Finished play through 25 this morning and now I am so chewing on my controller till Dark Souls 2's release date.
In my search for more info without spoilers I found the a pretty annoying guy on youtube but the info dump makes it worth it. A lot of it is guessing on his behalf but based on his hands on experience.

Part 2: (Bit of spoilers but right at the end and easy to skip.)

If you know anything else useful please post it here but PLEASE NO SPOILERS!!
