Duration:  Special
Components: V, S, M
Casting Time:  3 turns
Saving Throw: None
Area of Effect:  Special

This spell summons a faithful
phantom being to watch over and protect the mage for
one day. The guardian will remain an undetectable observer,
watching the caster from the ethereal plane. The guardian
can see what is happening within 60 feet of the caster,
and can spot invisible, out-of-phase, duo-dimensional, ethereal,
or astral creatures within the area around the mage.
If the guardian spies any creature about to launch a surprise
attack on the caster, the guardian will instantly
materialize to intercept the attacker and defend the mage.
The faithful phantom guardian: AC 2; Move 15” ; HD 6; hp
36; #AT 1; Dmg 1d10 (two-handed sword); THACO 13; AL
N; SA able to hit creatures which are hit only by +2 magi-
cal weapons. The guardian will fight for up to one round

per level of the caster or until it is destroyed. The mage also
has the option of summoning the guardian to his side at
any time. The guardian will appear in one round and fight
under the same time limit. Once the guardian has spent its
time on the prime material plane, it has completed its mission
and will no longer watch over the caster.
The guardian appears as a shimmering outline of violet
light. The phantom guardian cannot speak, so it cannot
shout a warning to the mage if he or she is attacked. 

MC: A 1,000 g.p. diamond, which is sent

to the guardian when the spell is cast as a payment for its
service.
