Just an update, the rings are "One of a kind".
So you can equip one at a time.
But still, with four different rings, that could make some nice stats.
Also, I checked the Ariant cab.
Vic > Ariant is 8,500 mesos, and only useable if you're above level 21.
Ariant > Vic is 12,000~14,000 mesos.
Ariant > Sahel 2 (Magatia) is 1,500 mesos.
Edit:
Seems like eMS is gonna let us decide one of our patches, I hope that my thoughts are right and the last option would be an eMS exclusive area.
If not I want China <3
