Dark Dimension Rewards vary from each difficulty. Generally, you can obtain Gear Materials, Gold, Orb Fragments, Promotion Credits, and Elite Credits to further upgrade your characters. Premium Dark Dimension Rewards include character shards for Ultron, Doctor Doom, and Dormammu. Additionally, by completing Dark Dimension difficulties multiple times, an Achievement can be completed to obtain a Profile Border.

Note: Profile Border Upgrades are irreversible. Choose wisely.
