Shapeshift

[Chris Rice]

I get the impression that the Wizard will often use the spell on another person or creature. If they use it on themselves they'd be very foolish to choose a form with a low IQ as that would leave them stuck and potentially unable to turn back.

On your second point; I wouldn't allow Remove Thrown Spell to work against Shapeshifting. Although the Spell itself is a thrown spell, the effect is permanent, so once it has taken effect it is no longer magic - you've actually turned into a frog or whatever. It does mention that Dissolve Enchantment will work, as that is designed to remove permanent Spell effects.
