1. Year-End Update: The Catalyst of Evolution (Dec 24, 2025)
The "Forbidden Catalyst" concludes with a high-impact character drop and critical QoL fixes.
New Contents:
- New Meta Entry: Sereniel (5★ Instinct/Hunter) A high-tenacity DPS specialist. Her unique mechanic allows her to recycle "Homing Laser" cards upon breaking enemies [07:41].
- Tiertactix Recommendation: Pair with the Judgement Flames set for maximum breakthrough efficiency. Note: She is a seasonal limited unit.
- New Partner: Peko Optimized for Ravaged target focus, providing a direct ATK and DMG multiplier against debuffed foes [09:22].
- Spectral Cube Exchange: Surplus pulls after Max Ego convert to currency for Memory Codes, removing the RNG barrier for standard agent growth [15:15].
- Chaos Core Expansion: Boss Hakuga joins; Servant is demoted to Elite, making Elite-tier gear farming more accessible [11:35].
- Codex Improvements (Season 2): Introducing Unique Options to Codex as bonus to make chaos run enjoyable [45:23].
- Unique Codex: New level with surprise reward and side-storyline [47.35].
Change & Improvements:
- 2x Speed Mode: Finally implemented for Unidentified Areas to cut down on daily grind time [13:32].
- Memory Fragments UI/UX Rework: Improve convenience in upgrading and equipping and clarity of the number of times an option has been upgraded [52:48].
- Skippable Story: Parts or certain scenes in the story are made skippable [54:22].
Rewards & Gifts:
2. Season 2: Planet Verne Strategy (February 2026)
The tactical environment shifts to the volcanic hazards of Planet Verne and the ruins of Critias.
New Contents:
- Spiral Tower of Screams: A permanent 150-floor endgame mode. Unlike current speed-clear metas, this tower prioritizes Survival and EHP (Jan 14) [35:32].
- Galactic Martial Arts Tournament: A seasonal event where you can temporarily incorporate "Monster Cards" into your deck [31:01].
- First Sync System: This is a game-changer for F2P players. It allows you to test-drive unbuilt agents immediately without spending resources [38:28].
- Season Board: Seasonal progression/ achievement in a glance. Obtain Galactic Medals (stickers) to decorate save data [34:22].
- New Monsters/ Encounters: Automaton, Colossus. Enemies with destructible parts. [32:06].
- Guild Office: Complete missions and receive rewards [41:56].
Change & Improvements:
3. Season 3: The Corruption Era (April 2026)
The highest tier of power-scaling arrives with the Corruption system.
New Contents:
- Corruption Mode: A new growth path where agents gain Corrupted Skills and unique visuals (e.g., Orlea’s alternate form) [01:04:16].
- Chaos Raid (Assault): The "Pure Roguelike." Save Data is disabled here, but the Graveyard is removed, allowing you to play the same powerful cards infinitely in a single turn if you have the energy [57:27].
- Purification Protocol: A multi-deck mode requiring three separate teams to tackle infected systems [01:00:09].
Change & Improvements:
4. Rebalancing & Reworks
Upcoming changes mentioned but not listed on 2026 Roadmap:
Tiertactix Action Plan: Prepare Now
Do these now!
- Anchor Discipline: Sereniel is a Seasonal Limited Hunter, save every Anchor for Dec 24.
- Team Management: Tressa or Cassius rework will have a refund system for players unhappy with the change. Plan a Third Team if they are in your 2-Team roster. This act also prepares you for Purification Protocol in the upcoming Season 3 (April).
- Gear Management: Do not dismantle "almost-perfect" gear. Keep pieces that are one substat away from being "God-tier"—the Editing Tickets in April will fix them.
- Community Networking: Aggressively friend-request high-performing players now. Accessing a desired Save Data via the Borrow System will be the fastest way to farm Simulation Dungeons in Season 2, and experience other builds.
