This creature is intended for DM use to fit the story of any campaign, so feel free to change any facts about about the dragon for your use. The Tangled Dragon is a normal dragon, coated by plants by a high ranking spellcaster. The Tangled Dragon does not have a mind of its own and is directly controlled by the one who created it. The spell to make one requires years of experience and longer the dragon lasts, the more it will take to keep the spell, and creature alive. However, if the caster in control of the dragon dies, the spell does not die and the dragon inside gains the mind of the dragon inside and stays in it's new plant body.
