Sekiro: Shadows Die Twice is packed with concealed mini-bosses, unmarked Sculptor’s Idols, and story-critical secrets that are extremely easy to miss—especially if you’re pursuing specific endings or aiming for a 100% completion run. This guide delivers an SEO-focused, full exploration walkthrough covering every hidden boss encounter, the exact locations of secret Sculptor’s Idols, and all major missable items and events you must secure before progressing.
Preparation for Hidden & Missable Content
- Eavesdrop often: Many secret events unlock only after specific eavesdrops.
- Revisit older areas: New mini-bosses appear after story milestones.
- Carry Divine Confetti & Pacifying Agents: Crucial for apparition fights.
- Check alternate paths: Sekiro hides entire idols behind optional grapple routes.
- Avoid rushing main bosses: Advancing too early can permanently lock quests.
Hidden Bosses & Mini-Bosses — Complete Locations

Projectile terror beams have a delay—circle strafe to avoid them.

Secret Sculptor’s Idols — Exact Locations & How to Unlock
