Castle on the Sea

How to get it

In the center of the Third Sea, accessible by boat when you arrive in this sea. Talk to Set Home Point to respawn there. Three portals on site allow you to then travel to Tiki Outpost, the Floating Turtle Mansion, and Hydra Island.

What you can find there

• About twenty NPCs: Remove Blox Fruit, Aura Editor, Mysterious Scientist (microchip buying/trading), Elite Hunter, Player Hunter, Sharkman Teacher, Dark Step Teacher, Water Kung Fu Teacher, Martial Arts Master, Boat Dealers, Butler, Sabi, Sealed King, Set Home Point...
• No local enemies outside of events
• The starting point for Third Sea raids
• rip_indra True Form (Raid Boss Lv. 5000)

Pirate Raid

Every 1 hour 15 minutes, a horde of enemies from the first two seas lands on the island. A very tanky enemy brings up the rear: whoever deals the final blow to it wins a random fruit, and every player who defeated at least one pirate receives 100 Fragments at the end of the event.

Summoning rip_indra True Form

• Press the Aura buttons on the island with the corresponding legendary Aura color: pink button (Winter Sky), white (Snow White), and red (Pure Red).

• Then place a God's Chalice on the pedestal to the right of the entrance: the Lv. 5000 boss appears.

Good to know

• Portals: the orange one (left) leads to Tiki Outpost, the middle one to the Floating Turtle Mansion, the one on the right to Hydra Island.
• Mansion and Hydra Island require defeating rip_indra True Form at least once; Tiki Outpost requires defeating Tyrant Of The Skies.
• Like in the Second Sea, the Mysterious Scientist manages microchips for launching raids.
