Executive Summary & Global Clairvoyance Timeline

The Annual Anniversary Event (999 Runs) represents the single most lucrative resource milestone in Onmyoji's yearly operational cycle. With the Global server traditionally trailing Mainland China by approximately 3 to 5 weeks, Global Onmyoji players enjoy a decisive *Clairvoyance Advantage*. By examining empirical testing from China's live servers early, players can calculate exact stamina reserves, plan Jade expenditures, and avoid costly resource traps weeks before the event lands.

Crucial Axiom
Core Axioms for the 10th Anniversary Event: 1. Jade Event Tickets (勾玉门票) are a non-negotiable MUST-BUY. The 6★ soul drop rate is more than 2x higher than regular monthly events, with the critical advantage of Custom Soul Selection (御魂自选). 2. Paid Dispatch / Delegation Tickets (勾玉委派) are an inefficient trap for 90% of players. They merely purchase additional stamina burn capacity at a steep premium of 24 AP + 4 Jade per 6★ soul. 3. The Era of Fortune Cat (招财猫) as an Event Custom Pick is OVER. With modern PvE and PvP dominated by high-multiplier souls and non-RNG orb generators, wasting custom slots on a soul farmable every Tuesday in Orochi 10 is a severe opportunity cost blunder.

Empirical Drop Rates & Mathematical Model

The following data is synthesized from an empirical benchmark across 6,436 verified test runs (38,616 Stamina spent) conducted by veteran Chinese theorycrafter 空相面灵气 (Mian-lao) across multiple accounts during the live anniversary launch:

1. Manual / Auto Tower Climb (999 Runs)

  • ◆
    Sample Size: 6,436 runs (Account A: 3,512 runs | Account B: 2,924 runs)
  • ◆
    Total Stamina Consumed: 38,616 AP (6 AP per run)
  • ◆
    6★ Souls Dropped: 1,625 units
  • ◆
    Qingjigui (青吉鬼 / EXP Fodder): 935 units
  • ◆
    Efficiency Metrics:
  • ◆
    23.76 Stamina per 6★ Soul
  • ◆
    41.30 Stamina per Qingjigui EXP Fodder
  • ◆
    *Verdict*: Baseline drop rates are statistically identical to preceding 999 iterations. NetEase has stabilized this rate as the fixed ceiling for anniversary events.

2. Dispatch Delegation (委派)

  • ◆
    Sample Size: 1,702 completed dispatch chests (51,060 AP equivalent)
  • ◆
    6★ Souls Dropped: 2,094 units
  • ◆
    Qingjigui: 1,209 units
  • ◆
    Efficiency Metrics:
  • ◆
    24.38 Stamina per 6★ Soul
  • ◆
    42.23 Stamina per Qingjigui
  • ◆
    *Verdict*: Yield is 1:1 identical to manual climbing. The primary value of free delegation tickets is pure "anti-grind" (*减肝*)—allowing players to expend 12 AP per ticket for a 2x yield in a fraction of the time.

3. Jade Event Tickets (勾玉门票)

  • ◆
    Sample Size: 1,130 tickets tested
  • ◆
    6★ Souls Dropped: 825 units
  • ◆
    Qingjigui: 331 units
  • ◆
    Efficiency Metrics:
  • ◆
    6.848 Jade per targeted 6★ Soul (1,130 / 825 × 5 Jade)
  • ◆
    17.00 Jade per Qingjigui
  • ◆
    *Comparison*: Regular monthly events cost approximately 14–16 Jade per 6★ soul with full random pool dilution. Anniversary tickets provide a >200% drop density boost AND permit custom pool targeting.

Strategic Takeaways for Your Allocation
Jade Event Tickets: Essential Purchase. At ~6.85 Jade per targeted 6★ soul, the drop efficiency is over 2x higher than standard monthly events, plus you choose the specific soul drop pool.
Dispatch Delegation (委派): Stick to free delegation tickets. Purchasing extra dispatch with Jade costs 24 AP + 4 Jade per 6★ soul; conserve your Jade unless you have surplus AP.

Resource Economy & Consumption Axioms

1. The Jade Event Ticket Mandate (必买)

Every player with at least 3,000–5,650 Jade should prioritize capping the daily Jade event tickets in the event shop.

