King Legacy

King Legacy is a One Piece-inspired action RPG on Roblox developed by Sea King Games (formerly Venture Lagoons), where players eat Devil Fruits, master fighting styles, unlock Haki, and explore a world spanning three dangerous seas. Released in December 2019 under the name King Piece, it is one of the longest-running anime RPGs on the platform with nearly 4 billion visits and concurrent player peaks exceeding 100,000.

The world divides into three seas, each escalating the challenge of the journey from beginner islands through to endgame raids. Update 10 in March 2026 raised the level cap to 5,450, added the Serpent and Pteranodon raids, overhauled the fishing system, launched Legacy Pass Season 2, and made high-tier items tradeable for the first time:

• 🗺️ Three Seas - progress from 21+ First Sea islands through Second Sea boss encounters to the Third Sea endgame with Kaido and the newest Update 10 content
• ⚔️ 44 Devil Fruits - six rarity tiers from Common to Mythical; fruits spawn on the map every 1-2 hours and despawn after 15 minutes
• ⚔️ Haki Progression - Armament Haki for increased melee damage and hitting Logia users; Observation Haki for dodging; more critical after Update 10 removed bypass mechanics
• 💎 Fighting Styles - 10+ purchasable combat specs including Dark Leg, Dragon Claw, Cyborg, and Water Style, each with V2 upgrade variants
• 🏆 Raids and Bosses - Serpent Raid triggered by fishing in whirlpools, Pteranodon Raid, Kaido for gem farming, and the Sea King that spawns hourly on Legacy Island
• 💰 Trading Economy - exchange high-tier fruits and newly tradeable items including Dragon Fangs and the Dominion Cloak with other players

Stat points distribute across Health, Stamina, Melee, Defense, Sword, and Devil Fruit. Beli is the primary currency from quests and enemies, spent on swords, fruits, and fighting styles. Gems are the premium currency earned from milestones, daily logins, and boss drops. The Legacy Pass battle pass adds seasonal reward layers on top of the core leveling grind.

King Legacy shares its One Piece foundation with Blox Fruits and A One Piece Game but stands out through deeper naval exploration across three full seas and One Piece-faithful mechanics.
