Notes from author
I've used this build for some time in the arena as well as in invasions, and it's probably the build I'm (infamously) know for.
The strategy is rather basic.
1. Cast Pursuers, and have them activate.
2. While the opponent is rolling around trying to evade the Pursuers or gets his guard broken by taking it, cast Tranquil Walk of Peace.
3. Rush up to your opponent and Dark Bead him.
4. In case you've missed and not managed to finish off your opponent, put on the Hornet Ring and Backstab-fish.
Obs. Now each of these steps requires practice. You need to know how to activate your Pursuers without having your opponent roll under them, and you need to know to learn how to toggle escape if you get stun-locked by the Curved Greatswords and the Ultra Greatswords.
However, you don't have to worry too much about the Roll-Backstab strategy as long as you execute steps 1 and 2. Healing is no issue either since Dark Bead practically one-shots anything at point-blank range.
In the Arena you'll pretty much rely on the same strategy, but resort to using your DST when you're out of spells. In this case, switch the Bellowing Dragoncrest Ring for the Hornet Ring.
