Hex and melee build with damage!!!
Right hand: dark or lightning curved dragon greatsword+5, blacksteel katana +10
Left hand: slumbering dragon shield+10, (or archdrake shield for pve) blacksteel katana+10, arch drake staff+10
Armor: Alonne knight captain helm, alonne knight captain chest, alonne knight gauntlets, alonne knight leggings
Rings: ring of blades+2, Chloranthy ring+2, third dragon ring, royal soldiers ring+2
Dark weapon, dark orb
Pve: use archdrake shield, anything boss or tough enemy weak to dark use dark orb and dark weapon on curved dragon greatsword( either element I recommended) to do more damage, or blacksteel katanas for faster approach… Win.
Pvp: if enemy is caster- use curved dragon greatsword strong attack to throw off gaurd, then switch to katanas to attack fast,
For melee- (slow weapons) use greatsword strong attack when far away then switch to katanas to counter there slow speed. If fat rolling use dark orb
(Fast weapons) use greatsword and shield, if you're good at parrying; parry, if not block hits fast ( don't hide behind your shield before they gaurd break you!)use katanas in sticky situations only, usually you can 2-3 shot enemies with fast weapons (because they usually have light armor) but the katanas help when in trouble.
Finally, use dark weapon on anyone with light armor that isn't Hexers armor, and on Havel monsters, they seem to take a lot of dark damage.
Don't forget to bow before every battle it is the proper way to play the dark sentinel, the only way…
