just finished catacombs, oddly enough. finally found a path from the secret bonfire to the room full of pinwheel skeletons which put me on a ledge above them so I could pick them off with greater soul arrows. after that I spent a little more time exploring sen's fortress and leveled a couple of times, but I was basically procrastinating because the archers in anor londo scare me too much.
still not having much luck with pvp. last night I played for about 2 hours and activated my blue eye orb every time I got an "invasion failed/cancelled" message and never managed to find a world off the guilty to join. in my case it's probably location, being a large english-speaking country on the doorstep of asia limits the pool of available players somewhat.
