I made this fist build for my fist only play-through of Dark Souls 1. Gauntlets of Thorns give an additional 10% fist dmg so they are a must. Power within is for killing bosses and the weapon buffs are just to do dmg while fighting through the level. You can switch out the DWGR for any ring you think would fit. I switch it out with the Hornet Ring if needed.
Overall it's really challenging but fun 10/10! I am going to make a Dark Souls 2 fist only build next!
