Fire elementals are terrible to behold and fierce opponents.
They set fire to any inflammable material they touch.

Against fire-using opponents they score -1 on their damage dice.

Fire elementals are checked by water, being unable to pass over non-inflammable liquids.

On the elemental plane of fire exist many sorts of different fire elementals
and similar beings. The ruler of all fire elementals is reported to be known
as the tyrant.

(see also Efreeti, Salamander)

At that time elementals were rubbery dime store critters about 65 mm scale, each vaguely reminiscent of the element it represented, the fire figure a red and orange, the water one shades of blue, Can't recall the color of the air one, but it was whirrled I think. The earth elemental figurine was sort of man-like and lumpy perhaps. Memory begins to fail me after some 35 years.

Cheers,

    The Elementals: Creatures made of elemental fire have a
wispy substance and appear to be constructed of fiery shapes of
various volumes, forms, and destinies. A single creature (such as
the flame roper from the chart above) can differ in appearance
from one time to another, from a white-hot beast resembling a
tree to a dull-red spiral-shaped creature with radiating spikes of
blue flame, for example. In both cases, the creatures has the abilities
of the roper known to natives of the PMP.
Appendix II on page 120 gives notes to help the DM determine
the appearance of inner planar monsters.

    Creatures of pure elemental fire prefer the hot banks where
there are few elemental pockets. Their favorite hang-outs are the
super-heated hot spots, which exert a healing influence upon
them. They avoid the cold spots and the intrusions of such rare
substances as elemental water and para-elemental ice.

    These creatures are generally hostile to Prime Material beings,
which they perceive as little more than walking water bottles looking
for an accident to burst. Those of low INT or higher
can be recruited as elemental guides in return for rare or interesting
combustible material. Creatures of elemental fire burn and consume
this material for variety, much like those on the Prime Material
USE perfume or cologne.
