Notes from author
Between the dual wielded Claws, the 2-handed Zweihander, and the powerful Pyromancy, this is truly a build fitting of the name "Daemon."
Variations:
One can switch out vitality with attunement for up to eleven slots, which would bring vitality down to 50 and attunement up to 58. After that, the vitality is just too valuable to give up.
The pyromancies used are, for the large part, variable. The only ones that you really need keep for this build are Great Chaos Fireball, Chaos Storm, and Power Within. On the opposite spectrum, you maybe inclined to double up on one or more of these after you reach NG+. Given the limited castings of the Chaos spells, this could be quite useful.
The Wolf Ring can be switched out during play allowing you to be more flexible. But, don't forget that removing this ring means leaving you with no poise and no shield to block with. I would advise against this unless you are relatively certain that the enemy won't be able to lay a hand, talon, fang, etc. on you.
And as for the covenant, you can pick whichever you like, as this build doesn't rely on any particular one. I simply chose the Cat Covenant arbitrarily.
