|action2=Antennae
|alimit2=
|adesc2=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 {{SRD5|DC}} 11 {{SRD5|Dexterity}} {{srd5lc|Saving Throw}} to avoid the rust monster's touch.

If the object touched is either metal armor or a metal shield being worn or carried, its takes a permanent and cumulative −1 penalty to the {{SRD5|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.
