Notes from author
It is intendend for PVP and PVE.
I tried many weapons before coming to Demon Greataxe; I chose it because it deals ton of damage while being relatevely faster than an hammer (I tried Smough one,its good but not enchantable) or an UG (I've used the Dragon Greatsword to clear first NG,rushing it from the Shrine; good but doesnt scale)
It is recommended to pump stamina to its softcap cause attacks will drain a lot of it; also helps shield blocking)
I also recommend having a full upgraded Havel Greatshield if the enemy deals magic damage.
SMG on Artorias shield is quite OP,it almost drains no stamina.
