Aengoth

Or you know, illusion.

one of these is not like the other

Wouldn't the practice of "turning" oneself into an object be excessively difficult for even a top ranked illusion mage. It would first require the time and energy, keeping in mind that mana is finite, to make a large percentage of oneself invisible. Then it would require the time and energy to then create the image of a flower pot. Just seems like a bit much considering the limits on other forms of magic.
