  • In damage calculation, the base damage will combine armor effective defense, hit body part to calculate the random factor in the hit, which will reduce armor effects. The purpose is to simulate armor thickness distribution.
  • Although vanilla armor only provided 4 part of defense, the random factor entend it to 7 body part . For now, it's not configurable
