Special Abilities

• Iron Scent: The rust monster can pinpoint, by scent, the location of ferrous metal within 30 feet of it.
• Monstrosity Resilience: The rust monster is resistant to exhaustion and to the frightened condition.
• Rust Metal: Any nonmagical weapon made of metal that hits the rust monster corrodes. After dealing damage, the weapon takes a permanent and cumulative -1 penalty to damage rolls. If its penalty drops to -5, the weapon is destroyed. Nonmagical ammunition made of metal that hits the rust monster is destroyed after dealing damage.

Actions

• Bite: Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 8 (2d6+1) piercing damage.
• Antennae: The rust monster corrodes a nonmagical ferrous metal object it can see within 5 feet of it. If the object isn't being worn or carried, the touch destroys a 1-foot cube of it. If the object is being worn or carried by a creature, the creature can make a DC 11 DEX save to avoid the rust monster's touch.
  If the object touched is either metal armor or a metal shield being worn or carried, it takes a permanent and cumulative -1 penalty to the AC it offers. Armor reduced to an AC of 10 or a shield that drops to a +0 bonus is destroyed. If the object touched is a held metal weapon, it rusts as described in the Rust Metal trait.

Bonus Actions