  • ◆
    Each ticket costs 5 Jade.
  • ◆
    In standard monthly events, event scores and shop conversions yield roughly 0.3 of a 6★ box per equivalent exchange. In this anniversary event, ticket drop density is doubled.
  • ◆
    Crucially, tickets pull exclusively from your Custom Soul Selection pool rather than the diluted 70+ general soul pool. Getting targeted souls (such as slot-2 Speed / slot-6 Crit DMG) in an isolated pool carries exponentially higher valuation than random drops.

2. The Delegation / Dispatch Trap (勾玉委派)

A common point of confusion is whether players should spend Jade on additional Dispatch Delegation Tickets.

  • ◆
    The Mechanism: Paid delegation tickets do NOT increase drop rates. They simply increase the maximum stamina you are allowed to burn through dispatch (from 6 AP to 12 AP per ticket).
  • ◆
    The Cost: Calculating the marginal cost reveals you are paying 24 Stamina + 4 Jade for every additional 6★ soul produced through paid dispatch.
  • ◆
    The Verdict: If your total stamina hoard is under 20,000 AP, DO NOT BUY paid delegation tickets. You will exhaust your AP reserves prematurely without gaining extra loot per AP. Only buy them if you are a whale with 50,000+ AP or have limited physical time to leave an emulator running.
Resource Trap Warning
Alleviating "Stamina Anxiety": NetEase has rolled out three 999-level drop events within this calendar year (520 Celebration, Martial Arts Assembly, and 10th Anniversary). Average player stamina pools are naturally depleted. Do not feel compelled to hit 999 if your resources are modest. Completing 300 to 500 runs while maintaining a 10,000 AP baseline for daily routines is a sound, stress-free strategy.

Custom Soul Selection (御魂自选) & The Modern Meta Paradigm

The anniversary allows you to lock 4 Custom Souls into your drop pool. Choosing these 4 slots effectively determines the value of your entire event.

The Three Pillars of Selection

  • ◆
    Acquisition Difficulty: Does the soul come from a weekly-capped, high-AP dungeon (like Six Realms or Sea of Eternity), or does it drop from a standard weekday dungeon?
  • ◆
    Amplifier Multiplier & Versatility: Does the soul provide a universal damage multiplier (like Kyoukotsu or Possessor) that powers multiple PvE speed-teams?
  • ◆
    Account Progression Need: Does your roster actively field Shikigami that require this soul?

The Demise of Fortune Cat (招财猫)

For years, the Onmyoji community followed the maxim *"All things can be Fortune Cat" (万物皆可招财)*. In the modern meta, selecting Fortune Cat in a custom event is an obsolete blunder:

  • ◆
    Zero Scarcity: Fortune Cat drops every Tuesday in Soul 10 / S11 Moan. You can farm it 52 weeks a year with normal stamina. Wasting an annual anniversary custom slot on a Tuesday soul forfeits rare dungeon drops.
  • ◆
    Superseded in Meta: In modern PvP below *Grand Celebrity*, orbs are more reliably provided by Wisp (unconditional -1 orb cost), Dangler (healing + orb bar push). In PvE, teams rely on dedicated orb generators like /shikigami/kannazukiSSR or Azure Basan.
  • ◆
    Conclusion: Save your custom slots for dungeon-locked souls from S12 Judgement (大蛇神·神罚) and S13 Aether Orochi (终焉大蛇·虚无).

4-Week Global Preparation Roadmap Checklist

Since Global is ~4 weeks away from the 10th Anniversary patch, use this operational checklist:

  • ◆
    [ ] Week 1 (AP Stockpiling): Halt arbitrary weekday soul farming. Bank all AP rewards from Guild Feast, Realm Bento, Daily Quests, and maintain AP mails in your mailbox without claiming until needed.
  • ◆
    [ ] Week 2 (Jade Accumulation): Target a minimum reserve of 3,000 to 5,650 Jade. Maximize weekly Secret Zone clears, Area Boss kills, and reach Tier 8+ in weekly Duel for tier payouts.
  • ◆
    [ ] Week 3 (Inventory Sanitation): Release or feed useless 4★ and 5★ souls to your Gluttonous Ghoul (贪吃鬼). Clear out at least 1,500 to 2,000 inventory slots to prevent farming interruptions during auto-runs.
  • ◆
    [ ] Week 4 (Speed-Tuning Calibration): Pre-build your speed-clear team and test damage breakpoints. Ensure your carry has 100% effective Crit rate and that your orb supply runs continuously on Auto.
