Special Attacks

Rust. If the rust monster’s antennae touch metal (determined by a successful attack roll), the metal rusts. Magical items have a chance of being unaffected equal to 10% for each plus (a +2 weapon or armor has a 20% chance of not being affected). Any affected metal rusts or corrodes and immediately falls to pieces that are easily eaten and digested by the creature. Metal weapons striking a rust monster are affected just as if the creature’s antennae had touched them.
