For many adventurers, the sight of a Rust Monster is enough to cause them to turn and flee in terror for their metal goods, yet for the Kobolds of the New Lands it’s a sought after beast! With so many metalic beasts stalking the landscape, equipment fashioned from its carapace, mandibles and squishy innards are invaluable!
The Monstrous tag applies to any weapon, item or material garnered uniquely from a creature, whether it be the eye of a Black Dragon, carapace of a Rust Bug or pelt of a Displacer Beast.
Rust items are inherently Monstrous, being made largely from the parts of the common Rust Monster
When using an item, deflecting damage or using Hack & Slash on a 10+, apply a stacking -1 to the targets weapon damage or armor rating, as is appropriate to the action causing contact (E.G A shield with the Rust tag deflecting an attack applies -1 damage to the enemies weapon) so long as the offending object is made largely of metal (Platemail, Chainmail, Swords etc).
Items with the Rust tag may not contain ANY metal in them and as such are considerably heavier, using materials like stone and and excess of wood where metal may save on weight. Weapons with the Rust tag generally have lower damage to their metal counterparts, being difficult to sharpen and soon loosing their edge!
