A Live Collossus. The ranks on his feet dig into the ground with each step, while his body is made out of foliage, moss and bark. With his giant "arm" he can reach into the distance and the giant insects living inside of him can sting and stun you so you can't move for a few secondsbefore it gets you.
It has huge flowers growing on his back, some are poisonous and can cause death, others have healing power and you can make quite a delicious tea out of it. ^^
S**t, I believe he spotted us!
Basically I just had a closer at the references and inspiration on the Rift homepage and made use of all the stuff in the video. Many people did not seem to pay attention. And I used magic cards for references. I tried to make it really fit into the game. And I believe one could use it.
Also I didn't see flowers on the other guys which makes this guy unique.
