Metal objects and items are destroyed. Magical or attended metal objects are entitled to a DC 23 Reflex save. If they succeed, they instead gain the broken condition. Broken metal objects in the area of effect (attended or otherwise) are automatically destroyed. ### Metal Resistance (Ex) A rust dragon's damage reduction is stronger against any weapon that has a metal damage-dealing end (arrows, blades, mace heads and the like). ### Powerful Jaws (Ex) A rust dragon can bite through even the most durable material. When a rust dragon bites into an object, its treats that object's hardness as 1 less than normal per age category. ### Rusting Bite (Ex) A juvenile or older rust dragon that makes a successful bite attack causes metal armor worn by the target creature to corrode, falling to pieces and destroying the item. A dragon can also use its bite attack to target a weapon or other metal object, of course. Magic metal items are allowed a DC 23 Reflex saves to avoid the effect. #### Ecology **Environment:** Any (Acheron) **Organization** Solitary (1 dragon, any age), clutch (1d4+1 wyrmlings, very young, young, or juveniles or young adults), family (pair of mature adults and 1d4+1 offspring) **Treasure** Triple **Advancement** By age category Native to the Infernal Battlefield of Acheron, rust dragons are creatures of tarnished metal, embodying forces of decay and corruption. Some Material Plane sages posit some connection between these fiendish monstrosities and the relatively innocuous rust monster, but the rational mind correctly sees these claims as the ravings of deranged lunatics. Rust dragons bear a strong resemblance to the metallic dragons of the Material Plane, but appear covered in rust, tarnish, or verdigris. Though some rust dragons resemble copper dragons and others silver or brass, individual rust dragons’ abilities do not differ. Their scales appear pitted and lined with corrosive color, and the membranes of their wings are very thin and iridescent. On their native plane of Acheron, rust dragons have an ample food supply in the endless iron cubes the size of continents floating in the void. When drawn to the Material Plane, rust dragons seek out veins of metal in underground caverns, making them particularly loathed by miners. Rust dragons feed on corroded metal, but enjoy fresh meat (particularly vermin) to cleanse the palate between ores. ### Combat Rust dragons are not the furious forces of nature that pyroclastic dragons are, nor are they violently insane like howling dragons. Rather, they are simply hungry, and they attack carefully with their goal clearly fixed in mind. They do not tolerate too much interference in pursuit of that goal, and readily break off from combat if a meal proves to be more trouble than it’s worth.
