3. Utilizing Special Currencies for Exclusive Items
In addition to Silver, you’ll come across a few other special currencies throughout your adventure that can be used to buy exclusive items to Skull and Bones Items help with stamina and overall ship performance.

Pieces of Eight: Earned by completing tasks in The Helm endgame mode, Pieces of Eight can be used to acquire rare items, including stamina-related upgrades and cosmetics from the Helm Black Market. This currency can be a shortcut to bypass some of the grind and get useful resources more quickly.

Sovereigns: You can earn Sovereigns by cheap Skull and Bones Items ranking up on seasonal leaderboards. Though they are mostly used for cosmetics, some of these items may also have secondary effects that improve your overall ship performance and stamina management.

Monstrous Tooth and Ethereal Ashes: These highly limited currencies are earned by defeating world bosses like the Kuharibu sea monster and the Maangodin ghostship. The items you can purchase with them often include exclusive upgrades and consumables, which may help with stamina management or provide powerful buffs during your voyages.
