Onmyoji Uber Boss Event Guide

Master the Onmyoji Uber Boss event with our complete guide covering stage discovery, daily 150% stat boosts, 100-boss milestones, and shop reward priorities.

Clearing the recurring Uber Boss event—often known in community discussions as Super Ghost King—requires triggering boss stages through daily farming zones, optimizing lineups around rotating rarity stat buffs, and completing 100 self-discovered boss clears to secure the exclusive Orochi God Frame. Points and Feats earned from defeating bosses fund shop acquisitions such as a random SSR Shikigami and Grade 6 Souls, while competitive scores rely on logging your highest single-run damage in the daily Vanquish window between 2:00 and 24:00 EST.

Triggering Encounters: Farming Stages and the Search Tool

Boss encounters do not simply appear on a static campaign map. Players generate boss spawns during the Defense phase by spending AP stamina across three standard grinding hubs or by activating an internal detection mechanic:

  • Exploration Zones: Standard chapter exploration runs can trigger an encounter upon boss victory.
  • Evolution Zones: Material grinding stages for awakening Shikigami double as encounter triggers.
  • Soul Zones: Regular Soul farming runs serve as productive trigger stages while accumulating upgrade materials.
  • Uber Boss Search Function: A dedicated in-game search mechanic located inside the event interface triggers encounters directly without requiring zone clears.

Challenging dozens of bosses daily strains standard AP stamina. Players must budget stored AP packs or buy refills through Onmyoji S-Jades to sustain the farming volume required for summon scrolls and Grade 6 Souls.

Daily Powerful Shikigami: Stat Boosts and Rarity Buffs

Daily lineups hinge on the rotating roster of Powerful Shikigami. Designated units gain substantial offensive and defensive multipliers based strictly on base rarity, as detailed in the official event documentation:

  • SP and SSR Shikigami: Receive a 150% increase to ATK and DEF.
  • SR Shikigami: Receive a 125% increase to ATK and DEF.
  • R Shikigami: Receive a 100% increase to ATK and DEF.

A 150% stat bonus reshapes overall damage output, making daily adjustments essential. When an AoE attacker holds the SP/SSR bonus, run them as the lead carry to clear minion waves quickly. On days when single-target specialists carry the buff, pivot them into your primary boss-assault squads to burn down high-health commanders.

Rarity TierATK & DEF IncreaseStrategic Role in Lineups
SP / SSR150% boostPrimary damage carry; anchors wave-clearing or single-target burst
SR125% boostSecondary DPS or hybrid offensive support
R100% boostSpecialized utility, damage amplification, or orber support

Managing Fatigue and Friend Point Caps

Consecutive battles generate fatigue, scaling the cost of attacking bosses. Pacing your challenges prevents rapid stamina depletion. If your team cannot finish an encounter in a single session, public sharing allows friends and guildmates to assist, but scoring rules require careful coordination.

In updated Super Ghost King event rules documented by community player analyses, shared point collection is strictly limited: participants can collect friend-assistance points from only their top 20 contributing friends. Relying on an expansive list of low-activity helpers will not yield meaningful progress. Coordinate with an active guild or a dedicated group of 20 strong partners to maximize your shared score pool.

Uber Boss Vanquish: Rules and Ranking Windows

Alongside standard defense boss spawns, the event features the competitive Vanquish challenge. This mode tests peak single-target and burst execution under strict operating conditions:

  • Operating Hours: The Vanquish event opens daily from 2:00 to 24:00 EST according to official game announcements.
  • Score Calculation: Only your single highest damage run of the day is recorded on the leaderboard.
  • Placement Rewards: Final ranking brackets hand out daily distribution rewards based on recorded peak scores.

Sub-optimal and failed attempts carry no ranking penalty because leaderboards track only your single highest score. Use the active window to test turn orders, soul configurations, and stat amplifiers until you log a peak run.

Event Shop Priority and Score Milestones

Defeating bosses rewards two distinct resources: event points for milestone tracking and Feats used as exchange currency in the event shop.

  1. Random SSR Shikigami: The primary high-value redemption in the Feat shop. Prioritize this item before spending currency on repeatable consumables.
  2. Grade 6 Souls and Summon Scrolls: Essential progression items that yield immediate account value.
  3. Orochi God Frame Milestone: Players who discover and defeat an Uber Boss 100 times unlock the exclusive Orochi God Frame (Onmyoji Official News). This milestone requires tracking your personal discoveries rather than relying exclusively on shared friend boards.

Operational Calendar Limitations

Event schedules align with server-specific maintenance windows. Core mechanics, rarity stat tiers, and the 100-clear frame requirement remain consistent across iterations, but active dates and maintenance downtime should be confirmed via in-game notices before spending saved AP.
