Aethermancer, the monster-taming roguelite from Moi Rai Games, has received its first major Early Access update on Steam. Titled Full of Fusion, the update introduces a second player class, two new Champion monsters, unlimited progression, and Epic Artifacts.
The game puts you in control of a party of three monsters as you guide them through Terastae, a world where creatures have defied the virtues of their realm and are trapped in a cycle of death and rebirth. Combat is turn-based and built around the four elements of Aether, with every action carrying weight because death is permanent. Lose a monster in battle and it's gone. You can rebirth their souls, bringing them back changed but carrying the strength of their previous lives, still bound to you through the soul bond you originally formed. The tension between attachment and loss runs through every encounter. Each level up forces a choice about how your monsters grow, drawing from a dynamic skill pool that reacts to your previous decisions and the composition of your current team. No two runs produce the same party, and experimentation with different builds is the point rather than a side effect.
Strategy in combat goes deeper than picking the right attack. You manage Aether to unleash spells, purge enemy Aether to disrupt their plans, grind opponents down with poison, or protect allies behind shields. Different strategies are viable, but the permanent death system means miscalculation has real consequences. Procedurally generated levels keep the terrain shifting between runs, and your monsters gain Worthiness as you push further. When you finally lose your party, you come back stronger and try again.
You are the Aethermancer, someone with the rare ability to form bonds with the mythical creatures of Terastae and guide them through the Fractured Ruins. Various characters appear throughout your journey to help you and your monsters, their stories unfolding through your choices and encounters. A village serves as a hub where you gather townsfolk, hear them out, and do what only an Aethermancer can. The lore builds gradually across runs rather than front-loading exposition.

Full of Fusion's headline addition is the Aether Alchemist, a new player class that lets you experiment with Monster Infusion. Where the base class works within each monster's existing framework, the Alchemist can replace Signature Traits, Types, or Elements entirely, opening up build possibilities the original class can't touch. The update also adds two Champion monsters to discover and tame. Eidos and Eidolon are a support-focused pair that can access consumed buff stacks and bring them back from the afterlife, while Dullahan slots into defensive parties built around shields and tanking. The Worthiness progression system, previously capped at Level V, is now unlimited, and monsters at Level V or higher appear in Pilgrim's Rest. Artifacts used in battle can now roll as Epic Artifacts with upgraded effects.
Aethermancer currently holds a 93% Very Positive rating from over 2,000 reviews on Steam, where it remains in Early Access. Every class, every monster pairing, every skill choice nudges your run in a different direction, and the Alchemist class pushes that variability further by letting you rewrite the rules your monsters play by.
