The Chaos Arena is an event in The Elder Scrolls Legends. It is centered around Sheogorath and features an updated temporary Arena and ten new cards. All players who log in during the event get a free core set card pack, to be delivered after the event.
The first Chaos Arena took place from December 14, 2016 until December 20, 2016, and it was popular enough that it was made a monthly event.
Ten promotional cards have been added to all Arena modes, and are available to be purchased as a set during the event as the Madhouse Collection:
- Altar of Despair (Legendary Support)
- Forsaken Champion (Epic Reachman)
- Illusory Mimic (Epic Spirit)
- Close Call (Rare Action)
- Gardener of Swords (Rare Redguard)
- Ring of Imaginary Might (Rare Item)
- Shivering Apothecary (Rare Imperial)
- Stoneshard Orc (Rare Orc)
- Swindler's Market (Rare Support)
- Merchant's Camel (Common Beast)
Two special offers are added to the store for the duration of the event, purchasable with money or in-game gold:
- Madhouse Collection - 10 promotional cards (three copies of each) and an Arena ticket
- Mad Prince Pack - 5 core set packs and alternate art for Hive Defender, Sharpshooter Scout, and Crushing Blow
Every match features a special scenario or lane type: both existing and new ones. The avatar art is humorously edited, and the lanes feature art specific to the type of lane, as well. Standard modes are still available during the event.
