From Bethesda:
Today The Elder Scrolls: Legends descends into chaos as Sheogorath, the Elder Scrolls’ legendary Daedric Prince of Madness, introduces Chaos Arena, an optional new PvP mode that tosses one or more random special scenarios or lane rules into each match. Players will need to adapt their strategies on the fly in every game, accounting for moving cards, surprising bonuses, and possibly crippling effects.
The Chaos Arena special event is live now and will continue until December 19. A full description of the Lane Rules and Scenarios can be found here.
In conjunction with Chaos Arena, a new set of special cards – the Madhouse Collection – has also been released, providing a fresh set of strategic options for players for use in all game modes. Purchasing the Madhouse Collection will earn players three copies of each card as well as an Arena Ticket so players can try Chaos Arena right away. The Madhouse Collection cards have been added to all Arena modes, including Sheogorath’s bizarre Chaos Arena. These cards are now available for purchase either with in-game gold or for money through the store.
A full description of the Madhouse Collection can be found here.
