A shapeshifted wyrm was only similar to a true one in terms of appearance. Its dragon's breath brought about by the dragon blood was also good for defense and withstanding magic attacks, thus allowing it to perform perfectly. It was even said the Druids that shapeshifted into wyrms could use the powerful dragon language magic just like true wyrms.
Shapeshifting into wyrms wasn't the peak of the Wild Druids' power. It was said that after reaching level-22, Wild Druids could still shapeshift into every kind of powerful prehistoric magical beasts in a short period of time. Those beasts were formidable creatures that shared this continent with ancient wyrms and the Titans during prehistoric times.
Even Lin Li wondered what the Wild Druids could shapeshift into after reaching Sanctuary-realm. Could it be ancient wyrms?
