Master vessels are largely beneficial because you can put multiple bindings on one vessel to keep them with you all the time. Our master vessels come with proprietary spells that keep all the bindings protected from outsiders, in a harmonious environment, and allows dark arts & white arts to coexist; whether spirits, spells, or entities.
Once you have a master vessel we can remotely bind anything you purchase in the shop to your master vessel so you don't have to pay ongoing shipping fees for any bindings that you want on your master vessel, you will only pay shipping for bindings you want a separate vessel for.
You can find the master vessel listing here.
