Limitless Sorcerer

The Limitless Sorcerer occupies Shibuya Station in the First Sea, respawning on a strict five-minute timer with a modest 4 million HP. That low health pool is the point — this boss is deliberately approachable, designed as a high-frequency target that even mid-game players can dispatch quickly and return to in minutes. The real value here is not raw power but repetition: because he spawns so reliably and dies so fast, the Limitless Sorcerer is one of the most efficient bosses to chain-farm in Sea 1.

What makes him especially attractive is the breadth of his drop table. At the top: Haki Color Reroll at 50% and Race Reroll at 35% — solid odds on two different customization currencies per run. The Limitless Key at 30% unlocks access to a specific area or challenge, making it doubly useful to acquire alongside standard rerolls. Trait Reroll sits at 27.5%, Boss Ticket at 25%, and Void Fragment at 20%, with Dungeon Key following at 15%. For collectors, the Limitless Ring at 8%, the Sorcerer Blindfold accessory and Honored One Title both at 5%, and the Infinity Core at 3% round out the table.

With a five-minute window between kills, the best approach is to tag the boss the moment it spawns. The combination of Haki Color Reroll, Race Reroll, and Trait Reroll all dropping at meaningful rates makes each run genuinely rewarding even when you miss the rares.
