The Doombringer Bloodline in Sailor Piece is a Legendary rarity bloodline introduced in a recent update, providing players with significant advantages in gameplay. To acquire this bloodline, players must collect Bloodline Stones, which can be obtained by defeating enemies on Sea 2 islands, through redemption codes, chests, and from Sea Beasts in the Open Sea. Notably, it takes 750 Bloodline Stones to guarantee a roll for the Doombringer due to the pity system. The Doombringer Bloodline enhances a player's stats with 40% Max HP, 32% Damage, and a 12% Luck Multiplier, among other benefits. Its passive ability allows a 20% chance to deal 20% more damage for eight seconds when using a skill. Although it shares similar buffs with the Demonic Bloodline, it is slightly less effective, making it a temporary option until players can obtain stronger bloodlines like Demonic or Empyrean.
