For the ultimate challenge, Sekiro offers two optional difficulty modifiers:
- Charmless: At the start of New Game+, you can choose to give Kuro's Charm back to him. This means you take chip damage even on perfect deflections, forcing absolute precision.
- Demon Bell: Found in Senpou Temple, ringing this bell increases enemy difficulty, health, and posture, but also boosts item drop rates and Sen/XP gain. It can be toggled off at any time.
