Paragon players will be able to take part in the Shadow's Eve event starting on October 11th and running through November 6th. Players can earn Shadow's Eve chests that contain in-game items as well as themed skins and banners.
The new skins are for Narbash, Wukong and Yin. In addition, one of last year's skins will be made available each of the three weeks of the event.
There will also be a special Shadow's Eve Mega Bundle that contains all of the event skins and banners plus "variants" on each that are only available through the bundle.
You can learn more on the Paragon site.
