Upgrading Krowaz

[RedBullEnergyDrink]

If i buy krowaz +1 (rogue) do u need anything special to upgrade or is it just like anything else, just use bus? or do u need like sometype of special stones like when manufacturing?

and is their anything special with it like does it seal to ur acount or anything like that, i know theirs bonuses when full set

you just upgrade it with a bus, once you equip the armor it seals to your account you can take it off but you cant resell it nor can u trade it.
