The technique is known as dragon skin, this helps the athlete of Faal Baas do Thiik Faak to have a skin of iron. Constant practice has toughened your skin and makes your strikes almost as hard as a rock.
Prerequisites: Dragonborn, Con 15, Dex 15, Improved Unarmed Fist, Baas do Thiik Faak style, base attack bonus +11 or Monk level 9th.
Benefit: While using this style, you gain a +2 tough bonus to your AC; plus you also gain +2 to damage with your strikes on your opponent. This technique does not protect you from attacks of opportunity. If you change to another style, the benefits do not last.
