Again Piranha Bytes has released new information, a screenshot, picture of the polymesh and an artwork of a monster from their game at the Elex Facebook page, this time of the Skex.[1][2]
You can see them below!

According to legend, the Skex once had a bright coat and real wings. But nowadays the Skex is just known as an aggressive and haggard runner. If there is no way of escape, beware of it's razor-sharp mandible.
Despite his haggard appearance, the Skex is a very robust creature and has spread to many countries of Magalan. Especially when the Skex come across in small groups, you shouldn't provoke them. As a voracious omnivore, the Skex leaves nothing left from his foes.
