Planejammer Campaign Setting
|Material||Hardness||HP/Inch||Break DC||Weight (% of Steel)|
|Ablative polymer (1)||40||30||+ 9||75%|
|Crystal carbon||15||35||+ 4||80%|
|Deflective Polymer||40/20 (2)||25||+ 6||80%|
|Neutronite (nanofluidic)||50||60||+ 10||450%|
1. Ablative polymer gains part of its hardness from its ability to increase its strength temporarily by shedding some of its mass. Any object made of this silvery material must be given constant minor repairs or it begins to degrade. Each time it does not receive regular monthly maintenance (purchase DC 1/10th the object’s full cost), its hardness drops by 2, until it eventually falls apart entirely (at hardness 0). Such repairs are part of regular starship maintenance, and thus the material has no additional cost when used in starship construction.
2. The hardness of a deflective polymer is 40 against energy attacks, but only 20 against all other damage.
The hit points given in the table above are per inch of thickness. Many of these materials are specifically designed to give good protection with only a thin layer. Thus, a 12-inch thick steel vault door could be replaced with a vanadium door only 6 inches thick.
The break DCs are given as modifiers for easier use. When a manufactured object is made of a material from the table rather than normal steel, its normal break DC is modified by the indicated value. Thus, a pair of heavy-duty handcuffs made of starship plating alloy has a break DC of 35 instead of the normal 30 for steel. This modifier also represents the increase in an object’s purchase DC when made of the indicated material. Neutronite bolt cutters, therefore, would have a purchase DC of 14 instead of 6.
The weight values in the table are given as a percentage of the weight of a comparable object made primarily of steel (the default for most metal weapons, armor and gear). Thus, bolt cutters made of neutronite weigh 25 pounds instead of 5 pounds.
