How does the battle system work?+
Battles are auto-played in real-time. Your squad of up to 4 heroes fights enemies using basic attacks and abilities. Heroes have mana pools that regenerate over time, and you can manually target enemies or trigger abilities. Synergies between hero classes provide bonus effects.
What are biomes?+
The world map has 30 biome stages, each with unique enemies, themes, and difficulty levels. Biomes range from forests and caves to astral planes and void citadels. Clear all enemies in a biome to unlock the next one. Boss fights appear every few stages.
How does the building system work?+
Your city has 11 buildings: Tavern, Market, Lumber Mill, Quarry, Farm, Barracks, Blacksmith, Alchemist, Gem Mine, Guild Hall, and Summoning Gate. Each building produces resources or provides bonuses. Upgrade them using wood and stone to increase output.
What is the dungeon crawling mode?+
Dungeon crawling is a first-person 3D exploration mode with procedurally generated floors. Navigate rooms, encounter enemies, find treasure, and face boss rooms. An AI Dungeon Master (powered by Claude) narrates your adventure with unique story elements.
How do hero classes and synergies work?+
Heroes come in classes like Fighter, Ranger, Cleric, Sorcerer, Rogue, and more. Pairing specific classes together unlocks synergies — for example, Holy Shield (Cleric + Paladin) grants a defensive bonus, while Arcane Surge (Wizard + Sorcerer) boosts magic damage.
What are idle earnings?+
Kosmic Dungeon is an idle RPG — your heroes keep earning gold, resources, and XP even when you're offline. When you return, you collect accumulated rewards. Building upgrades and VIP level increase your idle earning rates.
