Six days of madness are planned for Bethesda’s card game.

You may think that releasing a card game in Blizzard-occupied territory is a proof of madness. But Bethesda’s developers think differently and recently announced The Chaos Arena event for The Elder Scrolls: Legends.

It takes place from December 14 through December 19. During this time arena’s artstyle will change and there’ll be different lane conditions and active scenarios. “When you summon a creature in this lane, transform it into a random animal,” is a good example.

To accompany this event, there is a promotional set of cards available in The Elder Scrolls: Legends’ store. These cards aren’t randomized like a normal pack of cards and you can read about them in the official blog note. You’ll also get a free card pack if you simply sign-in during the event.
