Conquer the SummonArk Maze with the power of your deck! Unravel your own strategy in a dungeon full of the unknown! Take on the role of Ceria, a Cardmaster who wields legendary cards with ease. Every dive into the dungeon presents a brand-new challenge with ever-changing layouts and encounters. Defeat monsters using your deck of powerful cards as you push deeper into the labyrinth. Gather new cards and unique relics during your journey and build your perfect deck on the fly. The dungeon consists of three levels, each guarded by a powerful boss—overcome them and claim your treasure! At your base, you can customize your loadout. Adjust your starting deck and available card pool to create new builds and strategies with every run. Experiment freely—no two adventures will ever be the same. Each expedition takes around 30 minutes to an hour, delivering rich, tactical battles even in short play sessions. Strategize, adapt, and discover something new with every playthrough. Throughout your journey, you'll boost your stats—like Strength, Defense, and Action Points (AP)—unlocking multiple playstyles: go all-in with Str, create a tanky fortress build, or outpace enemies with a flurry of agile moves. Even among offensive builds, cards react differently depending on whether you focus on Strength or Magic, giving you plenty of room to explore! The game also features adjustable difficulty settings, including a beginner-friendly mode and a hardcore challenge mode for seasoned players. Review your card collection and past adventures at your base to prepare for your next run. Endless adventures await through cards and strategy. With your ultimate deck in hand, it's time to challenge the depths of the SummoArk Maze! Status System Most card effects scale with your character’s stats. During your adventure, raising the stats that match your deck’s strategy will let you use your cards more efficiently. Life  – Reaching 0 means game over. Str / Mag  – Increases the damage of attack cards. Def  – Reduces incoming damage by half of its value. Blo  – Effectiveness of block cards. Spd  – Affects your AP.
