Entropic Alloy

Entropic alloy is a mixture of dense metals native to the Negative Energy Plane, harvested from the core of the drifting islands of stone that break from the plane’s outer rim. The last thing to decay as the Void consumes all matter, this alloy is exceptionally resilient to the plane’s entropic energies, making it the ideal material for armor and environmental suits that withstand the hazards of planar exploration. Given the limited amount that can be harvested and the difficulty involved in acquiring it, plating a starship with entropic alloy is prohibitively expensive. The metal is cold to the touch, but pockets of heat pulsate across its surface in a weak rhythm distressingly similar to the beating of an organic heart.
Entropic alloy weapons and ammunition that deal cold damage, whether inherently or from a weapon fusion, ignore cold resistance of 10 or less. Armor made from entropic alloy grants the wearer cold resistance 5, a +1 to saving throws against hazards that deal cold damage, and ignores cold damage dealt by the environment of the Negative Energy Plane.
