Reskin is the Bartender and he's run out of beer so he asks you to bring him 1 of
Every kind of Flower, Mushroom and Berry and he gives you gold for them. But you can only bring
1 of each kind once. For his 2nd quest Refer to Theif Master for instructions
Also at level 10 you bring him an earth stone and he gives you 350gold for it.
Level 30 for Fire stone he gives you 750g (i think) For it.
Level 60 for Ice stone not sure how much for one of these (never turned one in)
Hell stone I don't know what level for one of this yet I think level 80 or 90.
