Have you managed to beat the Black Knight yet? There's a rather obvious trick to it, but it's easy to miss. I'm blacking it, so anyone who has not beaten the Black Knight, don't highlight it.
There are 3 spots on the ground that give + 10 def. He stands on one, so pull him away.
Oh, but don't forget to kill Levail and get the Wishblade first.
When I write Fact: in one part of the post, and opinion: (or a similar word), it's not because I can then say "my opinion can't be wrong". It is to inform what part is pure facts, and which part I try to draw a conclusion in.
