Ultimatum Mapping — Catalyst & Inscribed Chain

Strategy A-tier farm Ultimatum bằng cách stack scarab chain Catalysing → Inscription trên map có Empowered Mirage implicit để chạy Ultimatum hai lần mỗi map. Profit core đến từ catalyst pile (slow-sell 25-49c/unit cho Prismatic) và Inscribed Ultimatum rolled-tier lottery — riêng vendor recipe upgrade chain mở cửa cho Mageblood/Headhunter pull khi gặp Life multiplier 200%. Phù hợp character đã có 150k+ EHP và 30+ div thanh khoản để mua scarab batch.

Frontmatter restate: Tier A, investment High, profit 30-50 div/hr, confidence Medium (number triangulate từ stream sample 2026-05-11, chưa personal-test bulk session).

Strategy Overview

Lý do strategy này print currency trong meta Mirage tháng 5/2026 là vì Ultimatum scarab chain stack multiplicatively — Ultimatum Scarab of Catalysing convert tất cả reward sang catalyst, rồi Ultimatum Scarab of Inscription convert catalyst reward đó sang Inscribed Ultimatum . Output đậm catalyst (slow-sell market hold steady tháng này) hoặc Inscribed pile để vendor-recipe upgrade lên tier cao hơn.

Market signal 2026-05-11 confirm meta nóng: Ultimatum Scarab of Catalysing spike +404% week-over-week chạm 288.52c, Awakening Fragment +1406% — top streamer đang đổ vào, supply chưa đuổi kịp demand. Sweet spot là vào trước khi catalyst tier supply flood. Strategy này competing trực tiếp với Harvest Scarab of Doubling setup (xem Harvest Ultimate) — Harvest profit cao hơn (70-85 div/hr) nhưng investment cao hơn và phụ thuộc lifeforce market; Ultimatum chain dễ scale theo budget hơn.

Setup

Atlas Passive Tree

Hai layout sẵn import vào poeplanner — chọn theo build power:

Easy mode (no Grueling Gauntlet) — phù hợp character bình thường, Ultimatum 10 round: poeplanner.com/a/6cUz
Hard mode (Grueling Gauntlet keystone) — character mạnh, +3 round bonus reward tier cao hơn: poeplanner.com/a/6cUH

Path chính lấy hai keystone bắt buộc: 25% chance to duplicate Ultimatum rewards (busted node, mọi expensive drop có 25% chance double) và Ultimatum rewards granted as if you had completed an additional round (skip round 1, đụng reward sớm hơn — synergize với Ultimatum Scarab of Bribing ). Sau đó lấy:

Survive the Assault boost — đẩy chance roll variation dễ nhất (đứng phòng thủ trong vòng tròn). Lower chance roll Conquer the Stones (phải đứng yên trên stone circle, brutal cho mobile build).
Conquer the Stones radius +size — nếu lỡ roll variation này, circle to hơn dễ stand.
Currency Rewards bias — skip unique/divcard reward node vì pool full junk uniques và junk divcards; currency node bias về Divine Orb / Inscribed drop, ROI cao hơn nhiều.
Final boss chance + drop bonus — boss drop full stack random catalyst + Tainted Catalyst + helmet. Boss spawn không guaranteed nếu thiếu node này.
Top-hat Grueling Gauntlet keystone — optional. Thêm 3 round Ultimatum (13 round thay vì 10 default). Reward tier cao hơn ở round muộn, nhưng difficulty leo dốc theo round count. Build mạnh có lợi (extra round = extra reward tier), build yếu phá session.
Ruinous Wager keystone — optional. 50% less Ultimatum damage taken, nhưng apply Ruin stack khi đứng yên. Mobile build (Flame Dash spam, MS 150%+) không cảm thấy downside; stationary build (Cast-on-stand-still RF Chieftain) tránh.
Astrolabe re-roll keystone — Run cùng map base liên tục bằng Chaotic Astrolabe , save thời gian tìm layout.
Mirage blocking nodes — Lock map mod pool về Mirage để 100% map có Empowered Mirage implicit.

