Someone on the official forum gave me this awesome tip when I asked about finding a specific item (the cat bank, which I eventually found in a shop):
I suggest jump farming the puppy cave. This means you go inside the cave, look at the items that are within immediate view, take any you want then leave and come back in. The puppy cave is always random, so this is a time efficient way to get certain items (especially low level spellbooks)
I've been doing this and finding all sorts of fun stuff, including a guillotine which I'm terrified to use for fear it's a suicide machine of some sort, and loads of spellbooks.
The official forum is pretty cool, though you usually have to wait a day or so for an answer because there are only a few people who know everything about the game.
So I'm having pretty good luck with a Warmage, got him up to level 4 and managed to avoid the ether twice. Highest I've gotten is level 5, but then they got riddled with ether effects and stopped being worth playing. I finally have my first Cure Corruption potion with this character, too, and he hasn't died yet! Hooray!
Edit: Oh, by the way, the official forum has this advice on getting seeds: You can worship Kumiromi, then carry food around. When it rots, there is a chance that you will get seeds.
Unfortunately, I have no idea how to worship Kumiromi. Maybe I'll go ask, unless one of you guys knows...
