offbrand games — creators behind Demon Bluff, Ultrapool, Rivals of Aether II — and moi rai games — the studio that brought you Monster Sanctuary — have teamed up to launch Maverick’s Compendium, the massive third free content update for monster-taming roguelike Aethermancer, available right now in Early Access on Steam.
Rewriting the rules of party building, welcoming a crossover hero, and giving players powerful new ways to track their progress — this update isn’t just more content. It’s a fresh invitation to play differently.
What Is Aethermancer? — Catch, Command, Conquer the Fractured Ruins
Launched in September 2025 in Steam Early Access, Aethermancer blends monster collection with roguelike depth — every run takes you into the shifting Fractured Ruins, where you recruit and evolve a party of beasts, forge powerful synergies between them, and face escalating challenges. No two descents are the same, and the team composition you build defines your survival.
Until now, smart players leaned into matching monster types for maximum synergy. Maverick’s Compendium turns that strategy on its head.
Headline Feature — The Aether Maverick: Diversity Is Strength
The biggest addition is the Aether Maverick, the game’s third playable class — and a complete reimagining of how you build your squad.
While other classes reward stacking matching types for combined effects, the Maverick does the opposite: the more diverse your party, the stronger you become.
- 6 distinct Types ? Higher chance of exclusive Maverick Skills appearing on level-up
- 9 distinct Types ? Free monster reactivation every 2 rounds — potentially game-changing in tight fights
- Unique buffs scale directly with variety — oddball, off-meta parties are now the optimal path to victory
“Where the Aether Tamer seeks perfect harmony, the Maverick thrives on glorious chaos. Mix everything, watch it explode — and win.”

Two New Beasts — Community Spirit Meets Rivals Crossover
Kragg — The Rock-Solid Visitor
Making the leap from Rivals of Aether — offbrand’s beloved platform fighter — Kragg brings his earth-shaking power to the Aethermancer roster. Stubborn, sturdy, and capable of dominating the frontline, he’s the first crossover monster to join the fray, bridging two universes in style.
Philosopher’s Stone — Forged by the Fans
Designed from community submissions and feedback, this shimmering addition is the players’ own creation brought to life. Mysterious and versatile, it rounds out the Alchemical Woods biome — and proves that the community’s ideas shape the game just as much as the developers’.
Knowledge Is Power — Siriux Journal & Combat Log
Maverick’s Compendium doesn’t just add things to fight — it gives you the tools to fight smarter:
- Siriux Journal — A living, growing compendium tracking every monster you meet. Stats, hidden abilities, lore — unlock it all as you explore
- Combat Log — Missed a proc? Lost track of cooldowns? Now every strike, buff and effect is recorded in detail, letting you review, refine and perfect your tactics
- Plus a full suite of quality-of-life improvements — smoother navigation, faster load times, and balance passes across all existing classes
Built to Evolve — A Year of Free Updates
This marks the third major free update since launch — and the pattern is clear:
- Alchemist Class — second playable role, with potion-crafting & experimental synergies
- 12+ New Monsters — expanding tactical options across every run
- Deity Boss Battles — legendary encounters that test fully built parties
- Alchemical Woods Biome — entirely new zones, hazards and rewards
- Maverick’s Compendium — and now, diversity-driven gameplay
All free. No DLC paywalls. No premium gates.
“When you buy Aethermancer, you’re not buying a static product — you’re joining a development journey. Every major update stays free, because this game grows with its players, not at their expense.”
