Players in possession of the key item Rhapsody in Azure and have proceeded to a certain point in Assault and mission conter may now purchase the following key items from Curio Vendor Moogles stationed in the three nations.
Assault
PFC Wildcat Badge / SP Wildcat Badge / LC Wildcat Badge / C Wildcat Badge /
S Wildcat Badge / SM Wildcat Badge / SL Wildcat Badge / FL Wildcat Badge
Players must be in possession of the previous rank's wildcat badge and have met the prerequisites for undertaking the appropriate promotion quest in order to purchase these items.
so you still have to do your assaults but you don't have to do promotion quest, just buy KI and I thought 10 min assault tags made it easy.
