Magic jar Question

[puksone]

Hi,

when I fight in a room with my group against some enemies and i use magic jar could it happen that i take over the body of an ally (cause its random which body i take over)?
so is friendly fire possible?

Where in the spell description does it say the target is random?

I see no reason that you COULDN'T use it on an ally. Whether or not they would still consider you ally after the fact is circumstantial.

Yes, this is most certainly a possibility, and it is one of the few drawbacks of the spell.

You can only discern if the is more than 4 HD between the creatures, and whether they are powered by positive or negative energy.
