Amazing segments of beauty in an otherwise crapsack world.
As expected, all the prisoners, guards and dogs in this prison are hostile hollows. They're easy enough to deal with using basic field tactics though (like flanking and luring). I am once again jumped by the Eagle Knight here, and manage to hurt him significantly before having to flee. Fortunately he gives up the chase and vanishes - at least he didn't kill me this time!
Lucatiel has followed me here it seems, purely to give me a ring of some sort. Again, she doesn't offer to assist in any other capacity so I leave her there and find my way into the "main" prison block of Sinner's Rise - from the top I see some big winged creatures in the distance but my path leads me back down to sea level. After slaying another shiva knight I come to a massive prison of "the Lost sinner", a giant man who was so thoughtfully locked away -with- his great sword.
If he wanted invisibility he should have copied those mist bastards.
His first move is to kill all the lights with a single swing but I can still see him and his telegraphed moves just fine. I slay him on my first attempt and collect what happens to be the first of the four "great" souls. Cool. A bonfire behind him warps me back to Majula where I spend his soul purchasing the interesting rings sold by the talking cat.
