From the shadow of the long night emerges a new Excalibur.

Release Date: August 7th, 2015

Excalibur Umbra Prime is the Founder exclusive Warframe for the Chinese build and serves as a stand-in for Excalibur PrimeIcon272 Excalibur Prime, which was only available in the Global build. It was released along with PrimeLiDagger Spira Prime and PrimeNikana Nikana Prime.

The visual likeness of the Warframe was later added to the Global build as Excalibur UmbraIcon272 Excalibur Umbra in Update 23.0. Unlike Umbra Prime, it has Radial Howl, more armor, and Sentience but lacks the Death Orb energy passive that all Prime frames have.


Excalibur Umbra Prime was originally purchasable by players of WARFRAME (China), with or without PrimeLiDagger Spira Prime and PrimeNikana Nikana Prime, as part of the China Founders pack. This offer is no longer available.

The China Founders' program was closed alongside the release of The Sacrifice in WARFRAME (China) on April 11th, 2019. China Founders were compensated with an Umbra-exclusive Excalibur Umbra Beast Helmet, corresponding light and dark Glyphs of the helmet, a Legendary Core, and an Excalibur Umbra Noggle.

    • Different Aura Polarity (Madurai Pol vs. None)

  • As a Prime Warframe, Excalibur Umbra Prime possesses a special passive ability where contact with an Orokin Void Death Orb will make them release an energy pulse that grants 250 Energy to all nearby allies. This effect can only occur once per Death Orb, and can occur even if the Death Orb has been previously destroyed.
