Thought eaters are dwellers in the ether. Their senses, however, extend
into the physical plane, and any psionic or psionic-related energy use in
either AREA will attract their attention (range of ability or magic equals
attraction range). The thought eater appears to be something like a sickly
gray, skeletal-bodied, enormous headed platypus to those who are able to
observe it. Its webbed paws allow it to swim through the ether. It can be
attacked only by ethereal creatures.

Its only desire is to feed on the mental
energy of prey it is attracted to, and if it comes within 6" of any creature in
the ethereal or physical planes it will be able to absorb any psionic or spell
energy they attempt to use; at a range of 1" the thought eater is able to
begin feeding on the actual thoughts of even non-psionic creatures. Each
thought eater is able to consume from 101-200 psionic energy points
before becoming sated. Convert magical energy to psionic points on a
basis of 5 points per spell level, and actual thought consumption converts
to 1 INT point equalling 10 psionic energy points. Note that if it
feeds on thoughts the creature loses intelligence permanently. At
intelligence 0 the creature is dead, 1 equals mindlessness, 2 idiocy, 3 <what about creatures with a 0 INT?>
imbecility, and an intelligence of 4 is equivalent to a low-grade moron.
Mental defenses, including a mind blank spell, and magical devices
against psionic and psionic related powers thwart attacks of these horrid
things.
