Notes from author
Seeing so many attempts at making an Ornstein build that weren't very well thought out, I decided to make a better one. Obviously, he has the Ornstein set+Leo Ring, so keep your talisman in the second off-hand slot, so you can parry with your fist. RotSF is great for Miracle bonuses, but you can switch for a Ring of Steel Protection, as I know playing without a shield is difficult (cite: a very fun Lord's Blade cosplay). Keep a hefty supply of repair powder for your spear, as the one-handed heavy unleashes a lightning blast the reduces durability. Join the Princess Guard covenant (for some reason, people put him in the Warrior of Sunlight?), as he IS one if the Princess' main two guardians. Miracles include the standard WotG and G. Sunlight Spear, along with Replenishment for mid battle passive healing and Karmic Justice for bankers or particularly difficult PvE. As the build has no shield, be very aggressive. Keep their guard up and make sure they can't get too many hits in. Make sure your parry skills are up to par, as well. Don't let the Leo Ring go to waste. Don't be shy with WotG, it will save your life. As much as Lightning Spears are the face of Miracles, scarcely use them, as they are easily dodged. Cast Karmic Justice if you are able at the beginning of a PvP if possible, and try to be secret. Even though it's useful, not many people utilize it, so it will be a surprise, as well as an opening for a two-handed heavy combo to launch your enemy, with a follow up one-handed heavy that will basically tear apart most all players to the point of near death. This is a potentially powerful build if you know how to parry well, and can keep the pressure on your enemies.. It's biggest downside is it's lack of actual defensive abilities, aside from blocking with the spear, so watch out for that.
-Good Luck, and Happy Hunting.
