To anyone that is thinking of just getting the weapon: a copper voucher is worth 1,000 sparks, isn't it better to get 10 vouchers, get the weapon for 7,000 sparks (7 vouchers) and save the other 3 copper vouchers for something else?
Given via mail to anyone who logged in between Sept. 10-17th 2014.
Can be redeemed for any one Eminent weapon, or one of the special NQ items from Login Campaigns (eg: Chocobo Masque), or 10 copper vouchers.
