How to fight Satan
The Sheol finale begins with The Fallen, then moves through Satan's projectile and stomping forms.
Before entering
Keep resources for three distinct stages. The Negative route continues to the Dark Room after Satan.
- 1
The Fallen
Watch for: The Fallen enters with two Kamikaze Leeches before Satan becomes the main target.
Try: Clear the opening stage while watching for leeches near your movement path.
- 2
Upper-room Satan
Watch for: Satan fires spreads and can use hand or mouth Brimstone beams based on Isaac's position.
Try: Read the wind-up and move out of a beam's line before returning fire.
- 3
Foot stomps
Watch for: The final stage repeatedly drops two feet near Isaac's previous positions as leeches appear.
Try: Keep moving between stomps and leave a clear route away from the next landing spot.
