Welcome back.
I continued my trolling in the top-part of Sen's Fortress (I believe the lower part is hard enough as it is, so I'm showing some humanity) and made quite a few successful kills. I also really like this environment to fight in, as it is really diverse and you can be creative in tactics.
Afterwards I gave Anor Londo a shot, but invading here is pretty hard. Once again I chose to invade the part right after the 2 infamous archer knights, as the area's before that are frustrating enough. I've made absolutely 0 successful kills in about 20 tries, mainly because pretty much everyone has a summon or 2 as bodyguards. A few times I got close by ambushing the party while they were fighting the Royal Sentinels, but no luck. I'm still amazed by how well the camouflage spell works.
