Hello My name is INocturnalI and i am here to add few tips about Gathering Mythril Ore from the guide below

Because of the new added Guild Base server, now we can gather 2 server at a time or 4 if you use season char. And the respawn of that ore are every 6-10 hours.
Also, when i tried to gather on every server, the only server with exhaust resource is server S2.
