Step 02

The guardians

Sentinels, guards, crawlers and remnants defend the halls. Every one of them telegraphs its attacks; learn the signs and the fights become fair.

Step 03

The Colossus

Fill the Boss Soul Catcher to wake the Astral Colossus. Its armour is the real obstacle; find out how to break it, and keep a Seal Fragment ready.

Good to know

  • Rushing into a room before the guardians have shown their attacks.
