Arena Breakout’s B.Duck sailing event: weekly missions, postcards and rewards
The global mobile event runs November 2–19 (UTC+0), with weekly missions providing Mystery Boxes to send B.Duck sailing.

Arena Breakout’s global mobile event Let’s Breakout Together links weekly missions to a shared B.Duck sailing journey. The official dates are November 2–19, in UTC+0.

Complete weekly missions during the event to earn B.Duck Mystery Boxes, then spend them to send B.Duck sailing. As the number of B.Ducks across the server grows, the flock gradually reaches new waters. Check the Break Out Diary to claim rewards for the corresponding progress.
Each B.Duck discovers two sets of supplies in succession: these can contain Koen, B.Duck Tokens or postcards, so every type is not guaranteed. Collect six B.Duck postcards for spray rewards, and exchange tokens for appearance rewards at the Ducky Supply Station. The announcement does not list the individual missions, exchange catalogue or exact closing hour.
