I'm currently the highest rank with the Twin Adders, have 50K seals and have nothing more to buy. I want to change to a different GC, but I'm not sure what I lose with the conversion. Do you keep your seals to spend on the new GC (If you do lose them, could I buy up some skill point respecs to use later on?)? Will the weapons and armor I bought from the Twin Adders still be useable or become locked? What about barding and the minion? Anything else?

Thanks!
