A Duo is an instance designed for completion by two players working cooperatively. Currently, there are fourteen duos available in DC Universe Online.

AccessEdit

In order to enter a duo, players must queue up using the On Duty Menu (Default PC Key 'Y'). They will then be placed in a queue that searches for other players who wish to do the same duo, and be prompted to enter the instance.

Players must complete Emergency Response to gain access to duos and additional Combat Rating or DLC requirements must be met.

• Tier 1 duos are available to at level 30.
• Tier 2 duos require a Combat Rating of 43 to enter.
• Tier 3 duos require a Combat Rating of 53 to enter.

RewardsEdit

Upon completing a duo, players will receive Marks of Triumph, in addition to any loot the boss happens to drop. Additionally, if the duo was marked as Daily by a star, players will receive extra Marks. A player gets a weekly Award Box when he finishes a duo for the first time of the week.

• Completion of a Tier 1 Duo rewards 2 Marks of Triumph daily and Award Box weekly.
• Completion of a Tier 2 Duo rewards 10 Marks of Triumph daily and Award Box weekly.
