What are resins?
Resins are how we can craft (in essence, buy) trophies. You simply use an enchanting rod (bought in Stronhad or Atlimus for 600g) and place a stack of at least 1 resin in the top left hand corner only. The result will be a stack of either combat or spirit (random within limits) trophies at the value of 33.33g/1k exp, with the exception of the lower value trophies, and a weirdly priced resin or two that give slightly less exp for your gold. Resins can be bought in the General Store of each town, or gotten from dismantling items.
