"Those who have performed the Dragon Communion will find their humanity slowly slipping away. Once they fully succumb to their fate, they are left no more than wyrms that crawl the earth."

Uh oh... This is a problem...

My tarnished wishes to become a dragon and is vain enough to think she will overcome the negative effects of the dragon heart consumption.

...however, she does have an.... episode. I imagine the transformation to Magma Wyrm to be subtle until you sorta have a... heart attack (?) (HAH!) that triggers a full blown metamorphosis.

In her case she does manage to... resist it and revert back to a human form... but she does get the left side of her face and jaw permanently altered to look like a dragon jaw and has scales on her left arm and on other parts of her left body.

Now aware that she is not immune of the curse, this won't stop her... She'll just have to get some other power to cancel the curse...
