Traits

Rusting Defense

Whenever an attack using a metal weapon hits the rust monster, the weapon used in the attack is rusting until the end of the encounter. While the weapon is rusting, attacks with the weapon take a -1 penalty to attack rolls. If the weapon used to attack the rust monster is already rusting, the penalty to attack rolls worsens by 1 (to a maximum penalty of -5).

Standard Actions

Bite At-Will

Attack: Melee 1 (one creature); +13 vs. AC

Hit: 3d10 + 3 damage. If the target is wearing heavy armor, the armor is rusting until the end of the encounter. While the armor is rusting, the target takes a -1 penalty to AC. If the target is wearing armor that is already rusting, increase the penalty to AC by 1 (to a maximum penalty of -5).

Devour Metal Recharge if the power misses

Attack: Melee 1 (one creature wearing or wielding a rusting item); +11 vs. Reflex

Hit: The rusting item is destroyed. If the item was magic, residuum worth the item’s market value can be retrieved from the rust monster after the creature is slain.

Gluttonous Bite Encounter

Attack: Melee 1 (one creature); +13 vs. AC

Hit: 4d10 + 8 damage. If the target is wearing heavy armor, the armor is rusting until the end of the encounter. While the armor is rusting, the target takes a -1 penalty to AC. If the target is wearing armor that is already rusting, the penalty to AC worsens by 1 (to a maximum penalty of -5). In addition, any weapon the target is wielding is rusting until the end of the encounter. While the weapon is rusting, attacks with the weapon take a -1 penalty to attack rolls. If the weapon is already rusting, the penalty to attack rolls worsens by 1 (to a maximum penalty of -5).
