Catamyst is an action roguelike that requires players to craft potions and defeat waves of molecular amalgamations. You'll be combining real-world chemistry with magical potions to destroy the monstrosities that have emerged.
Willow is a Cat Witch who lives comfortably in the woods as its guardian.
Recently, Amalgamations made of Chemical Elements and magical Vis have been spawning in nature and disrupting the ecosystem. The problem has been tracked back to a single source: A highly magical Obelisk that has emerged in the forest clearing.
Willow must use their prowess as a forest guardian to brew potions, collect molecules and imbue Vis into powerful enchantments to fight back these monstrosities.
Willow has access to a vast amount of potions at their disposal. Potions are thrown at groups of enemies and each potion has a unique characteristic.
Potions are crafted using Molecules collected from defeated amalgamations. These potion recipes are based on real-world chemical processes/compounds, with affects to match!
Potions level up as you defeat enemies, allowing you to harness unique builds and strategise the optimal ways to overcome the trials.
Master 25+ unique potions with recipes made from 7 different Molecule types.
Destroying the Obelisk means siphoning all of its magical Vis. The Obelisk can fight back and will create increasingly stronger amalgamations to stop Willow in their tracks. However, Willow can use this siphoned Vis to their advantage - by creating powerful Enchantments.
Enchantments are upgrades to Willow that can make them significantly more powerful. Enchantments can be attuned reguarly, whilst also spending Vis collected throughout the waves. Powerful Enchantments can drastically change how the game is played.
Catamyst offers 75+ unique enchantments, across 4 rarities, to add a vast amount of variety across runs.
Catalysts are powerful augments that you can attach to your potion, granting it new abilities and power.
Both Catalysts and Potions can each have unique effects that work in synergy with one another. It's important to strategise which Potion/Catalyst combinations are best!
There are 25+ different Catalysts that you can encounter. This means over 500+ unique combinations.