Setup này cần ~80-90 atlas point. TheLeader_A 199% MS qualify mobile → keep Ruinous Wager.

Scarabs & Map Device

Setup 5 scarab (map device 3.28 Settlers atlas node expand đủ 5 slot):

Ultimatum Scarab of Bribing ×2 — Mỗi Bribing skip round 1, hai cái stack skip 2 round. Reward valuable hơn ở round muộn, vào thẳng round 3+ saves 30s/Ultimatum. Bonus: massive XP, leveling 100 trong khi farm.
Ultimatum Scarab of Catalysing — Convert toàn bộ Ultimatum reward sang catalyst. Đây là scarab spike 288c (2026-05-11) — đắt nhưng output catalyst stack scale theo map quantity (xem Loot Breakdown).
Ultimatum Scarab of Inscription — Stack trên Catalysing. Catalyst reward bị convert tiếp thành Inscribed Ultimatum, mở khoá tier lottery + vendor recipe pipeline.
Kalguuran Scarab — Lost Shipments side content khi mapping, dust + Mirror Shard chance, không xung đột Ultimatum encounter spawn. Slot này có thể swap cheap fragment nếu thiếu liquid.

Map device fragments không cần cho primary — Mirage implicit map đã trả về 2 Ultimatum encounter per map, đủ payback scarab cost. Budget variant (alternatives section) dùng Sacrifice at Dusk cheap fragment để bypass Catalysing scarab cost.

Map Choice

Jungle Valley layout cực nhỏ, linear walk — Ultimatum encounter spawn trong 30s. Đây là sweet spot khi chạy Astrolabe re-roll: cùng layout, cùng route, muscle memory tối ưu.

Trade search pre-filtered (Mirage league): pathofexile.com/trade/search/Mirage/3q5zgyo5h5 — saved query với Jungle Valley + Empowered Mirage implicit + mod exclude (Cannot Flask Charges / Cannot Block / Less CD Recovery). Bulk buy 20-30 map cùng trip để giảm trade friction.

Atoll alternative — layout open, 85% map roll vào Mirage spawn area, tốt hơn cho catalysing-only variant (skip Inscription scarab → cần Mirage rate cao để compensate). Atoll nặng base monster density hơn Jungle Valley.

Map mod gate bắt buộc:

Tier T14-T16 only — tier thấp hơn drop pool nghèo, không trigger high-tier Inscribed reward.
Implicit: "Area contains an Empowered Mirage covering the entire map" — đây là điều kiện sống còn. Empowered Mirage = run Ultimatum lần 2 trong Mirage overlay, hưởng scarab chain 2 lần per map device click. Không có implicit này thì cost catalysing 288c không pay back.
8-mod corrupted preferred. Map mod quantity ≥108% là minimum gate; combined với atlas quantity wheels push tổng in-game quantity vào breakpoint 150%+ (xem Loot Breakdown math). Yield bậc thang theo total quantity: 2→5→6 catalysts cho Ultimatum tier 1 (base 2).
White map (T14-16, no mods) cũng work — primary scarab chain trả cùng reward bất kể map mod. Juicing chỉ ảnh hưởng catalyst quantity multiplier. Build yếu nên chạy white để safe, build mạnh push 8-mod corrupt cho quantity max.
Filter mod break build trước khi run (xem Build Requirements).

Build Requirements

Min spec để clear Ultimatum wave threshold trong 5-6 phút:

DPS: 3-5M single target. Wave threshold ramp theo round; Bribing skip 2 round nhưng round 7+ vẫn cần burn boss fast.
EHP: 150k+ effective, hoặc CI 6k+ ES với block layer. Ultimatum mods stack — "Monsters deal 50% more damage" + "Monsters have 30% more life" combine = death sentence cho squishy.
Movement skill ngắn CD: Flame Dash, Whirling Blades, Frostblink để né Razor Dance / Volatile Cores.

