Cosmic Being

Cosmic Being is Sailor Piece's landmark world boss in Sea 2, appearing at Punch Island every 15 minutes without requiring a key or summon item. Inspired by Cosmic Garou from One-Punch Man — notably the first One-Punch Man character introduced to the game — this boss carries cultural weight alongside its mechanical challenge. At 499 billion HP, it is one of the most durable world spawns in the entire game, built for mass participation rather than solo attempts.

The drop table reflects the world-boss design philosophy: broad loot that justifies the communal grind. Cosmic Essence falls at 43.12%, essentially a near-guaranteed material on each kill that fuels Sea 2 crafting. Star Mark at 22.37% and Galaxy Shard at 12.94% add further crafting depth. The Cosmic Body Accessory is an unusually generous 8% for a cosmetic, making it realistically obtainable within a modest farming session. Monster Pulse sits at 5.12%, and the Cosmic Being Title — the flex reward — rounds out the table at 1.75%.

Because Cosmic Being is a world boss, show up early before spawn and coordinate damage with other players. The 15-minute respawn cycle means you can reliably farm multiple times per hour if you stay at Punch Island. High raw-damage builds pay off the most here given the enormous HP pool.
