Pockie Pirates Shells

Equipment on Pockie Pirates can be embedded with shells. There are 7 different types of shells that offer different stat boosts, also each shell comes in different grades and the higher the grade of the shell the higher bonus stats it provides. Players can also synthesise lower level shells in order to create a single higher level shell.

The quality of the gear will determine how many shells can be embedded into it, although only one of each type of shell can be embedded into a single piece of gear. Players can also remove shells via the embed interface. Shells can be obtained from the underwater treasure system as well as other activities.
