Notes from author
Dex/Faith build with Power Within. Greatshield Of Artorias (GoA) may be swapped for Grass Crest Shield (GCS). While using GCS, I suggest 2-handing the Great scythe or other large weapon of choice. Defeat Gwyndolin on NG, then join Darkmoon Covenant on NG+, Farming souvenirs of reprisals (SOR) offline (Farm crow-women in Ariamis) or online. Once offered 10 SORs to Gwyndolin, recieve Darkmoon Catalyst and Darkmoon Blade. GoA may also be swapped for Sanctus to negate or reduce the life drain effect of Power Within. Armors maybe swapped around for lighter equipment. I suggest:
Thief Mask
Wanderer's Coat
Tattered Manchette???
Blood-Stained Skirt
Either use that for light or fully upgraded Black-Iron set as heavy set. If using a bow, I suggest using the Black Bow of Pharis for range, or Darkmoon Bow for damage. If not speedrunning for Great Scythe (GS) at the start, I suggest using the Drake Sword, hence the reason I threw points into strength. If not using Drake Sword at all, throw all points of strength into Dexterity because of the A rating on a fully upgraded GS.
If you do not have the darkmoon talisman and/or have low faith, I suggest using Thorolund talisman with low faith, or Ivory/Default Talisman.
You may want to switch out Great Heal for another Sunlight/Darkmoon Blade or another miracle/pyromancy spell. I did not bother upgrading Power Within, as I believe it has no effect on Power Within if you have a stronger Pyromancy Flame, does it not?
