About This Game

Your oath is written in thorns.

Face the Unbound in deliberate, turn-based combat. Read their intentions, choose your target, and decide when to Attack or Guard. Break their Resolve to leave them Staggered and turn a dangerous encounter into an opening.

Every victory earns Oath Points to spend across a branching web of Sigils. Build your Power, reinforce your defenses, and reach for Keystones that reward your commitment with powerful bonuses.

As you grow, claim your Recompense: learn an Ability, ascend one you already wield, accept a Blessing, or discover a passive Relic. Abilities charge each turn and fire automatically, while Relics reward the way you fight.

Death ends your run, but your bound Sigils remain. Rise again, confront each Trial’s Warden, and earn Covenant Points. When you are ready, weave a New Fate: surrender your current progression, reroll the entire tree, and begin again with permanent strength.

  • Read the enemy. Plan around incoming attacks and exploit Staggered foes.

  • Shape your build. Explore a sprawling Sigil tree with powerful Keystones and purchasable Relic slots.

  • Combine your rewards. Equip up to six Abilities and discover Relics that work with your strategy.

  • Grow beyond defeat. Keep your Sigils through death and gain permanent bonuses by weaving New Fates.
