You can try using a bow and hit-and-run tactics until you are stronger. I rarely bought equipment, since I usually found better stuff while exploring or dropped by monsters.
If you drink a shadow potion and use your spin attack near (but not directly on) a creature, you will hit it without turning visible.
I would get your agility up higher (check your chance to hit and be hit in the stats pane, as popup info hovering the cursor over your offense and defense). While in Verdistis, you will get a quest to steal some some lockpicks. If you started the game after installing the 1.34
patch you can return them and then buy them back; if not just keep them. They are unbreakable and give you an agility bonus.
