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

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

The visual likeness of the Warframe was later added to the Global build as Excalibur Umbra in Update 23.0. Unlike Umbra Prime, it has Radial Howl, more armor, and Sentience.


Excalibur Umbra Prime is purchasable for players of WARFRAME (China), with or without Spira Prime and Nikana Prime, as part of the Founders pack on the following Changyou link (CHI).


  • Excalibur Umbra Prime, compared to Excalibur:
    • Higher Armor (250 vs. 225)
    • Higher Energy (150/225 vs. 100/150)
    • Different Polarities (Vazarin PolMadurai PolMadurai Pol vs. Vazarin PolMadurai Pol)
    • Different Aura Polarity (Madurai Pol vs. None)
  • Unlike Excalibur Umbra, Excalibur Umbra Prime's stats and abilities are identical to Excalibur Prime's.
    • In Update 23.0, Excalibur Prime's armor was increased from 250 to 300, making this the only difference between the Prime and Umbra Prime.
  • 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.
  • Just like Excalibur Prime, Excalibur Umbra Prime's Exalted Blade has a form similar to Skana Prime.
  • Players who purchase the Founders pack will receive the WARFRAME (China)-exclusive Gauvan Prime Sekhara, regardless of the pack's tier.
