Apocalyptic Shadow: Instigation of the Locusts (November 11)
The update cycle kicks off with Apocalyptic Shadow refreshing first on November 11, 2025, at 4:00 PM server time. This iteration, titled “Instigation of the Locusts,” presents a unique challenge format that tests your single-target damage capabilities and sustain.
Boss Lineup Analysis:
- First Half: Sky-Shrouding Stardevourer Swarm demands consistent AoE damage and strong shields to counter its swarming mechanics
- Second Half: Phantylia returns with her devastating multi-target attacks and illusion-based mechanics requiring precise timing and cleansing abilities
As usual with Apocalyptic Shadow, every node across all four stages features identical bosses, allowing you to perfect your strategy across multiple attempts. Each stage will include unique buffs tailored to specific character archetypes, so analyze these carefully before committing your teams.
Strategic Considerations: The Sky-Shrouding Stardevourer Swarm requires characters with strong AoE capabilities like Herta, Jade, or Himeko. For Phantylia, Preservation or Abundance characters become essential—consider building teams around Aventurine, Lingsha, or Fu Xuan to survive her relentless assault.
Since Apocalyptic Shadow rewards favor quality over quantity (you only need to clear content once per cycle), focus on perfecting one strong team composition rather than splitting resources across multiple mediocre teams.
Pure Fiction: Multi-Wave Chaos (November 24)
Pure Fiction refreshes on November 24, 2025, at 4:00 PM server time—thirteen days after Apocalyptic Shadow. This game mode emphasizes speed, efficiency, and multi-target damage, requiring players to eliminate waves of enemies within strict turn limits.
Boss Lineup Breakdown:
- Stage 3: Senior Staff Team Leader and Noontide Gryphon present a dual-boss challenge requiring balanced damage output
- Stage 4: Cocolia returns alongside First Genius, Entelechy, Zandar—a combination demanding both single-target burst and sustained AoE pressure
Pure Fiction allows players to build two full teams of four characters each, providing flexibility in tackling different stages. The mode rewards aggressive gameplay—characters with follow-up attacks, DoT capabilities, or multi-hit abilities excel here.
Team Building Tips: Consider characters like Dr. Ratio, Topaz, Clara, or Kafka who generate consistent damage through follow-up attacks or damage-over-time effects. The Cocolia encounter particularly favors Ice-resistant teams or characters capable of cleansing debuffs quickly.
Since Pure Fiction refreshes mid-update, it provides an excellent opportunity to test newly acquired characters or experiment with unconventional team compositions without the pressure of permanent progression systems.
Memory of Chaos: Monkey Business (December 8)
Memory of Chaos receives its refresh latest in the cycle on December 8, 2025, at 4:00 PM server time—right before version 3.7 concludes. This timing allows players to leverage newly built characters and refined strategies developed throughout the update period.
Stage 11: Defensive Challengers The first half features Gepard alongside First Genius, Entelechy, Zandar. Gepard’s shield mechanics combined with First Genius’s support capabilities create a defensive wall requiring sustained damage and shield-breaking potential.
Stage 12: Offensive Powerhouses
- Node 1: Stellaron Hunter Sam brings aggressive fire-based damage requiring proper elemental coverage
- Node 2: Borisin Warhead Hoolay concludes the challenge with devastating physical attacks and counter mechanics
Quick Clear Feature: Memory of Chaos includes the “Quick Clear” functionality, allowing players who’ve already achieved maximum stars in previous cycles to instantly claim rewards without re-clearing stages. This quality-of-life feature saves significant time for veteran players while maintaining challenge accessibility for newer Trailblazers.
Optimal Strategy: The Sam encounter favors Wind, Ice, or Imaginary damage dealers who can exploit elemental weaknesses. For Hoolay, characters with high toughness damage and crowd control abilities become essential—consider Blade, Yunli, or Physical Trailblazer for this matchup.
Stellar Jade Rewards: Maximizing Your Earnings
Each endgame activity offers substantial Stellar Jade rewards, making them essential for free-to-play and low-spending players:
- Apocalyptic Shadow: Up to 480 Stellar Jade for full clear
- Pure Fiction: Up to 600 Stellar Jade for maximum stars
- Memory of Chaos: Up to 1,600 Stellar Jade across both stages
Combined, version 3.7’s endgame activities provide 2,680 Stellar Jade—enough for approximately 16 pulls toward limited character banners. Over an entire update cycle, diligent players can accumulate enough premium currency for guaranteed five-star acquisitions through the pity system.
Preparation Strategies for Success
Team Diversity: Build at least two well-rounded teams covering different elements and damage types to handle varied boss mechanics
Character Investment: Prioritize leveling characters to 80, maxing crucial traces, and equipping appropriate Relics with proper main stats
Light Cone Optimization: Even four-star Light Cones at high superimposition levels can match five-star options—don’t overlook accessible alternatives
Pre-Planning: Review boss mechanics through community resources before attempting challenges to understand attack patterns and vulnerability windows
Resource Management: Save Trailblaze Power for targeted Relic farming between endgame refreshes, focusing on sets that benefit multiple characters

Frequently Asked Questions
Q: Can I complete all three endgame activities (Apocalyptic Shadow, Pure Fiction, Memory of Chaos) with the same team compositions, or do I need different characters for each?
A: While technically possible to use similar teams across activities, it’s highly inefficient and often unsuccessful due to fundamentally different mechanics. Apocalyptic Shadow emphasizes single-target sustained damage and survival against powerful bosses, favoring Preservation/Abundance characters with strong DPS. Pure Fiction rewards multi-target AoE damage and turn efficiency, making follow-up attack characters and DoT specialists optimal. Memory of Chaos demands balanced teams handling both AoE waves and single-target bosses with elemental diversity. Most players maintain 2-3 distinct team archetypes: a boss-killing single-target team (Hunt/Destruction focus), an AoE clearing team (Erudition focus), and a balanced hybrid team. Character overlap is common—units like Aventurine, Ruan Mei, or Robin work across multiple modes—but expecting one team to excel everywhere will limit your reward potential significantly.
Q: What happens if I miss the refresh dates for these endgame activities? Do I lose the rewards permanently?
A: Missing refresh dates doesn’t permanently lock you out of rewards, but it does reduce your earning window. Each endgame activity remains available for its entire cycle duration—approximately two weeks—before the next refresh. For example, if Apocalyptic Shadow refreshes November 11 and you don’t attempt it until November 20, you still have several days to complete it before Pure Fiction’s November 24 refresh. However, Memory of Chaos refreshing December 8 (near update end) provides the shortest window since version 3.8 launches shortly after. The critical limitation is that you cannot claim rewards from previous cycles once a refresh occurs—if you didn’t clear Apocalyptic Shadow before its refresh, those rewards are lost. The “Quick Clear” feature in Memory of Chaos helps by instantly granting rewards if you previously achieved maximum stars, but this only applies to content you’ve already mastered. For optimal Stellar Jade accumulation, attempt each activity within 2-3 days of refresh to allow multiple attempts if needed.