Mod-aware filter trước mỗi Ultimatum (preview mod ở stone circle popup, walk away nếu roll bad):

"Cannot gain Flask Charges" — #1 deal-breaker cho Mageblood build. Disable hoàn toàn flask uptime → mất Bottled Faith, Quicksilver, mọi defensive flask. Skip ngay, vendor recipe Inscribed nếu cần.
"Cannot Block" — Brick block-stack defense. TheLeader_A 65% block / 75% spell block layer evaporate → EHP đáng kể giảm. Skip.
"Less Cooldown Recovery" — Movement skill + Convocation gãy. Walk away.
"Unlucky Critical Strikes" — Crit-based build mất 50%+ DPS. Walk away nếu DPS phụ thuộc crit.
"No Life / Mana Regeneration" — Sustain build chết. Mageblood + Eldritch Battery có thể compensate.
"Volatile Cores" — DoT khi đứng yên trên stone circle. Force re-position liên tục.

Compatibility check cho TheLeader_A (Witch Necromancer CI Spectre, 27.88M minion DPS, 7987 ES, 65/75% block, 199% MS, Mageblood):

✓ DPS dư thừa, Wretched Defiler spectre clear wave nhanh
✓ CI immune chaos → "Choking Miasma" mod free
✓ 199% MS qualify Ruinous Wager
✓ "Allies cannot die" non-issue — spectre không phải allies của Ultimatum monster
Mageblood-dependent → "Cannot gain Flask Charges" là filter #1, preview mỗi Ultimatum
75% spell block là defensive backbone → "Cannot Block" filter #2

HC viable không? Không khuyến nghị. Ultimatum biến variance lớn — single roll xấu (Cannot Block + Vulnerability + Razor Dance combo) wipe HC character. SC-only strategy.

Gameplay

Mỗi map chia ba phase: setup → main Ultimatum → Mirage overlay Ultimatum. Vào map, dùng movement skill chạm boundary để spawn proc nhanh, để minion/spectre roam side, mục tiêu là Ultimatum altar đầu tiên. Đến altar, preview mod popup, check Cannot Flask Charges / Cannot Block / Less CD Recovery. Nếu roll dirty: log out hoặc skip altar (rare drop nhưng đôi khi worth abandon vs death).

Khi altar clean, place sacrifice nếu có (không bắt buộc cho mapping variant — sacrifice only cho Inscribed doubling loop). Stand giữa stone circle, để spectre/minion clear mob spawn quanh. Pick reward tier cuối mỗi round — ưu tiên "Survive the Assault" variation (passive stand-still), avoid "Conquer the Stones" nếu mobile build (phải chase circle position). Round 7-10 reward tier cao nhất, đừng leave sớm.

Sau khi Ultimatum chính xong, di chuyển đến Mirage zone (Empowered Mirage implicit cover toàn map → Mirage proc trigger trong 30s). Click vào Mirage altar lần 2 — scarab chain re-apply, catalyst/Inscribed reward stack lần nữa. Map end nên có 2 reward pile (main + Mirage overlay).

Pickup style: hover xác định price tier khi pickup, hoặc grab-all + sort cuối map. Catalyst stack thẳng tab; Inscribed Ultimatum sort theo Life multiplier (filter hover stat "X% more Monster Life" ở mod cuối). Tier Inscribed cao (Life 120%+) save cho vendor recipe upgrade pipeline.

Loot Breakdown & Economic Analysis

Math catalyst yield (formula: base × (1 + map_quantity_%/100), capped 10, rounded down — derived stream sample 2026-05-11). Base catalyst per Ultimatum = 2 / 3 / 4 (theo Ultimatum reward tier intern).

