A: The spell acts like a selective translator.
The caster picks one creature within the
area of effect. Then he speaks to that
creature in any language that he knows;
the target creature magically understands
what is said. Any creature who understands
the language that the caster is using
can understand what the caster says if it
can hear him. No creature who does not
understand the language that the caster is
using can understand what the caster says
?except the target creature.
The reverse holds true when the creature
replies. It uses a language that it
knows. The caster, and any other creature
within earshot who speaks the language
that the creature is using, can understand
what the creature says.
The caster can freely shift the spell?s
target from one creature to another for as
long as the spell lasts.
