Combine cards to craft tools and weapons to create different units. Farm your lands with farmers, send an explorer to a cave, a thief to steal a mansion or soldiers to conquer a town. Manage your resources to create the best units to defeat every boss. Cards can be combined in multiple ways depending on the building used. The game has several buildings that allow players to use cards in multiple ways. Castle Land - Farm your lands to extract resources. Use resources to craft weapons and tools. Blacksmith - Craft tools and weapons using items. Discover new cards by experimenting with different items. Academy - Teach peasants a profession using tools. Give a peasant an axe and you’ll get a lumberjack that can extract better resources from the forest. Armory - Train your units with different weapons to create soldiers, archers, mages, necromancers and more. Explorer’s Clan - This terminal allows players to explore locations. Combine a unit card with a location to explore it and see what the unit found. Thieves Den - Use units to steal from locations. Send a thief to a manor, town or castle to see what it gets. Conqueror’s Guild - Conquer locations using units. Each location spawns a combat phase that players must win to get rewards. There are hundreds of cards to discover throughout the game. To make it easier to view every discovered card we built an album that displays the card with its name, description and recipes. We also added card backs to the album, you can select your favorite from a collection of pop culture rubber ducks. Everything in the game runs simultaneously, including combat. This means player units and enemies will attack automatically with random attacks between normal (melee, range or magic) and special abilities (freeze, stealth or heal). Some units also have passive abilities that are active throughout the entire combat. Strategize accordingly depending on the type of enemy you are dealing with to keep your units alive. The game has several bosses to defeat. Each boss comes with a set of challenges that dramatically change how the game works, making runs more interesting for players that have mastered the basic mechanics of the game.
