Dragon Slayer

Dragon Slayer is a seasonal event boss stationed on Christmas Island in the First Sea, respawning every 5 minutes with a solid 12.5 million HP. As an event enemy it only appears during its designated window, which makes each active period a concentrated opportunity that regular players should not overlook — the drop table is one of the most generous in the game for reroll farming.

The high-percentage drops immediately justify the run: Haki Color Rerolls fall at an extraordinary 75%, making Dragon Slayer the single best source for cosmetic Haki customization in the First Sea. Race Rerolls at 45% and Trait Rerolls at 35% stack on top, so virtually every kill feeds character-building progress in at least one dimension. Boss Tickets at 30% and Wyrm Brand at 25% add consistent utility on every run.

The rarer rewards are what distinguish this event boss from routine stops. Black Frost at 9% is a sought-after item, while Silver Requiem at 3.5% is more elusive and prized. The Ragna Sigil Accessory sits at 2% and the Dragon Slayer Title at 1.5%, both exclusive markers of participation during the event.

Given the 5-minute respawn and generous drop rates, the optimal approach is to form a full lobby, eliminate the boss as fast as possible, and immediately reset — the loot-per-hour ceiling here is among the highest available while the event runs.
