Now I'm somewhere around level 11 and I have so much money that I don't know what to do with it.Yes, there are many useful fountains and wells in A1. I frequently use the one along the road (separated by one space of water) --- that increases your HP by 100. Another one increases your Might by 20, a muddy hut on the peninsula increases your SP by 100 and another (hidden somewhere in the mountains) increases your level by 30.
But Orcs are no trouble even without those boosts. (At least I killed them fairly easily.)
