Bismakeech is just a placeholder for the name:


Fey (Bismakeech, Shapechanger)
Medium
Speed 30ft.
CN
+2 Cha, -2 Wis (+2 Str, Dex or Con while shapechanged)
Low-light Vision
+2 Racial Bonus to Bluff and Disguise


Change Shape (Su, 5 RP): A bismakeech can assume the appearance of a specific single Medium humanoid. The bismakeech always takes this specific form when it uses this ability. The bismakeech gains a +10 racial bonus on Disguise checks to appear as that type of humanoid. In humanoid form, a bismakeech gains a +2 racial bonus to either Strength, Dexterity, or Constitution. While in this form, a bismakeech also takes on racial features that provides a special effect. Each time a bismakeech assumes humanoid form, she can choose to gain one of the following features:

>Darkvision
>Small size
>+1 Natural Armor

These benefits last until the bismakeech returns to her true form as a swift action. A bismakeech must first return to her true form before changing to humanoid form again to change benefits. A bismmakeech can select a new humanoid form by spending 1 week preparing itself for the change, but can then no longer assume its previous humanoid form.

Shattered Soul: Bismakeech who are killed are exceptionally difficult to return to life. Those who attempt to return a bismakeech to life using raise dead, resurrection, or similar spells must succeed at a caster level check equal to 10 + the bismakeech's Hit Dice. If this check fails, the spell fails and the caster can't return the bismakeech to life for the next 24 hours (though the caster can try again after this period).

Sound Mimicry (Ex): The creature perfectly imitates certain sounds or even specific voices. The creature makes a Bluff check opposed by the listener’s Sense Motive check to recognize the mimicry, although if the listener isn’t familiar with the person or type of creatures mimicked, it takes a –8 penalty on its Sense Motive check. The creature has a +8 racial bonus on its Bluff check to mimic sounds (including accents and speech patterns, if a voice mimic) it has listened to for at least 10 minutes. The creature cannot duplicate the effects of magical abilities (such as bardic performance or a harpy’s captivating song), though it may be able to mimic the sound of those abilities. This ability does not allow the creature to speak or understand languages it doesn’t know.