<150% total quantity: 4 / 7 / 9 catalysts per Ultimatum (multiplier ~2.49×). Sub-optimal — Catalysing scarab 288c không pay back tốt.
150-199% total quantity: 5 / 7 / 10 catalysts (multiplier 2.5×). Breakpoint chính — đa số map juiced rơi vào range này.
200%+ total quantity: 6 / 9 / 10 catalysts (multiplier 3×, capped 10 ở base 4). Plateau, không scale thêm.

→ Map mod quantity ≥108% là minimum gate (8-mod corrupted với "increased item quantity" mod) — combined với atlas quantity wheels push tổng in-game quantity ≥150%, hit breakpoint trung. Atlas 200%+ + 8-mod corrupted = max yield 6/9/10.

Per-map P&L (đo 2026-05-11, primary variant Catalysing+Inscription):

Investment:
  Map (8-mod corrupted, Empowered Mirage implicit): ~6c
  Ultimatum Scarab of Bribing ×2:                    ~1c
  Ultimatum Scarab of Catalysing:                    ~288c
  Ultimatum Scarab of Inscription:                   ~60c
  Kalguuran Scarab:                                  ~7c
  ─────────────────────────────────────────────────────
  Total setup:                                       ~362c ≈ 0.90 div/map

Output (2 Ultimatums per map via Mirage overlay):
  Inscribed Ultimatums (PRIMARY — chain converts reward
    pool → Inscribed): 2-5/map varied Life% tier         ≈ 1.0-2.5 div/map
  Catalysts (SECONDARY — boss stack drops + atlas
    overlay drops, NOT chain-converted): 5-15 mixed     ≈ 0.5-1.2 div/map
  Raw Divine Orbs (Currency-biased atlas node):
    0.5-2 per map                                       ≈ 0.5-2.0 div/map
  Tainted Catalyst + boss helmet (~50% chance):         ≈ 0.2 div/map
  ─────────────────────────────────────────────────────
  Total output:                                         ≈ 2.2-5.9 div/map

Net profit/map:                                         ≈ 1.3-5.0 div/map
At 10 maps/hr (6 min/map):                              ≈ 13-50 div/hr

Realistic clean session number 2026-05-11: 30-50 div/hr với scarab catalysing 288c và build clear 6 min/map. Stream sample 20 map = 65 div net trong 2hr = 32 div/hr — đại diện trung bình; lucky session pull được Mageblood pull (tier 0 vendor recipe) đẩy lên 80+ div/hr một session, nhưng không reproducible cho EV.

Hidden tier mechanic trên Inscribed (Life multiplier xác định reward pool — tracked qua mod "X% more Monster Life" ở final position):

0% Life = Tier 4 (junk reward) — skip pickup hoặc vendor bulk
30% Life = Tier 3 (low reward, Divine fragment / divcard) — pickup vào vendor pool
70% Life = Tier 2 (Divine Orb stack, decent unique) — keep, vendor recipe target
120% Life = Tier 1 (high-value: Forbidden flesh/flame, multi-divine stack) — keep cao
200% Life = Tier 0 (jackpot: Mageblood , Headhunter , House of Mirrors lottery) — keep cao nhất

Vendor recipe pipeline: 5 Inscribed Ultimatum cùng Life% vendor = 1 Inscribed random của cùng/cao hơn tier. Mix Life% → vendor return lấy lowest tier (rule cứng). Strategy: gom 5 Inscribed 70% Life không bán được → vendor → có chance roll Inscribed 120-200% Life với reward Mageblood. Đây là lottery layer thật sự, không phải side bonus.

Market Context & Risk

Catalysing scarab spike +404% trong 7 ngày trước 2026-05-11 phản ánh top streamer push vào strategy này — supply chưa đuổi kịp. Window tốt: mua scarab batch 20-30 cái 1 trade trip, lock price 280-290c trước khi spike tiếp. Awakening Fragment +1406% là collateral (final boss fragment) — không cần cho primary, nhưng tín hiệu chứng minh Ultimatum economy đang bullish toàn thị trường.

