Arknights Endfield Resource Guide
Everything that touches Endfield's economy in one place. How Sanity, Oroberyl, Stock Bills, Activity Points, and T-Creds connect; what to do every day to keep all of them flowing; and how to plan resources around the next limited banner without burning out.
Last updated
TL;DR
- Five resource economies run in parallel: Sanity, Oroberyl, Stock Bills, Activity Points, T-Creds. Neglect any one and progress stalls.
- Sanity is the highest-leverage resource in the early and mid game — see Sanity Optimization.
- 100 Activity Points a day is non-negotiable — rewards don't roll over. See Daily & Weekly.
- Banner planning is a math problem, not a vibe — forecast income against pity cost. See V1.2 Resource Budget.
- F2P front-loads one-time sources: 8,000+ Oroberyl is on the table if you harvest in the first weeks. See F2P Resource Guide.
What are the core Endfield resources?
Endfield has five resource economies that quietly run in parallel, and most "I'm stuck" problems trace back to one of them being neglected:
| Resource | What it does |
|---|---|
| Sanity | The stamina that gates almost every farm. Regenerates passively. The single highest-leverage resource in the early and mid game. |
| Oroberyl | The premium pull currency. Limited supply, banner-paced. Has to be planned against banner releases, not spent ad-hoc. |
| Stock Bills | The gearing currency that funds Artificing, Wuling trades, and most market interactions. |
| Activity Points | The Protocol Pass and daily mission throughput meter. Hit 100 a day, every day. |
| T-Creds | Operator-progression credits. The bottleneck for skill ups and weapon tunes past the early game. |
The rest of this guide walks each of these by the dedicated cluster guide that goes deepest on it.
How do I maximize Sanity?
Sanity is the resource you'll feel most. It regenerates passively and is capped, which means every hour you don't spend it is income lost. The fix isn't "play more" — it's spending what you have on the highest-leverage farms instead of whatever's in front of you. The Sanity Optimization guide works through the priority order in detail.
The common trap: players burn Sanity on essence farming when their character isn't even at the level cap that essence helps. Finish progression layers in order — operator level, then weapon, then essences. The Sanity Optimization guide ranks the spend categories by stage.
Cap = wasted income. Sanity has a hard cap. If you let it sit full overnight, that's regen you'll never recover. If your schedule doesn't allow a same-day spend, use Sanity restoration items to clear the cap before bed — they're net-positive even at zero loss tolerance.
What's the daily and weekly routine?
The fastest way to feel resource-rich in Endfield is to stop missing daily Activity Points. The full step-by-step lives in the Daily & Weekly Guide — every quest that pays out AP, and the order to do them for a sub-15-minute clear. Protocol Pass stacks on top: same AP throughput, larger rewards across the patch.
100 AP daily is non-negotiable. The Protocol Pass is paced around hitting 100 Activity Points every day. Miss a day and you lose the rewards for that day permanently — they don't roll over. If you can only do one thing daily, do this.
How do I plan for the next banner?
Banner planning is mostly a math problem. Forecast your pull income across the banner window, compare to the pull cost of the target operator at hard pity, and decide whether to skip or commit. The V1.2 Resource Budget shows that math worked out concretely for the current patch — use it as a template even if your target patch is different.
The mechanics underneath are covered in the Gacha Guide (rates, banner types, currency conversion) and the Pity System guide (hard vs soft pity, where the 50/50 sits, banner-specific exceptions).
The trap is committing first, forecasting after. It's easy to spend Oroberyl on a banner you "kind of" want, then be short when the unit you actually planned around arrives. Even a rough forecast — current stash plus expected income over the banner window — turns banner FOMO into a budgeting decision.
What's the F2P resource strategy?
F2P play in Endfield is built around two ideas: harvest every one-time source on schedule, and let the daily/weekly income compound. The F2P Resource Guide is the catalog — every free Oroberyl source, how much it pays, and what to do first to maximize the early stash.
The early-game multiplier: one-time sources (story rewards, Operational Manual nodes, achievement tiers) pay out 8,000+ Oroberyl across an account's first weeks. F2P accounts that ignore these in favor of grinding repeatable income end up with significantly fewer pulls at the first major banner. Front-load the one-time sources.
Where does the resource economy connect?
Resources don't sit alone — they fund the rest of the game. Three connections matter most.
1. Factory → Stock Bills → gearing
Most of your gearing budget eventually traces back to AIC throughput. The Factory Guide hubs base building; once you're producing efficiently, Stock Redistribution and Wuling trades convert that throughput into the Stock Bills your gear actually needs.
2. Sanity → progression layers
Sanity feeds the Operator Progression path — levels, weapons, skill mastery — and the Artificing grind for catalysts. The order matters: don't skip ahead to artificing while your operator is still under-leveled.
3. Pulls → roster → endgame access
Banner planning ultimately decides whether your roster can handle the endgame content. A clean budget keeps you on-meta without spending every dollar in your wallet.
