Notes from author
This is a really powerful and fun build which I've been playing with for the last few days.
What a lot of people don't realize is that the Greataxe stun-locks like a beast. Its one-handed attacks are fast enough to chain, and they each deal 51 poise damage, requiring 52 poise to resist. In other words, the Greataxe, one-handed, is as menacing as a greatsword two-handed, but unlike post-patch greatswords the Greataxe is fast enough for stun-lock. And just look at that AR--594 one-handed.
Poise is crucial here. 105 is enough to resist two consecutive 2H greatsword R1s. What this means is that, as long as you're alive, you will be able to out-combo essentially everyone, including ultra greatsword users, as your Greataxe is faster.
The Stone Greatshield will tank Dark Bead like it's nothing. No need to roll here. Whenever you'd normally roll, now you should block.
Finally, the Greataxe actually will send some in-game foes flying. If you don't believe me, go knock around the skeletons in the graveyard by Firelink Shrine.
