The Dex Dakra was released in commemoration of WARFRAME's 2nd Year Anniversary. It is obtainable through yearly anniversaries in March via Alerts, complete with a free weapon slot and a pre-installed Orokin Catalyst.
Despite being a (hypothetical) variant of the Dakra PrimeDakra Prime, the two weapons do not share Riven Mods; they both have their dedicated Rivens.
While related to the Dakra PrimeDakra Prime due to its similar name and design as a saber, the Dex Dakra is a Dual Sword instead of being a single Sword weapon.
When performing a ground slam, the Dex Dakra features a unique animation where energy ribbons emanate from the Warframe, along with a visible shock-wave being emitted from the weapon.
For a short period of time following its release, the Dex Dakra had no Stance polarity before it was fixed in an undocumented hotfix.
