Effect: The shadow monsters spell enables the illusionist to create semi-real phantasms of one or more monsters.

The total HD of the shadow monster or monsters thus created cannot exceed the level of experience of the illusionist;
thus a 10th level illusionist can create one creature which has 10 HD (in normal circumstances),
two which have 5 hit dice (normally), etc.
All shadow monsters created by one spell must be of the same sort, i.e. hobgoblins, orcs, spectres, etc.
They have 20% of the hit points they would normally have.
To determine this, roll the appropriate hit dice and multiply by 20, any score less than .4 is dropped
-- in the case of monsters with one (or fewer) hit dice,
this indicates the monster was not successfully created --
and scores of .4 or greater are rounded up to one hit point.

Saving Throw: If the creature or creatures viewing the shadow monsters fail their saving throw and believe the illusion,
the shadow monsters perform as normal with respect to armor class and attack forms.
If the viewer or viewers make their saves, the shadow monsters are AC 10 and do only 20% of normal melee damage (biting, clawing, weapon, etc.), dropping fractional damage less than .4 as done with HP.

Example: A shadow monster dragonne attacks a person knowing it is only quasi-real.
The monster strikes with 2 claw attacks and 1 bite, hitting as a 9 die monster.
All 3 attacks hit, and the normal damage dice are rolled: d8 scored 5, d8 scores 8, 3d6 scores 11 and
each total is multiplied by .2 (.2 X 5 = 1, .2 X 8 = 1.6 = 2, .2 X 11 = 2.2 = 2) and
5 hit points of real damage are scored upon the victim.

ADQ: Can an illusionist create a creature
with a gaze attack from the
Shadow Monsters spell? Will the gaze
attack work since the monsters created
by the spell are in part real?
ADA: The gaze attack is real some of the
time. Use the percentage of normal damage
potential given by the spell description
(i.e. 20% for Shadow Monsters,
40% for Demi-Shadow Monsters,
60% for Shades) as the chance that the
effects of the gaze attack will be real.
Check each time the gaze is used. Victims
are still entitled to the appropriate save.
