Picked up Quelaag's Furysword (and upgraded it to +5) with my Dex Pyromancer and it has easily become my favorite weapon with her. Moved from her Fire Falchion +5 to a Black Knight Sword +5 simply because it seemed to demand usage, but I murder more quickly and sweetly than anything else previously with my new baby. Been milking Darkroot Garden for Forest Cops and NPCs, getting a 3:1 ratio in terms of killing:being killed. So exciting.

How many more souls do you need for your Lordvessel, Jowy? Nito's is probably the easiest to obtain. I pray you have the strength to overcome the other bosses.
