The Tide Keeper Blox Fruits is a Level 1475 boss located on a hidden platform behind Forgotten Island in the Second Sea, with 105,000 HP and a 15-minute respawn timer. He drops the Dragon Trident at 7.5% and the Water Key at 40% โ the Water Key being essential for unlocking Sharkman Karate, which is itself a prerequisite for Godhuman. He is one of the most important late Second Sea bosses for progression.

Tide Keeper โ Level 1475 Second Sea boss behind Forgotten Island. Drops Dragon Trident (7.5%) and Water Key (40%). Key for unlocking Sharkman Karate and Godhuman.
He is not on the main part of the island โ he is behind it on a separate platform.
Forgotten Island is one of the easternmost islands in the Second Sea. It has a distinctive green jungle appearance. Sail toward it from the Kingdom of Rose โ it is a fair distance out and is easy to miss because it looks similar to other green islands at range.
The main Forgotten Island area has regular enemies. Tide Keeper is not here. Navigate your boat around to the back of the island โ look for a small separate rocky platform set apart from the main landmass.
Sail all the way to the back (far side) of Forgotten Island and look for a raised platform structure. Tide Keeper stands on this platform. He is clearly visible once you clear the main island's edge โ green pants, golden skeleton shoulder pads, yellow shoes and green hair.
The Forgotten Quest Giver NPC is on the main island area near the edge closest to Tide Keeper's platform. Accept the quest before fighting โ defeating him without an active quest means no Beli or EXP reward from the quest board.
Every item obtainable from defeating Tide Keeper.
| Reward | Drop Rate | Type | Use |
|---|---|---|---|
| Fragments | Guaranteed | Always | Awakening moves and fights styles |
| 51,000,000 EXP | Guaranteed (quest) | Quest | Level progression |
| 12,500 Beli | Guaranteed (quest) | Quest | Currency |
| Water Key | 40% | Common Drop | Unlocks Sharkman Karate from Daigrock |
| Dragon Trident | 7.5% | Rare Drop | Legendary Second Sea sword |
The Water Key unlocks Sharkman Karate from the Daigrock NPC inside the underwater cave at Underwater City (Second Sea). Sharkman Karate requires Fishman Karate at 400 Mastery first. Getting the Water Key is the primary reason most players farm Tide Keeper โ it is on the critical path to Godhuman.
The Dragon Trident is a Legendary Second Sea sword with sea-themed moves. At 7.5% drop rate it takes an average of 13โ14 kills per drop. Most players pick up the Dragon Trident naturally while farming for the Water Key since the Water Key drops faster. Full Dragon Trident stats are in our Dragon Trident guide.
Two key mechanics make this fight harder than his level suggests.
Tide Keeper deals up to 2,000 damage per hit at close range. Stay outside his melee range and spam long-range attacks. Ranged fruit builds (Magma, Venom, Light, Flame) are all effective without taking significant damage.
Awakened Magma โ walk on water near the platform, sustained lava DoT. Light โ fast M1 speed at range. Venom โ DoT keeps damage ticking while you stay mobile. Any fruit with good range works since Tide Keeper does not have strong ranged attacks.
Awakened Buddha transform + any fighting style works reliably for solo kills. The size bonus makes every AoE hit connect easier and the defense boost reduces incoming damage significantly. Fastest consistent solo kill method at Level 1475+.
Two or more players dramatically speed up Tide Keeper kills. Split the quest, rotate attacks, and server hop together. A team of three can complete a full Dragon Trident grind session in a fraction of the solo time required.
For context on the Sharkman Karate chain that the Water Key unlocks โ and how it connects to Godhuman โ see our full fighting style progression guide. Tide Keeper is the gating boss for one of the most important style prerequisites in the game.
Where he fits in the full late Second Sea progression.
| Boss | Level | Key Drop | Drop Rate | Why Farm |
|---|---|---|---|---|
| Cursed Captain | 1325 | Ectoplasm (currency) | Always | Midnight Blade purchase |
| Awakened Ice Admiral | 1400 | Hidden Key | ~5% | Rengoku sword access |
| Tide Keeper | 1475 | Water Key (40%) + Dragon Trident (7.5%) | High/Rare | Sharkman Karate unlock |
| rip_indra (Second Sea) | 1500 | Portal to Third Sea | Always | Third Sea access |
Tide Keeper sits right before the rip_indra fight and Third Sea transition. Players typically farm him for Water Key to unlock Sharkman Karate before pushing to Level 1500 and completing the King Red Head questline.
Why the Water Key is the most important thing Tide Keeper drops.
Sharkman Karate is one of the five fighting styles required for Godhuman. The full chain: buy Fishman Karate from Gyatz in Underwater City, grind it to 400 Mastery, obtain the Water Key from Tide Keeper, then bring it to Daigrock in the Underwater City cave who teaches Sharkman Karate for 2,500 Fragments.
At 40% Water Key rate, most players get it in 2โ3 Tide Keeper kills. The bigger bottleneck is reaching 400 Fishman Karate Mastery before the key is useful. Plan this grind during the same time you are leveling toward Level 1475 to access Tide Keeper.
Tide Keeper gives 51,000,000 EXP per quest โ more than most Second Sea bosses. Combined with Dragon Trident and Water Key drops, he is the best multi-purpose boss in the late Second Sea. Players at Level 1400โ1500 should chain Tide Keeper and Awakened Ice Admiral quest runs for the most efficient combined EXP, Beli, and key drops before the Third Sea unlock quest.
The Dragon Trident is the other major Tide Keeper drop at 7.5%. It is a sea-themed Legendary sword with two moves โ both carry a water and dragon aesthetic fitting the Tide Keeper boss theme. Most players who farm for the Water Key accumulate enough kills to also get the Dragon Trident in the same session. At Level 1475, the Dragon Trident is a strong sword option before transitioning to Third Sea weapons.
