Equipment is widely available throughout the lands of Arcadia. The listings found here are modelled on what is freely available throughout the territories of Caledon.
You are almost guaranteed to find everything listed here for sale in all the major cities. The towns and villages will only have stock of various items.
The prices don’t vary much from settlement to settlement, usually no more than 10%-20% in either direction. If there is a glut of stock you’ll get certain items cheaper, where as rarer items will be more expensive than what is listed here.
The prices are affected not only by it’s availability, but also by local climate, terrain and craftsmanship.
