The alu-demons are the offspring of the mating of succubi and humans.
They are always .
Their base AC is high because of their demonic heritage,
and this can be increased by magical protections,
including enchanted armor.
Wearing only mundane protetction interferes with intrinsic protection of alu-demons,
so this is never done.
If the protection is basically inferior to the normal armor class <AC> of the wearer,
then only the magical plus <(+)> is added,
but otherwise full benefit is gained.
    Thus, +1 leather adds +1 only,
    while +1 plate mail would increase AC to 2.

Furthermore,
alu-demons with high dexterity gain bonuses as would a normal human.
<25%> of alu-demons are of genius level.
While most of these creatures are able to perform the limited number of spell-like powers listed below,
those of genius intelligence are actual magic-users.
Magic use level ranges from 1st through 12th level with equal probabilities for each.
<1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th>
Magic use is in addition to intrinsic powers.

The intrinsic powers of alu-demons, performable 1 at a time, 1 per round, are :

    charm person,
    ESP,
    shape change (to a humanoid form of approximately their own height and weight only),
    and suggestion.

Each can be performed up to 3 times per day,
at the 12th level of ability.

    dimension door can be used once per day.

All alu-demons have superior infravision for 240 feet.

In addition to the ability to employ any sort of weapon,
regardless of normal class restrictions,
alu-demons can,
at will,
drain life energy from a person and use half of it to restore their own lost HP.
Such attacks must be by firm touch,
indicated by a successful to-hit score in melee.
From 1-8 HP of energy are drained.
Energy gained is from 1-4 HP,
with fractions rounded up.

Alu-demons can be harmed only by cold-wrought iron or magic weapons.
They have natural resistance to magic.
Some 20% are not totally devoted to Evil.
<marry me>

Alu-demons appear quite human, having only vestigal horns.
Only their rather small bat wings betray them for what they actually are.

Q: Both the succubus and the alu-demon
have the ability to shape
change into humanoid creatures of
roughly their own sizes. Is this a
true shape change ability, in that
these monsters actually gain the
abilities of their new forms? Also,
how great a change in size is
allowed?

A: These creatures? shape change abilities
are not the same as the ninth-level magicuser
spell; they are similar to the more
limited druidic ability. The ability is only
useful for disguise and deception, to conceal
these creatures' demonic natures.
These demons are limited to the forms of
creatures that are identified as "persons"
on page 45 of the Players Handbook and
similar creatures from the FIEND FOLIO®
tome and Monster Manual II. The disguise
is complete, however, and the demon
receives all of the racial abilities of the
new form. For example, a succubus shape
changed into a dwarf would be able to
spot unsafe stonework, determine depth,
etc. Remember that character levels are
not a racial characteristic. I suggest limiting
the change in size to 25% of the original
creature?s actual height and weight.
