Effect: A yawn cantrip makes the subject creature feel a brief wave of drowsiness which in turn evokes a yawn reaction.

If a save vs. spell succeeds, the subject creature is totally unaffected by
the dweomer of the cantrip. Failure, however, not only forces a yawn to
immediately occur, but the subject is then more susceptible to a sleep spell.
During the balance of the round in which the yawn cantrip was
cast, and during the whole of the following round, the subject will
automatically fall into comatose slumber from a sleep spell cast upon it,
so 1 additional creature will be vulnerable to the spell if more than 1
creature of 4 or fewer HD are subjected to the spell. Further, if
creatures of 4+1 to 4+4 HD are involved, there is then a chance
that two such creatures will actually be affected by sleep. Even a creature
of up to 5+2 HD can be affected by the sleep if previously victimized
by a yawn cantrip, but the effect of the sleep spell is rolled for as if
the creature had 4+1 to 4+4 HD; i.e., there is a 50% chance that
it will not be affected.
