As soon as you enter Fire Shrine take bones under lift and then make a death run to grab Great Club in Blighttown(Bone out or die). Then eat enough souls and put it into Str so you can 2-hand it(19 str).
Proceed the game anyway you like :)
But put on FaP ring, Giant's Armor and Father's Mask as soon as possible.
Your leveling way is (in order) :
-Vitality up to 25 (That's enough)
-Endurance up to 43
-Always Strength every next point
The point of the build is that you can use the best armor and hardest hitting weapon while also doing mid roll and have a FLEX ring(without Havel's).
So you can use Cloranthy/Abyss/Anti-Lava/Silver/Golden Serpent any time it's appropriate. But feel free to use Havel's ring with any armor before getting Giant's Armor and Mask.
