Innate, Defense
Cost: 2 XP/tier
Prerequisites: Constitution or Strength
You gain a +[Tier] innate bonus to you Armor Rating (natural armor bonus to AC).
Heavy Armor (0 XP): Choose an existing armor made of bone, chitin, hide, leather, or scales. You gain this armor as innate armor and can never take it off or benefit from wearing armor over it, including its max dex, check penalties, etc. You can sleep comfortably in your own innate armor. Unlike the normal armor, it provides you an innate bonus to Armor Rating (Armor Class) rather than an item (armor) bonus. Half your tier in this ability (rounded up) increases the innate armor bonus provided. Half your tier in this ability rounded up is an enhancement bonus to your innate armor and doesn't stack with other enhancements.
