I highly recommend naming a new character Ornstein and start with the Master Key for quicker access to both Bells of Awakening.
I also recommend getting your hands on the Black Knight Sword and two-handing that shit until you get the spear. If that fails, either the katana guy or Drakesword is your best bet for dealing damage to Ornstein in his second form.
Have fun slaying dragons and protecting the Amazing Chest from danger!
