The new story dungeon is Aetherblade Retreat, where players invade the Aetherblade base, fighting pirates and taking on the Aetherblade Captain and First Mate bosses, with special drops and caches, including a First Mate Horrik miniature companion and a stylish monocle.
The update also includes a new skill, Mortar Mastery, which includes increasing mortar blast radius, damage buffs, reducing skill recharge, and even adding a new skill, Mortar Barrage.
