Notes from author
This is a modified, newer, and more effective version of an older build I made way back when I really had no idea about what I was doing...
The core idea behind this was to use all 3 forms of magic: Miracles, Soul Spells. and Pyromancy, alongside the Moonlight Greatsword. With 5 attunement slots, you can spice up your magic while still keeping ranged attacks.
With 45 DEX, you get that speedy castings, in tradeoff for 16 strength. You have less weapon variety, but you can buff 'em with basically anything in the game.
Rings: RoFaP *Mandatory*, Wolf Ring *Changeable*
With 44 endurance, you maintain that fast roll with only RoFaP, leaving an extra slot for whatever you need at the moment.
Without Wolf your poise is stuck at 22. Wolf lets you take a black flame to the face with 62 poise. Black flame: 61 poise-break potential. Eat that shit while still looking good.
Did I mention you may or may not look intimidating as all hell? That skull face has been in all renditions of this build and it's still here. I made a point to make it actually look good this time too.
Conclusion:
Use all three forms of magic while still being quick and look like a badass while doing it.
