Rust monsters inhabit only dark subterranean places. They roam such
places in search of their food -- metals of all sorts, but principally ferrous
based metals such as iron, steel, and steel alloys (such as mithral and
adamantite arms and armor).

Destroy Metal: If the rust monster touches the metal with its two antennae (roll ”to hit” die) it rusts or corrodes the metal.
Note that magically endowed items gain a saving throw, a 10% chance of not being
affected for each plus, i.e. a +2 weapon or armor gains a 20% chance of
being saved. Metal affected rusts or corrodes and immediately falls to
pieces (which are easily eaten and digested by the creature).

Hit On Monster Destroys Metal: Weapons striking a rust monster are affected just as if the creature’s antennae had touched them.

Rust monsters can smell metal at 9” distance. They will stop
for a melee round to devour such items as a handful of iron spikes or a
mace if a fleeing party throws them away, but they will go after ferrous
metal in preference to copper, silver, etc.

ADQ: Why must a rust monster hit a
victim's normal AC? Magickal
plate <mail> +4 would
seem to be as easy to hit as
non-magickal armor -- and both far easier
than penetrating that armor to inflict
damage.
ADA: Come On -- rust monsters are nasty
enough already. If you insist on being logical
about it, and use a base of AC 10 modified
only by magick and DEX, then
continue the logic to cover the situation. If a
hit is scored, check to see if Metal was hit,
or merely leather or Something Else. This
might be a 70% chance for plate mail, less
for other types. Then if Metal was hit,
check to see if it was the armor, or merely a
fitting, a gauntlet, a boot, shield, etc. <define fitting>
    Note the DRAGON magazine
article on the ecology of the rust monster
offered a plausible but not official rationale
of its attack mode.
    The AD&D Game uses the abstract "to
hit" roll for maximum playability without
extreme unrealism. Game modifications for
more "realism" (in a fantasy Game?) usu.
add More complexity and result in
slower play. If that's what you want, go
ahead -- but be sure to consider all the
aftereffects of each change before implementing
it.

Q. What happens to cursed armour
and/or weaponry when hit in combat
by a rust monster or disenchanter?
A. We suggest that when any cursed
metal magick item is hit by a rust
monster it should be treated like any
other magick item attacked in this
fashion.  The cursed object will have a
10% chance that it will not rust per
'minus' of the object.  A rust monster
is not interested in the magickal
nature of the metal object, merely its
food value as rust.
    We think the disenchanter will probably
have a disinclination for draining
the magick from a cursed item.  It lives
on the energy inherent in magick
items, and the energy in cursed items
might be expected to come well down
on its gourmet preference list.  But
Don Turnbull thinks otherwise, and
he wrote the thing. Take your pick.
<Roger Musson is listed as the creator of the disenchanter!>

The original rust monsters ....


 
 


Heh...

As near as I can recall the rust monster was brought into action first on the sand table in my basement at 330 Center Street back in early 1973.

The rust monster always had to be one of the most feared creatures in my game.
Mainly for the embarrassment factor. One can beat up, abuse, harass, damage and otherwise do all manor of unpleasant things to a character, and they would sit and take it.

But dissolving their nice shiny plate armor was always something these same characters would crawl over broken glass to avoid. Especially otherwise dignified paladin types. 
 


Yes indeed!

Cheers,

AFAIK the monster figures were imaginary creatures...e,g. the ones we named bulette, owl bear and rust monster.

Cheerio,
Gary

That is so, but the name and stats were created by Tim Kask, then editor of Dragon Magazine.

Pish!

The scrap from iron battleships would feed all the Oerth's rust monsters for a century, that without considering automobile junkyards <devious>

Heh,

As if the iron ore fouind on Oerth is less than that found here....
