Arknights Endfield Whale’s Guide – How to Optimize High-Spend Accounts

High-spend accounts in Arknights: Endfield are best optimized by locking in all long-term value products first (passes, early bundles), then building a structured plan around 120-pull limited sparks, weapon pity cycles, and base progression rather than impulse rolling. The goal is full comfort and collection while still respecting the game’s pity math.

1. What Whales Should Always Buy First

Community spending breakdowns agree there is a fixed “core package” that every high spender should keep active.​

• Monthly Pass (subscription):
  • Gives upfront Origeometry plus daily Oroberyl and Emergency Sanity Boosters for 30 days.​
  • Consistently ranked as top value per dollar due to long-term premium income and extra stamina.
• Mid-tier Protocol Pass (Battle Pass):
  • Unlocks extra track with a 6★ weapon, more premium currency, and high-end mats; rated “high efficiency.”​
  • Perfect baseline even for moderate spenders, and still efficient for whales.
• High-tier Protocol Pass (Advanced Supply):
  • Adds breakthrough items for 6★ weapons; raw currency value is worse, but it’s designed for whales who want maxed signatures and collection.
• Early “Grand Vision” / starter bundles:
  • Launch bundles that include a 6★ weapon plus Origeometry at a discount are flagged as very good if you already plan to spend heavily.​

Anchor rule: Monthly Pass + mid-tier Protocol every version, high-tier and starter bundles on top if you care about fully-uncapped weapons and early spike value.​

2. Banner Strategy for Whales – Characters

Whales can realistically secure every limited if they manage pity correctly.

• Exploit global pity and carry-over:
  • 0–80 6★ pity (soft at 65, hard at 80) carries across all character banners, so you never “lose” character pity.
  • Every limited banner has a 120-pull featured guarantee, so a fully committed whale run is 120 pulls for that unit at worst.
• Optimal whale pattern per banner:
  • Start each major limited with at least 120 pulls banked (or confidence you will buy to 120).
  • If you win the coinflip early (featured 6★ before 80):
    • Option A (collector): Keep going until you hit multiple copies or clear the banner’s internal spark goals.
    • Option B (efficient whale): Stop once you get 1–2 copies, save remaining pity for the next limited.
  • If you lose the 50/50 at 80:
    • Push to 120 to force the featured, then decide if you want dupes.
• Dupes vs breadth:
  • Reddit and whale-discussion threads emphasize that Endfield (like Arknights) is not tuned around mandatory dupe stacking; vertical investment is mostly comfort and slight power, not game-breaking.​
  • For meta-focused whales, 1–2 copies of each limited + broad roster often outperforms triple-breaking a single unit.

Result: whales can go for “completionist limited collections” while still being pity-efficient by only hard-committing when there is a 120-spark safety net.

3. Weapon Gacha Optimization

Weapons are the true whale sink; planning matters even if money is no object.

• Arsenal banners and pity:
  • 5★ weapon every 10 pulls, 6★ weapon guaranteed at 40 pulls (25% featured, 75% other 6★s).
  • At 100 pulls, you earn an Arms Offering selector for any non-featured 6★ weapon; at 180 pulls, you are guaranteed the featured 6★ weapon.​
  • After 180, every 80 pulls alternates between Arms Offering and featured weapon.​
  • Weapon pity does not carry between banners.
• Whale-focused pattern:
  • For top favorites: budget 180 pulls per signature to guarantee it.
  • For second-string units: leverage Arms Offering at 100 and later to fill out generic strong weapons instead of chasing every signature on-rate.
  • Always clear Battle Pass weapon first; then use gacha to patch remaining weapon slots.

High spenders aiming for comfort should prioritize weapons that many operators can use (universal stat sticks) before chasing every ultra-niche signature.

4. Account Growth and Stock Bill Spending

Whales can brute-force operators, but base and currency management still gates gear and long-term comfort.

• Stock Bills:
  • Farm via high-value factory lines (e.g., potions) and outpost trade; then buy weekly shop items first.​
  • Priority purchases:
    • Weekly headhunt permits and upgrade materials.
    • Outpost/factory upgrades that increase income.
    • Only later, limited weapons/gear from shops for collection and min-maxing.​
• Gear and AIC:
  • Even for whales, endgame gear and high-tier AIC upgrades eat massive Stock Bills; maximizing production early keeps the account “future-proof.”

Spending money does not replace the need to optimize Stock Bills and AIC, it just lets you hit character/weapon thresholds faster.

5. Comfort, Flex, and Collection Goals

Once the efficient core is set, whales can chase pure comfort and flex targets.

• Comfort goals:
  • Fully-built squads for each element / role combination.
  • Signature weapons plus high-breakthrough on personal favorites.
  • All QoL packs (extra loadouts, skins, cosmetics) that make play smoother and more enjoyable.
• Collection goals:
  • Owning every limited unit at 1+ copies.
  • Using selector milestones (300 standard pulls, Arms Offerings, etc.) to patch missing catalogue pieces.

Community commentary around Arknights whales carries over: the “whale meta” is mostly about comfort, aesthetics, and supporting devs, not about locking F2P out of content with impossible power gaps.

In short: a whale-optimized Endfield account keeps Monthly + Protocol passes always active, secures every key limited at 120 pity, targets high-impact weapons with 180 pity cycles, and builds out factory/Stock Bill income, then spends the rest on comfort, cosmetics, and collection rather than inefficient random pulls.
