Sanctum Ruins

Sanctum Ruins is a strategic roguelike deck-builder in which you descend into a living dungeon, build a deck and fight increasingly dangerous foes. Each run differs, asking you to adapt your strategy, find powerful cards and push deeper into the Sanctum.

Build your deck

You add cards as you progress, choosing how to combine their abilities into powerful synergies. Each card choice shapes your strategy.

Choose a class

The game has eight classes, each with a distinct playstyle. You can play as two classes from the start and unlock the others by playing:

• Cleric: use healing, devotion and righteous damage.
• Dungeon Knight: fortify, block and counterattack.
• Diabolist: draw on dark contracts and demonic power.
• Oathsworn: take sacred vows for powerful rewards.
• Fey-Touched: rely on chaotic luck and whimsy.
• Celestial: wield divine radiance and holy magic.
• Summoner: command minions in battle.
• Bargainer: make deals with powerful entities.

Descend through the Sanctum

A run spans three challenging acts, each with unique enemies, elites and bosses. You choose your route through events, shops and rest sites, each offering strategic decisions. Permanent upgrades carry over between runs, helping you grow stronger even when a run ends in defeat.

Dark, ancient powers stir in the depths of the dungeon as you make your way toward its heart.
