What class did you make?
I made the Thief to start, but I have found that you can emulate any class you want just by equipping the right equipment. I chose the Thief for the master key.
I just finished Anor londo on my second playthrough. Been doing A lot of PvP but Still realy enjoy playing the story. Im probably gonna finish the onion man/solaire story lines this time. Last play through I didnt really explore a lot of the back stories.
I have followed many of the story lines, but have a couple meetings left for the onion head clan. I am looking to get the thorn armour now, but I keep getting invaded by jerks. Most who invade have done the dragon head cheat, and are very difficult to fight.
