Scrolls of Challenge[]
A Scroll of Challenge is a consumable item that can be used to open up a one-way portal to a random challenge area. Scrolls of Return are prohibited and if you die then the challenge ends without you being able to re-enter. They are only acquired by killing special mobs with the "Champion" affix who will then drop a scroll. When you use a Scroll of Challenge it will open up 1 of 4 possible challenges.
Champions Domain[]
The Champion's Domain is an area that will have a single boss for you to kill. After killing the boss 3 Golden Chests will appear.
The Rigged Vault[]
The Rigged Vault is an area with no enemies with chests spawned throughout. After entering you will have 20 seconds to loot the chests. Once the timer ends all chests are destroyed and all the loot on the ground that hasn't been picked up will vanish.
The Arena of Death[]
In this challenge you will face 5 waves total of enemies with each wave becoming slightly stronger. After 5 waves you will face a Boss Wave which will contain at least 2 Champion Mobs. After beating the Boss Wave 3 Golden Chests will spawn.
