A Host worth building

Every fallen enemy.
A new possibility.

Your next breakthrough starts between battles: with a different hero, a stronger bond, or a sacrifice at the Forge.

01

Raise the fallen

Recruit from the creatures you defeat. Hunt the heroes your formation needs, then give them a place in your Host.

02

Forge a purpose

Combine heroes into stronger forms. Build around affinities, roles, relics, and the Signs your heroes have learned.

03

Push deeper

Prepare for the next floor, practice against weekly bosses, and return from Ascension with lasting progress.

Build choices that stay with you

A deeper kind
of mastery.

Keep the Signs you learn. Switch patterns freely, move a Deep Sign to an eligible bearer, and make a new plan for the next encounter.

Weekly bosses reward preparation. Free practice lets you test your Host before committing an attempt.
