This build is centered around the usage of glaves, but can be turned into a quality build in a snap.
Rings: Chloranthy Ring (For endurance regen), Pontiff Right Eye Right (For added damage in each hit), Havel's Right (For if your armor becomes too heavy for a fast roll), and an Estus Ring (To get more from your drinks)
PvP: With this build, your going to have a slow attack disadvantage, but the glaves 2nd attack (A form of AOE) is where its at. You want to play passive till needing to be aggressive, only looking for open spots to attack. If you miss your first attack, see if there's a chance for your 2nd attack to hit. If not, disengage and wait again for another opening. If you land your 1st attack, then go for a 2nd one as quick as you cam, since its easy to dodge it if they have a small window to dodge through.
PvE: This is more useful for crowd control and on bosses that have some form of minions or crowds. Use the 2nd attack to clear a good portion of the minions, and once your safe, attack the boss with both the 1st and 2nd attack. The Estus Ring should help you when you get too low, since if your in coop, your Estus usage is in half, so taking damage is more dangerous.
