nice, yeah i guess the fact that u can topple him and knock him off the edge makes 4 a pretty easy spar
after brown town londo
u might wanna save the demon ruins under quelaags lair for last since they are probably the longest in length according to the number of boss battles and trek to the actual lord soul stealing punk @ the end of it
4kings arent fun, but the area surrounding them is pretty neat (u need the artorias covenant ring, which enables u 2 enter the abyss and take them on; acquired from another boss @ dark root garden)
skele catacombs + tomb of giants isnt that bad, except tomb of giants is pitch black and full of horrifying skeletons much worse than u normally encounter, boss here is a pain if u dont rid of skeles 1st
dukes archives is accessible in anor londo actually, and a place familiar w/ invasions
