After teaching her for an hour, I figured it out.
This dragon's kind of a blockhead.
'The classic type who relies solely on raw mana and acts cocky.'
She uses mana so recklessly that her circuits keep getting messed up.
No wonder her magic doesn't work properly.
An average mage might get away with it.
But for a dragon with an absurd amount of mana, it's a real problem.
"This is pretty bad."
"Sh-shut up! It's because I'm just too exceptional."
"...That's not entirely wrong, I guess."
To pull off such a polymorph with such shoddy mana control.
It's gotta be the result of sheer effort.
Maybe her actual talent is just average.
It's just that my standards are high from dealing with witches like Circe.
"How long did it take you to master polymorphing naturally?"
"...About 50 years, maybe."
"Aha."
In human terms, that's practically a lifetime.
She spent that long and her horns still keep changing shape due to instability?
