I have been using a raw Astora Sword but I was thinking of upgrading to Dark Sword since so many rave about it. Does it only work as Heavy or Refined? Would 25 STR and 25 DEX be enough to make the weapon work well? Every other game in the series I had  a clear path to what weapon I wanted in this game I just feel a bit lost. Thanks for any help.
