This is one of my all-time favorite weapons, once I got ahold of it in DS2 it's my weapon of choice, plus I was a huge fan of Creighton. I created a pretty Gnarly Herald build with this weapon, Raw+10, for higher physical damage, and due to there being no faith stat for it, use lightning blade to increase the already present lightning damage, and scale the buff with your faith. Having a 110 buff chime is also great. My miracles are: Tears of Denial, Sunlight Spear, Bountiful Sunlight, and Lightning Blade. At 3 swings of my Dragonslayer, I do 1k damage, typically. I can swing it 6 maximum times, making my maximum damage around 2500 with warcry active as well. Wielding this one handed is the way to go.
