Oddix

Oddix are gargantuan elemental creatures. They are not vulnerable to lightning, but thunder itself damages them. Non-magical weapons not made with adamantine or other special metals will have a hard time trying to do more than scratch them.

They are immune to poison and pertification, and can see in the dark and sense tremors and magic. The Oddix can glide through non-magical, un-worked earth and stone without disturbing any of the material that it moves through.

Oddix are strong, powerful beings capable of destroying building structures.

So long as the Oddix is not exposed to fire for an extended period of time, it can regenerate due to the properties of the moss that grows on it.

The Oddix can cast a number of magical spells and use several plant-based abilities, as well as straight up hit things.
