Player-owned ports enhancer

The Player-owned ports enhancer is a possible item received from the Motherlode Maw's daily random reward if you have at least level 95 in all skills. You also have a chance of getting it by trading Wythien ten crystal motherlode shards, or you can talk to Wythien to convert an unfocused reward enhancer to a Player-owned ports enhancer, but it will only have 2 charges instead of 5.

When you are in the player-owned ports area, you can use the enhancer to get a reward from a port random event, including adventurer, captain, crew and voyage rerolls. It has five charges, and a charge is used whenever you generate a reward. It will disappear when all the charges have been used up.
