Notes from author
This build is specifically crafted to take advantage of a mix of standard dex-int tactics to create a new look at what you can do in PvP.
Using the wonderful fact that the Obsidian Greatsword is enchantable and requires fairly low strength, this allows for a very fun and interesting build. Anytime you combine a large weapon with the hidden weapon sorcery, fun times ensue, even more fun for you when suddenly you stab the ground for an AoE that they never saw coming. The Painting Guardian Sword is for those times when you need to dish out damage buffet style, combine with Crystal magic weapon and great scaling for dex & int, and enemies will melt before your wrath. The rings are hand chosen to make absolutely sure you are never without stamina, increasing both the pool and the regen. The mask is also there to keep your stamina high, but you may choose to sub in the Crown of Dusk in order to boost your crystal magic weapon rather than your stamina regen, personal opinion really. the armor is simply a mish mosh of whatever can be combined to look good while still retaining Chester's Long Coat, disregarding poise items in lieu of aesthetics... i don't think single digit poise is worth looking stupid over, again, personal preference.
Have fun with this build and enjoy many a shocked opponents who never saw the Obsidian Greatsword coming. ;)
