Notes from author
An attempt to maximize stamina regen for the purposes of relentlessness.
Cloranthy + MotC + Green Blossom + GCS = CONSTANT STAMINA
Should be able to chase people fairly well with this build. With the armor setup I have on the build, you can use any weapon that is allowed under 16/14/8/10, so long as it's under 7.7 weight. You could adjust the armor so that you can use the heavier 16/14 weapons (like the 2H Zweihänder), just remember that 31 Poise is a very good point to shoot for.
Of course, don't use +15 weapons on this build. Elemental ones will give you more damage, generally speaking. Fast-rolling is also very important to this build, as there's a major emphasis on constantly using up your stamina bar to make all of the regen worth it. Should you find it unnecessarily high, consider using the DWGR instead of the Cloranthy Ring.
