Memory of Chaos & Pure Fiction Guide

Star Rail endgame modes explained — MoC floors, Pure Fiction scoring, team requirements, and Stellar Jade rewards.

Once your main team is built, endgame modes are the primary challenge and Jade source. Memory of Chaos and Pure Fiction reset periodically and reward strong team building.

Memory of Chaos (MoC) unlocks at Trailblaze Level 50 after completing Simulated Universe World 3. It features 12 floors split into 4 stages, requiring 2 teams of 4 characters each (8 unique characters total per stage).

Requires 8 built characters — plan your roster early
Each stage has 3 floors with escalating enemy levels
Enemies have specific elemental weaknesses — bring counters
MoC resets every ~42 days with new enemy configurations

MoC Strategy

The goal is 36 stars (3 stars per floor × 12 floors). Each floor awards stars based on turn count — fewer turns means more stars. Speed tuning and weakness breaking are essential.

Break enemy weaknesses for bonus turns (action advance)
Bring a dedicated weakness breaker if your DPS doesn't cover all elements
Split your strongest characters across both teams evenly
Use support characters that buff the whole team (Harmony, Preservation)

Pure Fiction

Pure Fiction is a separate endgame mode focused on multi-target AoE damage. Enemies spawn in waves and you score points based on damage dealt. Erudition and AoE DPS characters excel here.

Unlocks alongside or shortly after MoC (Trailblaze Level 50+)
Resets on its own schedule — separate from MoC
Erudition characters like Herta, Serval, and Jing Yuan dominate
Harmony buffers that grant AoE bonuses are extremely valuable

Rewards

Both modes grant Stellar Jade on first clear of each floor/stage and periodic reset rewards. First-time clears are the biggest Jade source — push as far as possible even if you can't 3-star everything.

First clear per floor: Stellar Jade + materials
Reset rewards based on stars earned (aim for 36 stars in MoC)
Pure Fiction rewards scale with points threshold tiers
Apocalyptic Shadow (AS) is a third endgame mode — unlocks later

When to Start Endgame

Don't rush endgame before your teams are ready. Aim for level 70+ characters with level 6+ talents and basic relic sets before attempting MoC floor 8+.

Start MoC attempts at TL 50 even if you can't 3-star — first clears matter
Build 8 characters to at least level 70 with level 80 Light Cones
