Match condition, and it is what flips your enhancement rolls from a ~30–40% per-attempt success rate into the ~60–70% range. The Best Pick badge always points at the lowest Wuling Stock Bill spend that satisfies the match — even when several pieces tie on raw stat value, the cheapest craftable option wins the badge and the more expensive ones get tagged as ties.
Across all 121 T4 pieces, every roll is also backstopped by pity: Dual Stat and Special Stat substats guarantee at 6, 12, and 20 attempts for levels +1, +2, and +3, and Single Stat substats guarantee at 12, 24, and 40 attempts. That means a worst-case max-out on a single substat costs between 38 and 76 Wuling Artificing Catalysts, and the planner's job is to make sure each of those attempts is using the cheapest legal fodder so the bill-side cost stays as low as the catalyst-side cost is fixed.
What Artificing Actually Is in Arknights: Endfield
Artificing is the endgame substat enhancement system for T4 (Tier 4) equipment. Every T4 piece carries three substats, and each of those substats can be enhanced up to three times — the standard +1, +2, +3 progression — by feeding a sacrificial gear piece into the Artificing screen along with one Wuling Artificing Catalyst per attempt. The outcome of each attempt is not deterministic on the first try, but the pity counter is: once you have spent enough catalysts on a single substat, the next attempt is guaranteed to succeed regardless of what came before.
The mechanic that makes Artificing interesting — and the reason a planner exists in the first place — is how the per-attempt success rate is computed. Each roll is either a normal attempt or a Good Match, and Good Matches roughly double the success rate of a normal attempt. That difference is what determines how much of your catalyst budget actually has to lean on the pity guarantee versus succeeding early, and it is decided entirely by what fodder piece you slot in.
One quality-of-life detail that makes this whole system tractable on Global: every piece of equipment with the same name has identical stats. There is no per-drop RNG on substats themselves — the Wuling Bell, for example, is the same Wuling Bell whether it dropped today or three weeks ago. That means the planner can show you exact substat values for every piece in the database, and the Best Pick recommendation never has to hedge "if you got lucky on this drop." If a piece has the right base value on paper, every copy you own or craft has that same value in your inventory.
Why Good Match Decides Every Roll
A Good Match occurs when the sacrificial gear piece has a strictly higher base stat value than the target substat being upgraded. Strictly higher matters — equal values do not qualify. If you are trying to enhance Agility 10 on a target piece, the fodder needs Agility 11 or higher to count, and Agility 10 fodder will fail the check even though it carries the same stat name. The planner does this comparison automatically across the entire 121-piece database every time you change the target substat, so you never have to eyeball whether a row meets the bar.
The reason this matters in practice is that the bar swings depending on which roll you are working on. A fresh +1 enhancement against a low base value is easy to satisfy — half the database qualifies. A +3 enhancement against the highest base value of a stat is the opposite case: only a handful of pieces in the entire game clear the threshold, and several of them are drop-only, which means farming runs rather than crafting. The planner shows you the full shortlist of legal pieces for whichever roll you are on, and the Best Pick badge points at the cheapest of those.
The headline number to remember is the success-rate swing: roughly 30–40% per attempt at the base rate, jumping to ~60–70% under a Good Match. Over the worst-case 6, 12, and 20 attempts that Dual and Special Stats can run for, that swing decides whether you hit the success early and walk away with catalysts left over or grind all the way to the pity ceiling. Stack three substats per piece and three pieces per character and the cumulative impact across a single build is enormous.
The Wuling Stock Bill Economy
The fodder you feed into Artificing has to come from somewhere, and on Global that somewhere is almost always a Wuling outpost. T4 gear is crafted with Wuling Stock Bills as the primary currency, paired with one of three script-tier components depending on the recipe. The script tiers are Xiranite Component for 8,000-coupon recipes, Cuprium Component for 16,000-coupon recipes, and Hetonite Component for 25,000-coupon recipes, and they progress in scarcity in that order — Hetonite is the rarest of the three and gates the most expensive crafts.
Stock Bills are not just an outflow currency either. Recycling unwanted T4 equipment returns Wuling Stock Bills, the same currency you spend at the outposts to craft more T4 gear. That makes recycling the natural way to fund the cheapest fodder picks the planner recommends — pieces with stat lines you do not need on any of your current targets are higher-yield as Stock Bill refunds than they are sitting in your locker. Treat your locker as a working capital pool, not a museum, and the per-character build cost drops noticeably.
The reason the planner sorts on craft cost at all is that the same target substat is often satisfied by several different pieces, each with wildly different bill plus component tier costs. Two pieces can tie at the exact same Agility base value while one of them needs Hetonite Components and the other needs only Xiranite. Both pieces clear the Good Match condition identically, but one of them costs roughly three times what the other costs in raw resource terms. The planner is built to make that gap impossible to miss.
