[Video in Spanish, sorry]
New champion has been teased, A DARKIN Champion. Weapon of choice is a scythe. We normally dont get any teases from the Chinese region or South East Asian "borders" of the world, which made me doubt if this info is true, HOWEVER, this youtuber is a viable source of information.
There are multiple videos already out there on the internet, but this youtuber only managed to find screenshots.
The champion DOES transform.
Here is the video for those wondering.
