I am not familier with the calculations on the amount of damage returned when using any item or armor that has the "reflect physical damage" modifier,so I just assumed that the math on it was pretty straight forward. IE if you have a suit that has 50% reflect physical and take 50 damage from a hit,25 is returned back to the attacker. Is this not correct? Or does the physical resist of the attacker come into play? I have the Aegis shield equiped as you can see,and no other armor that provides that mod. I have never been great in math but,15% of 27 damage is not 1.
