Otto's Soothing Vibrations (Enchantment/Charm)

Level: 2
Range: 60 yds
Duration: 1 round/level
Components: V
Casting Time: 2 rounds
Saving Throw: Special
Area of Effect: 20'-radius sphere

As the mage casts the spell,
all creatures in the area of effect begin to hear soothing
vibrations that cause them to pause and listen. As the
music continues, the creatures feel the mage broadcasting
peaceful, kindly thoughts to them. The creatures will do
nothing for one round until the mage is finished casting
the spell. Thereafter, all animals in the area of effect of
semi-intelligence or lower will feel kindly to the mage, and
show no aggression or fear unless attacked first. All other
creatures are entitled to a saving throw at +2 to avoid the
spell’s lulling effect. All animals and those creatures who
fail the save are more susceptible to charm spells cast
before the spell’s duration ends, and suffer a -2 penalty
against any charm spell cast upon them, such as animal
friendship, charm person or mammal, or charm monster:
There is no somatic or material component to the spell, just
the soothing, vibrating voice of the caster.
