Sacred 2:Opponent's armor: Physical
Directly reduces the amount of physical armour (resistance) of the targetted enemy by a percentage. Applies only to weapon damage. This effect has a duration of 30 seconds. This is long Debuff.
Only one Opponent's armor: Physical -X% effect can be active on a monster at a time. The next time it is triggered, it will reset the timer.
