Location: Catacombs of Carthus
Bosses: High Lord Wolnir
What can I say, it went surprisingly well and smoothly in the catacombs. Even the boss gave up his soul right at the first attempt. But I suspect that I missed the tome that you can collect from him. I thought I could do that when he was dead, but unfortunately I was immediately teleported out of the boss area. Hmmm… :-/
