If you own the 'Expansion Pass' DLC, you can unlock Master Mode. This significantly increases the game's difficulty:
- Enemy Tiers: All enemies are one tier higher (e.g., Red Bokoblins become Blue, Blue become Black).
- Enemy Health Regeneration: Enemies slowly regenerate health if not continuously attacked.
- Floating Platforms: New floating platforms with powerful enemies and treasure chests appear in the sky.
- Limited Saves: Only one auto-save slot, and manual saves are separate from Normal Mode.
Master Mode offers a fresh challenge for experienced players and is a true test of your skills.
