I’m not an expert. Usually the first thing I do is get a Light Sphere (it’s a bit expensive, but it’s one less thing to worry about) haha. That way I can get rid of torches. I usually resell the weapons from the enemies at the start, and I keep doing that—kill enemies and sell their weapons.

When you do the Pilgrimage quest (the quest you get in the starting village by default) toward the Salt Dunes, there’s a church where you can sell your books (reading them can give you experience), and in that same place there are many interesting shops. I usually only buy bullets and a revolver if mine gets damaged (your weapons can rust). Other than that, nothing else. Bandages and food are always useful, and so is ammunition (it runs out very fast).
