Release Date: June 15th, 2018
Excalibur Umbra is the Umbra variant of , sporting higher armor and energy, as well as three polarities while losing a . Unique to Umbra is his display of sentience, allowing him to fight on his own when not piloted by the Operator.
The blueprint for Excalibur Umbra is given to players upon completing the first mission of The Sacrifice quest, and the ability to build the Warframe is granted on completing the second mission. Unlike other Warframes, Umbra requires no further components and is crafted entirely from the single blueprint. However, even after being crafted, he cannot be used until the penultimate mission, where he is automatically Rank 30 with a free, pre-installed Orokin Reactor and Warframe slot.
A second blueprint will not be given on replays. Also unlike other quest-tied warframe, Cephalon Simaris does not sell Excalibur Umbra blueprints. Thus the player can only own one copy of Excalibur Umbra.

- Umbra, along with the , will be obtained by the player already fully ranked. All the Mastery Rank points that would normally be granted from ranking up Warframe and weapon will be automatically received upon acquiring them.
- Due to their unique nature both are also unable to be sold from the inventory.
- Excalibur Umbra comes with three mod slots polarized with the unique Umbra polarity. He also comes with 3 Umbral Mods: , , and fusioned to rank 5 out of 10. His Nikana and Exalted Umbra Blade each have two polarity slots and come with and equipped.
- In place of , Umbra has , which not only blinds enemies, but also removes any active damage resistances from Sentient units and Shadow Stalker within range.
- Unlike other Warframes, Excalibur Umbra's sentience allows him to remain active after using Transference, supporting the Operator with abilities and equipped weapons. However, Umbra can be damaged, and will stop moving once all of his health is depleted.
- Excalibur Umbra is incapable of using Arch-guns when in autonomous mode, as transferring out with the Operator will make him switch back to using his primary weapon.
Due to Umbra's sentient passive, the following bugs can be observed:
- If Exalted Blade is used and the player goes into Operator, on Transference into Umbra the ability will be toggled off. The same happens with any subsumed channeled ability like Silence, Gloom, etc.
- If Mania applies the Lifted status effect on Umbra while Exalted Blade is active and the player switches to Operator and back into Umbra, he will be unable to use both Exalted Blade and the equipped melee weapon. Only the first few frames of the animation will play out, before the attack is canceled.
- If Combo Counter is built with Weeping Wounds, Blood Rush or the Gladiator set bonus and Power Spike is used to maintain it, once the player switches to Exalted Blade and hits at least one enemy then let its combo duration reset, either on its own over time or by using a Heavy Attack, he will lose the Gladiator set bonus applying to Exalted Blade in addition to Weeping Wounds, Blood Rush and the Gladiator set bonus applying to the equipped melee weapon, even if combo remains on it. This seems to be the case for all exalted weapons.
In order for those mods to begin working properly again, the player must either use a Heavy Attack on the equipped melee weapon to lose all combo or wait for Power Spike to drop the combo to its previous multiplier.
- Main article: The Sacrifice
Excalibur Umbra was originally an Orokin Dax soldier who was punished by Ballas for attempting to interfere with his betrayal. The soldier was deliberately exposed to the Infestation to become an anti-Sentient weapon, a "miracle" that requires "sacrifice", and was fitted with a unique Transference Bolt that forced him to obey Ballas's whims. He was then psychologically tortured into rote obedience by forcing him to kill his son, Isaah.
As a result of Umbra's torment, he retains most of his sentience and is capable of acting on his own without the Tenno's control, even initially rejecting the Operator's Transference and going rogue. Umbra also carries the memories of his final moments before transforming into a Warframe, which the Operator discovers to contain codes that unlock Ballas's Vitruvian recordings of the Sentient's betrayal, the creation of Warframes, and the Tenno.
Umbra is first seen in a courtyard on Earth battling his creator and his allied Sentients, but due to Transference influence he is unable to disobey Ballas, allowing him to be easily destroyed by Natah. The Operator discovers Umbra's remains on Earth, which leads them to a containment cell on Lua housing Ballas's Vitruvian, allowing the Operator to rebuild Umbra. However, Umbra immediately goes rogue and flees across the solar system, but not before the Operator taps into his memories.
After seeing all of Umbra's memories, the Operator reassures Umbra that they will fight Ballas together. Upon seeing this act of compassion, Umbra calms down and finally accepts the Operator's Transference. Together they battle Ballas on Earth, whose attempts to subdue Umbra prove futile when the Operator's Transference overpowers Ballas's control, allowing Umbra to wound his creator.
