Pirate Raid: schedule, free fruit and rewards

Pirate Raid is an exclusive event in the Third Sea that triggers every 1 hour 15 minutes at Castle on the Sea. A horde of ordinary enemies from the First Sea and Second Sea land on the castle, then a final opponent much more resilient than the others appears. Whoever deals the final blow to it leaves with a random Blox Fruit, making it one of the main ways to obtain a fruit without going through the Dealer.

How to get it

Head to Castle on the Sea in the Third Sea and wait for the 1 hour 15 minute cycle. A system message announces the pirates' arrival 20 seconds before the raid begins - there is nothing to pay or summon.

How It Works

A horde of non-boss enemies from the first two seas appears on the castle. Once the wave is in place, a final enemy much more resilient than the other pirates appears - this is the one that carries the real reward.

If the players present fail to defeat all the pirates within the allotted time, the event ends on its own with the message "The pirates have stopped raiding."

Rewards

A random Blox Fruit for the player who deals the final blow to the tanky enemy (note, this is the final blow on this specific enemy, not the last pirate still alive)
100 Fragments for any player who has killed at least one pirate, distributed once all enemies are defeated
Completion of the second trial of the Tushita Scroll, Sense of Duty, from the Cursed Dual Katana puzzle, once all pirates are defeated and provided you have killed at least one
NPCs killed can also drop Materials

Trivia

This is one of the main ways to obtain a Blox Fruit in-game.
The first fruit obtained by dealing the final blow also unlocks the Raid Boss title, number 160.
To encounter a Pirate Raid, look for a Full Moon server: the raid generally arrives 15 to 30 minutes later, or 10 minutes after the full moon ends if it's the first one.
The event attracts many cheaters: the source recommends doing it on a private server.
