Just grind a good weapon (i used the hunters saw cleaver +6) and the witches are only 3 or 4 hits. then once u get the shortcut to the boss just start sprinting there and avoiding the witches
also when u fight the boss its pretty easy once u find a good strat on google
thanks for the help, but I have cleared this area
oh ok good luck on martyr lagarius r.i.p.
