Sea Piece

Sea Piece is a One Piece-inspired action RPG on Roblox where players sail between islands, level up through combat, obtain Devil Fruits, and unlock a full suite of Haki abilities. Developed by Mvngo DEV and launched in May 2022, it accumulated over 20.6M visits and a 92% approval rating during its active development period. The game sits in the One Piece Roblox genre alongside Blox Fruits and King Legacy, offering a more compact experience with a level cap of 1,500.

Players progress by defeating NPCs across escalating islands, earning Beli and experience to reach the next zone. Devil Fruits are the most coveted progression items - they spawn on the map every hour and despawn after 30 minutes if uncollected, or players can buy them from the Fruit Dealer NPC or roll the Fruit Gacha for a random selection. The Second Sea sub-place unlocks for high-level players seeking stronger enemies and better rewards:

• ⚔️ Buso Haki (H key) - Armament Haki that boosts damage output
• ⚔️ Ken Haki (J key) - Observation Haki that improves evasion
• 💎 Conquerors Haki (K key) - Passive damage multiplier requiring both other Haki unlocked first
• 🗺️ Movement Abilities - Geppo (air-stepping via double Space), Dash (Q), and Sprint (Ctrl) add depth to both combat and travel
• 🎭 Races - Character types providing passive stat bonuses, rerollable with Race Reroll items

Beli is the primary currency, earned from enemy and boss kills and spent on weapons, armor, Fruit Gacha rolls, and island shop items. The stat system uses allocatable points that can be reset via codes or paid items. Stat resets are among the most valuable code rewards, letting players reallocate without spending Robux.

Note: redeeming codes requires joining the Mvngo DEV Roblox group - this is a hard prerequisite. As of 2026, active development has ceased and concurrent players are near zero, but Sea Piece's 39 expired codes and strong search history continue to drive traffic.
