More exploring, and also making new weapons from cheap weapons with easy-to-obtain souls to sell for huge profits. Hurrah!
Worked my way through the top-right of the map, finding some harder baddies to kill (most of the others die in one or two hits now so were becoming a bit easy), but then made the mistake of walking through a Magic Sealed door and into a boss – a giant eel, underwater, who fires ice things.
I died. Pah.
