He doesn't get access to Ex abilities, which is why I argued that he can't lower it. I would treat SR for the mage in the tarrasque's body as always on.Felix said:Does the mage gain access to Ex abilities when he magic jars the T? I believe so. (short on time to look up the SRD)
If the mage gains access to SR, can he raise and lower it. Yes, he can.
So really the question is, what does the spell say about getting the target's abilities? If he get Ex abilities, mage gets SR, mage can lower SR.
...If nobody else looks the spell up, I will when I get a chance....