Saturation risk: catalyst supply scale với số người chạy strategy. Prismatic catalyst hiện 25-49c slow-sell — sau 2 tuần nếu meta hold, supply flood có thể đẩy về 15-20c. Watch poe.ninja catalyst tab tuần này, sell ngay khi spot price giảm dưới 20c (signal flooding).

Patch nerf risk: GGG có history nerf Ultimatum scarab giữa league (3.21, 3.23 đều bị nerf). Track patch notes weekly — nếu Catalysing scarab effect cắt 30%, strategy chết overnight. Buffer: hold scarab batch nhỏ, không stockpile 100+.

League phase fit: Mid (week 6-8 của Mirage hiện tại). Early league catalyst supply thiếu → giá cao, ROI tốt. Late league (week 12+) catalyst flood, switch sang Harvest Scarab of Doubling chain (Harvest Ultimate) hoặc Delirium overlay variant.

Sustainability honest: Consumable, dependency cao. Scarab + map đều consume; không self-sustain. Cần liquid market — nếu cá nhân account không trade fluid (region thiếu seller), strategy gãy.

Profit Optimization

Lever 1: Map quantity max — Push total in-game quantity ≥200% (base catalyst 2/3/4 scale lên 6/9/10, cap 10 ở tier cao nhất). Yêu cầu 8-mod corrupted + atlas quantity wheels + map mod "increased quantity". Tier 3-4 atlas node investment trả về lớn.

Lever 2: Catalyst slow-sell — Cancel auto-listing 5C/Prismatic. List manual 35-49c/Prismatic, accept 30% slower clear rate, gain 40-50% revenue. Same logic Fertile 16→20c, Unstable 2.4→2.8c. Required: stash tab dedicated, daily 5-10 min relist.

Lever 3: Vendor recipe pipeline — Sort Inscribed theo Life%. 5 Inscribed cùng Life% vendor → 1 random Inscribed của cùng/cao hơn tier. Mix Life% → vendor return tier thấp nhất (rule cứng, không bypass được). Output tier distribution chưa có hard data — Fubgun stream cho thấy "occasionally" pull tier 0 (Mageblood/Headhunter) qua nhiều session, nhưng rate cụ thể chưa quantified. Treat đây là lottery layer, không EV deterministic — đừng đếm pull vào profit/hr.

Lever 4: Side content overlay — Atlas tree expand:

Eldritch altars (chance Divine Orb / divcard like The Nurse, The Patient) — instant content, không add map time.
Heist hideout via Smuggler's Cache — đôi khi drop fully-revealed blueprint (1 div instant sell) hoặc enchanted blueprint (experimental items).
Lab trial side encounter → Offering to the Goddess 2-3 div per drop, 1-2 min trial completion.
Settlers of Kalguur Lost Shipments → dust farm + occasional Mirror Shard.

Lever 5: Bulk scarab buy — Negotiate -10% với liquid seller bulk 20+ Catalysing scarab. 20 scarab × 288c × 10% = ~576c saved = ~1.4 div per 20-map session. Nhỏ nhưng compound theo league length.

Alternatives & Variations

Catalysing-only variant — Drop Ultimatum Scarab of Inscription , giữ Ultimatum Scarab of Catalysing + 2x Bribing + 1 cheap scarab (Invasion 0.5c hoặc fragments). Map choice shift sang Atoll (85% Mirage spawn rate, layout open hơn Jungle Valley). Profit empirical 2026-05-11: 77 div / 20 map / 2hr = 32 div/hr (40 div/hr nếu slow-sell catalyst). Consistent hơn primary (RNG Inscribed tier lottery removed), variance thấp. Build kèm reference: CwS Chieftain hybrid magic-find (mobalytics build, endgame PoB). Full breakpoint math spreadsheet: Google Sheet. Phù hợp nếu trade thanh khoản kém hoặc tránh Inscribed price volatility.

