Rust devil

Useful Info

Rust devils are tier-4 demons with multiple resistances and moderately powerful physical attacks. Although less intimidating than most demons, their real strength lies in the fact that their attacks apply corrosion, significantly hampering your effectiveness with weapons and weakening your armor. They can be commonly found in the Vestibule of Hell and Pandemonium, and rarely in earlier parts of the game.

Tips & Tricks

• Corrosion resistance will halve the amount of corrosion stacks they afflict.
• If you find one early, they have decent AC and EV for their tier, so use attacks that will punch through their armor. Just be aware they are totally immune to fire, and resist cold and electricity damage.
  • If you find them later in the game, they are weak enough that most well-prepared characters will be able to take them out before they can land a corroding hit. Just be wary of letting them engage you while you're distracted with another foe; Pandemonium is not the sort of place where you want to be heavily corroded.
  • They are not themselves resistant to acid damage or corrosion, making a wand of acid a great choice for dealing with them.
• Their attacks do not apply any extra acid damage.
