Examiner Cepheus is the final boss of the Ziggurat, and is the only surefire encounter in the run. He is always on floor 5, Augur Fortress, and is not part of a boss 'pool' (like the other four floors). Cepheus has the highest health of any monster in the game.
Cepheus can attack using any of the following;
- Creating shockwaves on the ground, which do moderate damage and come out twice as fast as the player's jump time,
- Create 5 homing projectiles which must be destroyed by the player or cause high damage, and
- Summoning Demons, Hollow Armors and other strong monsters.