Budget Bribing+Dueling variant — Bỏ Catalysing scarab hoàn toàn. Setup: 2x Ultimatum Scarab of Bribing + 1 Ultimatum Scarab of Dueling + 2 cheap fragments. Cost ~6c/map. Output đậm raw Divine Orb + tier 1-2 catalyst drop (không scale quantity). Profit empirical 2026-05-11: 84 div / 8hr / 68 map = 10-11 div/hr, ~1.2 div/map net. Atlas tree planner: poeplanner.com/a/6Jcp. Build reference profile: 180k EHP / 50k armor tanky ele build, poe.ninja. Phù hợp:

Build chưa đạt 3M+ DPS, không scale lên investment cao.
Account thiếu liquid 30+ div upfront.
League start / mid-pivot khi catalyst meta chưa hot.

Inscribed consumption loop — Strategy đối ngẫu: mua Inscribed Ultimatum với reward "Doubles Sacrificed Currency", sacrifice 1 Divine Orb mỗi run trong town. Setup hoàn toàn khác (không mapping, không scarab), profit 18-24 div/hr ở 95% success. Xem Inscribed Currency Doubling. Strategy này consume Inscribed mà strategy hiện tại produce — đôi khi self-supply Inscribed pull được từ mapping rồi quay đầu vào loop sacrifice.

Variant overlay (Delirium combo) — Stack Delirium Scarab of Mania + Catalysing chain ở Tier 17 map cho top-tier streamer. Brutal difficulty, requires mirror-tier build, profit 70+ div/hr nhưng death/log-out risk cao. Không khuyến nghị cho TheLeader_A trừ khi push tier S.

Data & Testing

Profit estimate triangulate từ ba nguồn empirical stream 2026-05-11 + market data poe.watch snapshot 2026-05-11. Chưa run personal bulk session — number reflect độ tin cậy Medium, không High.

Personal test plan trước khi commit 30+ div scarab batch:

Mua 3-5 Ultimatum Scarab of Catalysing + 3-5 Ultimatum Scarab of Inscription + 10 Ultimatum Scarab of Bribing + 5 8-mod Mirage-implicit map (~15 div tổng).
Run 5 maps với TheLeader_A, đo per-map số catalyst pickup + Inscribed drop + raw divine.
Calculate net profit/map vs 0.90 div setup cost.
Nếu ≥1.5 div/map net (≥17 div/hr ở 10 maps/hr) → bulk buy 20 Catalysing + 20 Inscription, commit session.
Nếu <1.0 div/map net → fallback budget variant (Bribing+Dueling) hoặc switch Harvest.

Market data recency: prices fluctuate hàng ngày. Re-check Ultimatum Scarab of Catalysing spot mỗi 24h, nếu >350c thì scarab inflation pricing out strategy — pause, đợi correction.

Source map quantity math: empirical 20-map sample stream 2026-05-11 — base catalyst 2/3/4 multiplied by (1 + map_quantity_pct/100), capped 10, rounded down. Confirm in-game test khuyến nghị trước khi rely full math.

Summary

Primary chain Ultimatum Scarab of Catalysing + Ultimatum Scarab of Inscription + 2x Ultimatum Scarab of Bribing trên 8-mod Jungle Valley/Atoll với Empowered Mirage implicit map → 2 Ultimatums per map device click → 30-50 div/hr ở 10 maps/hr.
Map quantity 150%+ critical breakpoint (2→5 catalysts/Ultimatum); push 200%+ tối ưu (→ 6 catalysts).
Hidden tier Inscribed mechanic — Life% multiplier 0/30/70/120/200% map về reward tier 4/3/2/1/0. Vendor recipe 5 cùng Life% → 1 same/higher tier, lottery cho Mageblood pull.
Mod filter #1 "Cannot gain Flask Charges" (kill Mageblood), #2 "Cannot Block" (kill block stack). Preview mỗi Ultimatum altar, walk away nếu dirty.
Catalysing-only variant (Atoll, no Inscription) = 32 div/hr more consistent; budget Bribing+Dueling = 10-11 div/hr ở ~6c/map cho low-budget account.
