Note: This information was taken from TSR's original AD&D adventure, the Temple of Elemental Evil.
For the players: The walls of this 20' x 40' room are
frescoed. Two suits of plate armor hang
from each long wall, north and south;
each is of black metal, enameled with
strange glyphs in pigments of red, white,
green, and brown, surrounding a golden
skull. The armor is strangely fluted and
spiked; the helmets are wrought to give
the wearer a most frightening appearance.
Each of the four suits of armor also
bears a huge two-handed sword.
For the DM: These four suits of animated armor guard
this room, attacking all those who enter.
They are immune to all magic, but can be
struck by any sort of weapon. They fight
mindlessly, until destroyed, to prevent
intruders from remaining in or passing
through the chamber. They will not enter
area 344, but will pursue intruders down the
west passageway and all other rooms (areas
346-353) except 340. The golden skull inlaid
on each suit of armor is actual gold, worth
50 gp. Four topaz gems are also inset in each
suit (each gem worth 500 gp).
Suits of Armor (4): AC 3, MV 6", HD 9,
hp 45 each, #AT 1, D 1-10 (two-handed sword),
SD immune to all magic, damaged only by blows (any weapons);
XP 2140 each (x4)
For the players: The frescoes show crowned and robed
humans, attended by demons of minor
sorts, and slaves bearing rich rewards
parading in triumph before a horrible
bloated figure upon a throne-like seat. The
mottled fungous body-sphere of this creature
is topped by a toadstool-like growth
with a face upon it. The body has four elephantine
legs, but no visible arms. Seated
beside this abomination is an obese male
demonic figure (a cambion, in all probability),
also seated on a throne.