How the Best Pick Finder Solves Ties
Internally, the Best Pick Finder works as a gear artificing solver: pick a target T4 piece and a substat, and the engine scans every T4 gear in the database to find pieces that satisfy the strict Good Match condition. Those candidates are then ranked first by base value and second by craft cost. The base-value sort puts the highest-stat fodder at the top — which is what you want, because higher base values keep your fodder useful for higher target rolls down the line — and the craft-cost sort breaks ties among pieces that tie on raw stat value.
Among gears tied at the highest stat value, the cheapest craftable piece is the single Best Pick, and that single piece is what the badge points at. Pricier matches at the same stat value get the Tied stat · pricier tag, which is the planner's way of saying "this would also work, but you are throwing Hetonite or Cuprium at a problem that Xiranite already solves." Any piece without a craft formula gets the Drop-only tag, so you know to farm instead of craft when that is the only legal option — or to skip it in favour of a craftable alternative one row down.
The same solver also powers the Matrix View. Where the Best Pick gives you the single cheapest fodder for one target roll, the Matrix View surfaces the highest-value piece per (substat × set) combination across the entire 121-piece database. That is the planning view — useful when you are deciding which characters to build next and want to see at a glance which sets have the deepest substat coverage. The pair of views together is what lets you plan an entire build without flipping between spreadsheets and the in-game Artificing screen.
Pity, Catalysts & the Worst-Case Budget
Every enhancement attempt costs one Wuling Artificing Catalyst, and the pity system guarantees a success after a fixed number of attempts on the same substat. Dual Stat and Special Stat substats guarantee at 6, 12, and 20 attempts for levels +1, +2, and +3 respectively, which means a fully maxed Dual or Special substat costs at most 38 catalysts even in the worst-case streak where every non-guaranteed attempt fails. Single Stat substats are harsher: pity hits at 12, 24, and 40 attempts, for a worst-case 76 catalysts.
Those two numbers — 38 and 76 catalysts — bracket the maximum catalyst cost of any single substat on any single piece of T4. They are also the numbers that should anchor every budget conversation. A character running three T4 pieces with three substats each has nine substat slots in total, and even half of those at worst-case pity already represents a meaningful catalyst stockpile. Prioritise the substats that matter most for the build before committing the rest, and the math works in your favour; spread your catalyst spend evenly across every substat on every piece and you will run dry well before any of them hit +3.
The planner's interaction with pity is that every Best Pick recommendation assumes you will eventually hit pity in the worst case — the cost optimisation is about minimising the per-attempt bill cost across that worst-case attempt count, not about gambling on a hot streak. Cross-reference the pity table against your current catalyst inventory before starting any rotation, and the planner's Best Pick column tells you which fodder lines to keep in the depot to cover the run.
Stat Priorities by Character Role
Which substats you prioritise depends on what role the character plays in your team. DPS operators benefit most from Physical DMG, CRIT, and ATK% as their core multipliers, with the elemental DMG Dealt Bonus stats — Cryo, Electric, Heat, and Nature DMG Dealt Bonus — taking over for character kits that lean on a single element. Supports flip the priority entirely: Healing for sustain operators and SP Gain for utility operators who need their kit cycling at specific rotation breakpoints.
The 21 substat types in the planner cover all of these roles plus the niche stats that only matter in specific team compositions. Filter the gear list by your priority stats first, then read the Best Pick column for each — that order is faster than scanning the full database top to bottom, and it is what cuts the actual farming time per character. The planner's role-agnostic ranking still applies inside the filtered view: highest base value first, cheapest craft cost as the tiebreaker.
One thing worth keeping in mind before any of this: set bonuses come first. The two-piece and three-piece bonuses on most Wuling sets contribute more to a character's effective output than any individual substat enhancement, and that means securing a complete set is worth more than rolling a single substat from +2 to +3 on a mismatched piece. Get the set live, then turn the planner loose on each substat — that ordering keeps your catalyst spend pointed at the right pieces from the start.
Bookmarks for Active Builds
The star button next to the target gear selector saves a piece to your personal bookmark list. It is built for one specific workflow: jumping between the small handful of T4 pieces you are actively building for current characters without re-searching the database every time. Bookmarked pieces appear as chips in the My Bookmarks panel above the planner — click a chip to load it into the planner, or click the × to remove it.
Bookmarks are stored in your browser's localStorage only. They are not tied to an account, they do not sync across devices, and there is no cloud backup. Clearing your browser data, using "Clear cookies and site data" for this site, browsing in incognito or private mode, or switching to a different browser or device will wipe them. That is fine for the common case — a few pieces you are actively building — but it is worth knowing before you build a long shopping list that you are counting on persisting.
If you do build a long bookmark list, screenshot it before doing any browser cleanup. There is nothing the site can do to recover localStorage that the browser has cleared, and the recovery path is rebuilding the list from scratch by searching the gear database again. For most players this never comes up; for power users with deep build pipelines it is a one-minute precaution that saves a real annoyance later.
