Mastery XP: Fastest Ways to Reach 600

Understanding Mastery

Mastery levels range from 0 to 600 for all weapons, fighting styles, and Devil Fruits. Higher mastery unlocks more powerful moves and increases damage output.

XP Formula

The XP required per level follows the formula: 54 + ((2 × mastery^2.26 + 30) × 0.5). This means higher levels require exponentially more XP.

Best Grinding Locations

Choose NPCs that match your level and give good XP. Higher-level areas provide more mastery XP per kill. Popular spots include Castle on the Sea, Haunted Castle, and Cake Land.

2x Mastery Gamepass

The 2x Mastery gamepass cuts your grinding time in half. If you're serious about reaching max mastery, this is one of the best investments you can make.

Efficient Strategies

Use auto-clicker setups where allowed, focus on NPCs with low health but good XP, and always grind during 2x Mastery events. Raids also provide excellent mastery XP.
