Dark Armor or the Paladin Armor sets due to the good defense/weight ratio.
Rings= Ring of Favor and Protection is a staple for this set, and it should be paired with either the Ring of the Sun's Firstborn or Cloranthy Ring as a focus on miracles/melee.
Left hand Items= Main: Giant Shield Secondary: Darkmoon Talisman
Right Hand Weapons= I personally like having a +10 Divine Halberd but your main can be any preferred +10 divine weapon used one handed to make use of the shield.
For your secondary you need a good enhanceable weapon to be used with Sunlight Blade.
Miracles= Lightning Spear, Great Lightning Spear, Sunlight Spear, and Sunlight Blade.
Gwyn Lord of Cinder. Other than that you can defeat any boss without need of help, although it doesn't hurt to have friends. I usually PvP in Darkroot Garden. The basis of the build is to do the majority of your heavy lifting with your shield and divine weapon. I switch to the spears when i want to stay away from enemies or just out of reach, or i know the target has low lightning resist. The Sunlight blade is used on your basic +15 weapon against tough targets or bosses (other than Gwyn)
