is there a way to get the starter ring
and more then 1 ring quickly coz i started in sandoria and didn't get one, is it allowed to transfer from a mule to get i read 3 in total on 1 character or not legal?
i saw it has 2 defence so im like wow i need it would help ALOT
and im new to ff11

there are two ways to get that ring.

one way is to make an elvaan character and have sandoria as your starting nation
the other way is to make any character and have sandoria as your nation. then reach rank 3 and buy the sandorian ring with 4,000 conquest points.

I doubt you can give it to your main from your mule on Nasomi. That is a thing in retail for some Rare/Ex items for characters on a single account, I believe.

hmm what is the fastest way of getting conquest points?

Trade crystals to the CP npc until your rank bar is almost full. Then trade him 8 stacks of water crystals to get a big boost to CP.

You can do this each time you receive a new Rank.

who is the CP npc?

there are many, they grant you signet and allow you to spend CP. usually found near an exit from town.

They also can give you supplies for an outpost (unlocks teleportation to that outpost).
