Monster Trainer:Underground market
The underground Market is the best place to get items in the Game. it is invitation only, so you need to get permission from Vincent before entering.
There are small versions of the market throughout all three classes, but the biggest is in Larpe (and it is hear were you will need the invitation).
The bussiness model of the underground market is a mystery. in some ways, it acts like one giant corporation and many branches. In other ways, the branches act like independently owned shops.....with mysterious partners. We could say the branches are franchises, but the main operation doesn't act like a franchise.
