The most important thing to get in this game is a good weapon even as a caster at low levels. It is scary how long it takes to kill stuff with the weapon you get at the start.
So you need to farm Bone Chips and HQ Bear pelts. HQ cat pelts also. Also Spiderling Silk sells well also. Sell them in the EC tunnel. And you can get good buffs there for free also.
Hardest problem you will have is knowing where to go without maps. They used to be in game and took them out. Not Classic.
