I went inside of that church thats opposite of where you fight the Greenwood boss and figured out the trick to the lift that fat knight was trying to figure out. Took me 2 tries but I killed that ice sword wielder at the bottom and opened up the Road of Sacrifices. I noticed he was talking from the path in between lifts where you have to roll onto a platform as it's moving. I go there and talk to him and see this gigantic fire dragon looking monster with a club and pretty much go . Even the fat knight said to fall back...but there was nowhere to go in between the lifts but that area and certain death so I pretty much had to suck it up and go down there. My plan was to run past it somehow but I actually got hit twice (but didn't die ), then I noticed the fat knight was behind me trying to fight it and taking quite a few hits. I wasn't gonna let my man down so I figure if we gon die down here, we gon die together. Maaaaaaaaaan that motherfukker only looked tough as hell. Couple of slashes from my Broadsword (that's only +2 at the moment) and he was dead and I got a fire gem + 5k souls from it.
