Animal Noise (1, WIS, -1): A character with this proficiency is capable of
imitating noises made by various animals. A successful Proficiency Check means
means that only magical means can distinguish the
noise from that of the actual animal being imitated. A failed die
roll means that the sound varies from the correct noise in some
slight way.

If the die roll fails, this does not mean that all creatures hearing
the noise know that the sound was fake. While creatures and
humanoids that are very familiar with the noise know this automatically,
other creatures or characters in earshot are allowed
WIS Checks to determine if they detect the fake.
