Whahaha......
We can now make a Psion(Telepath) into a Stone Golem in an Instant manner with no issues on rulesy questions (takes a bit of work and some collaberating Wizards/Clerics, though):
1) Nullify Stone Golem's Magic Resistance by way of Stone to Flesh
2) Awaken Stone Golem via spell (There's a couple of ways around the casting time)
3) Nullify Stone Golem's Magic Resistance by way of Stone to Flesh again
4) Polymorph Stone Golem
5) Mind Switch, True, on the Polymorphed Stone Golem.
6) Permit polymorph to expire.
Well, okay - we could before, too:
1) Nullify Stone Golem's Magic Resistance by way of Stone to Flesh
2) Polymorph Stone Golem into an Animal
3) Awaken Polymorphed Stone Golem (by way of the Druid's Awaken spell).
4) Mind Switch, True, with the polymorphed Stone Golem
5) Permit Polymorph to expire
What do you get?
Construct Type (and all the benefits that entails - immunity to Mind Affecting effects, Darkvision, Low-light vision, immunity to death by Massive Damage, instant death at 0 HP, and so on), 20 foot move speed, AC 26 before equipment and spells, Large size (but that's what Compression is for), Strength 29, Dex 9, two Slam attacks at 2d10+9, DR 10/Adamantine, and Immunity to Magic. Also the ability to be completely healed by Transmute Mud to Rock.
Downside: Next time you die, you stay that way (Construct trait).
