Creatures other than rust monsters that affect metal?

[cowsay]

Are there creatures other than rust monsters that affect, damage, rust, weaken metal?

Are their creatures that are cousins to rust monsters that affect other types of materials?

I would love to know about these creatures, what they can do, and where I can find them (i.e., in what source).

Oozes have acid that in some cases can affect metal.

Cool. I'll check them out. Are there any in particular that you like?

I think there is a rust dragon somewhere as well.

Draconomicon. It's actually quite nasty; with really high DR against metal weapons, an alternate breath weapon that can dissolve any metal, and a capstone ability that corrodes any weapon less than +5 without it doing any damage and forces +5 or more to make a reflex save or rust away.

It's pretty damned nasty. But an excellent surprise for a DM when the party is gearing for a fight with a "mere" rust monster.

There's the Annihilator, the steroid-boosted rust monster in Underdark that disintegrates instead of rusts.

These are great. I'm obliged and welcoming more suggestions. That gem one is really interesting.

What about sundering, especially the age-old "I'm going to sunder your BoH and totally ruin your WBL for the next 8 games" strategy?
And doesn't Vow of Peace give you a quality that shatters weapons that strike you?

I don't know if this counts, but the Steel Predator from Fiend Folio can do some nasty things to metal. :smallbiggrin:

GREEN SLIME. Kind of like oozes, but cooler, cause it counts as a plant. Which means that it's a druid's best friend. I think the only thing it doesn't eat through is stone. I believe the only source for it is the depressingly sparse DMG entry under the traps and hazards section.
