14. Heart Of The Beast: Cast this spell on a slain monster’s heart (or reasonably equivalent organ or portion), then consume it. At any time, you may take the devoured creature’s shape, once, for 10 minutes. You will retain some physical mark of this transformation afterwards.
Once again, Taichara hits it straight out of the park!
UPDATE: Ok, I posted too quickly. Here are some thoughts:
Heart of the Beast is clearly meant to allow you to assume the shape of creatures, but "monster" can be an ambiguous term; could the truly unscrupulous use this to mimic a murdered person?
Can you use Skyclad in conjunction with The Stars to Guide You? I'd certainly allow it.
