Challenges are short, focused missions that often have specific objectives or character restrictions. They are excellent for earning experience, rupees, and rare materials. You can find challenges scattered across the world map, often appearing after completing main story missions or other challenges. Some challenges unlock new characters or powerful weapons.
Always check the recommended level and rewards before attempting a challenge. Many challenges have unique conditions, such as 'defeat all enemies within a time limit' or 'only use Sheikah Slate Runes.' Mastering these challenges will hone your combat skills and provide a steady stream of resources for character development. Prioritize challenges that offer new character unlocks or significant weapon upgrades.
