Notes from author
A build I designed for coop with a friend of mine. The strong attack on Ricard's Rapier combined with Sunlight Blade means you will have massive damage outputs on a boss. Silver Knight Spear is utilized to clean trash mobs on our way to the boss room. Its range makes it very effective when used in tandem with the shield. The wide sweeping arcs of the 1 handed R2 make it even more efficient at clearing trash mobs.
The silver knight shield provides excellent stability, a high defense, great resistances, and looks very nice with this setup. I do also sometimes swap it out for Sanctus, both for an alternative look, and for some free healing while being summoned as a gold phantom.
I keep a Darkmoon bow with Moonlight arrows in my inventory for Ranged support where needed. However this along with Sunlight Blade does mean we will have to kill Gwyndolin. Hopefully you don't mind Darkmoon invasion too much.
This brings me to my next point, PvP! This build is equally as strong in PvP as it is in PvE. If you want to PvP with this build, I suggest swapping Heal with either Tranquil Walk of Peace or Replenishment. Great Lightning Spear can be swapped for Emit Force or Magic (or Great Magic) Barrier.
