another good thing to do or what i do is find a cave like the one next to where u first start the game when u come out of the sewer u go right and u will see the cave go in and clear it out find a create or box/chest and drop all ur shit in there and just keep going back and droping all ur stuff u want to sell into 1 cave or house u buy whatever then u can go back anytime and pick up stuff u want to sell as the shop keepers only have so much money at a time and they are only open in the daytime hours and sometime u will find alot of stuff at 1 time so theres a tip another 1 i did was to build ur skills up real quick is to summon a monster/whatever u have and then say u want to build ur sword skill up u just slash the hell out of them and u can do it over and over same thing with say attack spells like fire ice or whatever
