FArmorRatingMax

This decimal value is used to determine the maximum armor contribution of all equipped items and effects. The default is 85.00, it is currently unknown how armor reduces damage and the benifit of having a fraction of a point. Every piece of armor contributes it's armor value directly to this value. Every % of shield and fire/shock/frost shield also adds 1 armor. It could be that armor is a simple damage reduction percentage.

(Note by Lobo: There are two very similar looking, but different, settings, FMaxArmorRating, which sets the maximum percentage of damage that can be blocked by armor, and which defaults to 85, and FArmorRatingMax (this setting), which has a value of 1, and has an effect as yet unknown to me)
