It's hard to make a decent lifehunt build for sl100 But I think this hits the mark.
Pros
-31 poise breakpoint
-Good bleed res/bloodbite
-Fast roll
-Appealing look
-45dex for high scythe damage/fast pyros
Cons
-Doesn't hit the higher poise breaks
-No stam regen from equip
-Crappy blocking
You can swap in a greatscythe instead if you want, or if you don't feel bloodbite is needed. Either way frees up a ring slot you can use on FAP or Cloranthy.
