Preparing for the Eris Battle

• Activate a faith early: Choose any faith at the start of a floor before reaching Apollo’s level. This initiates a faith meter that doesn’t need to be full—just partially filled before facing Apollo.
• Avoid Apollo’s temple: Do not interact with the faith temple on Apollo’s floor. Using it ends your run prematurely.
• Defeat Apollo with faith intact: Ensure your faith meter hasn’t depleted. Victory will unlock a portal to Eris’s domain instead of returning you to the hub.

Optional Mechanics on Eris’s Floor

• Temples here can be used safely—they won’t affect your ability to battle Eris.
• Faith levels may fluctuate without consequences.

Confronting Eris

• Locate her boss room through exploration, similar to earlier battles.
• Winning unlocks progression to Hyperion, the true finale.

Key Questions Answered

• What defines a faith? A system that accumulates power based on selections made each floor.
• Does faith need maxing? No—only activation matters.
• Can I use Eris’s temple? Yes, unlike Apollo’s.
• Consequences of entering Apollo’s temple: Instant run termination.
• Is Eris the last boss? No—Hyperion follows her defeat.
