Just beat both the ghost chariot and skeleton lords, i'm not really having much trouble with the bosses, haven't died more than three times on a boss and the was on the pursuer as I was pretty under-leveled...been doing alot of co-op since I'm apart of that covenant, seemed ALOT of people needed help with the Ruin Sentinels and Gargoyles, I was getting summoned in seconds after using the white sopestone.
