Uses an awesome armor combination and a combination of both light and heavy weapons and, of course, uses hexes.
Use a Dark Longsword +10 in RH1 slot and Dark Crypt Blacksword in RH2 slot. Use a King's shield (any infusion is fine) in LH1 slot and a Dark Black Witch's Staff in LH2 slot.
Head: Prisoner's Hood
Chest: Armor of Aurous
Hands: Gauntlets of Aurous
Rings: Third Dragon Ring, Royal Soldier's Ring +2, Ring of Blades +2, and the Abyss Seal ( this makes the hexes deal even more damage than they already did ).
PvE: Two slots of Dark Orb, Resonant Weapon, and Great Resonant Soul.
PvP: One slot dark orb, Great Resonant Soul, Resonant weapon and Scraps of Life
If you want, you can replace the Crypt Blacksword with a lighter greatsword and be able to replace the Royal Soldier's Ring with a Southern Ritual Band ring +2 in order to obtain 3 more attunement slots.
