===Weapons===
One weapon is obvious – Natalya’s Mark. Good consistent damage, huge attack speed, enhanced damage to demons and undead, and most importantly, ignore target’s defense. The other claw is also a pretty obvious choice for this build. Bartuc’s Cut-Throat is great for its good damage, huge bonuses to skill levels (2 to all and an additional 1 to Martial Arts), faster hit recovery, life steal, and huge bonuses to strength and dexterity. Combined with Natalya’s Totem, I only had to boost my strength to 109 to wear Natalya’s Shadow (strength requirement of 149). This allowed me to drop those 40 stat points into vitality. I also stuck an Amn rune into my Bartuc’s to boost my life steal up to 16% per hit. I think that you may be able to get by with other claws such as Firelizard’s or Jade Talon, but Bartuc’s is absolutely ideal for the strength boost and skills.
