Hybrid build so pyro makes up for some of our lost stats in faith. Attunement can be 16 without issue. Expensive build but pyro is optional so it gets cheaper if you leave it out. If you do drop pyro I would run TWoP/Karmic or Great Magic Barrier to deal with Dark Bead in PVP.
Wolf ring or Hornet depending on what you're comfortable with/facing for PVP. Ring swap is your friend.
