An Idea I had for Armor in the Game is to change the Order Armor Damage Multipliers and Flat damage reduction, so the Damage Reduction would be applied before the Damage multipliers.
Im still fairly new to edit Rulesets of Openxcom (Im playing with the Final Mod Pack if that plays into the Topic), but I know how to change values of existing Items and add new values to them, but I dont know if it is possible to change the way the Game calculates Armor damage reduction, and if it even is how to change it
