After completing the game, the Boss Rush Mode becomes available. This challenging mode pits Soma against all the game's bosses in quick succession, with limited healing opportunities. It's a true test of your combat skills and soul mastery.

Tips for Boss Rush:
- Optimal Build: Equip your strongest weapon, armor, and a versatile set of souls. The Chaos Ring (if you have it) makes this mode significantly easier.
- Healing Items: Stock up on high-tier healing items like High Potions and Super Potions.
- Soul Strategy: Have a good mix of offensive Bullet Souls (e.g., Minotaur, Mandragora, Killer Clown) and defensive/utility Guardian Souls (e.g., Flame Demon, Succubus, Bat).
- Learn Patterns: If you struggle with a specific boss, replay the main game to practice its patterns.
Successfully completing Boss Rush Mode rewards you with powerful items and unlocks, making it a worthwhile challenge for dedicated players.
