Sin Of Pride

Sin of Pride is a Sea 1 boss encountered exclusively inside the Boss Rush mode, making it fundamentally different from the open-world spawnable encounters found elsewhere on the first sea. Rather than tracking a respawn timer or purchasing a summoning key, players must progress deep into the Boss Rush gauntlet before this encounter becomes available — which means every attempt at its loot requires clearing the preceding stages first.

At 90 million HP, Sin of Pride is a genuine endurance test for Sea 1 standards. Its health pool demands sustained DPS over an extended fight, so bringing your strongest fruit or weapon and keeping your Haki armed throughout is non-negotiable. Because the Boss Rush format doesn't allow retreating and re-entering mid-run, dying to Sin of Pride costs you the entire run's investment, making defensive awareness just as important as raw offensive output.

The drop pool here is narrow but noteworthy. The Sin Of Pride Sword and the Sun Armor Accessory are direct rewards from this fight, giving it exclusive loot you cannot obtain anywhere else on Sea 1. The The One Title sits at a 0.85% drop rate — low enough that you should treat it as a fortunate bonus rather than a farming goal. If you are primarily after the sword or armor, completing Boss Rush consistently is the real grind; the title will eventually follow.
