All armors within the game of Planet Mercenary sport some degree of Damage Reduction, which reduces incoming damage.
Damage Reduction: Each time you suﬀer damage while wearing the armor, reduce the damage by this amount. Some attacks may have the ability to ignore Damage Reduction.
Some armor also has Hull Points
Some of the heaviest armor also provides you with 1 Hull Point (Hull) of protection. This is equivalent to the lightest raw protection on a space vessel, and it blocks all physical damage until an enemy frst punches through that layer (some exceptions exist to this rule, as noted for various attacks). An attack that inﬂicts any amount of hull damage destroys a suit of armor, including one oﬀering one or more Hull Points of protection. In a suit of armor oﬀering hull protection you can withstand a single attack that inﬂicts hull damage, but afer that the armor is destroyed and you’re eﬀectively not wearing armor at all.
This armor also has Damage Reduction, despite that any weapon that doesn't do Hull damage doesn't do any damage and a weapon that does Hull damage totally destroys the armor. So, where does the DR come in?
