Actions

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 1d10+2 piercing damage.   Antennae. The tarnished terror corrodes a magical or 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 must make a DC 14 Dexterity saving throw to avoid the tarnished terror'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. The tarnished terror may use this ability up to four times in a single turn.

Suggested Environments

Generally found in the depths of mountain ranges and anywhere rust monsters can usually be found.
