Hello Pirates,

We've completed another Ramadan on the seas of BOS. We wish everyone a joyful Eid al-Fitr and many more holidays filled with health and happiness. Hoping our players spend a meaningful holiday with their families and loved ones, we have scheduled our holiday event for after Eid.

To honor this special day, we are also organizing an event on the seas of Battle of Sea. Alongside the event, there will be event rankings and special event missions waiting for you.

#Important Notes
-With the event, the Pirate Trader will offer items that can be purchased using event keys: Fireworks (13 keys), Gunner's Eye (15 keys), and Sharpshooter (15 keys).
-Players who deal the final blow to the NPC ship named Bonesail Admiral will have a 10% chance to obtain the Bonesail design.
-For the unlucky ones, the Pirate Trader is prepared. Those who can't win the Bonesail design from NPC ships can purchase it from the Pirate Trader for 80,000 event keys.
-The Bonesail Admiral design will be available in our web store until 12:00 PM (noon) on 09.04.2025, just like the previously limited-time "Sun Hunter Admiral" design.
-Additionally, for those who wanted to get the Sun Hunter Admiral design but couldn't, that design will also be available in our web store. The designs will appear in the store with the start of the event and will remain available for purchase until 12:00 PM (noon) on 09.04.2025.
