Warframe Guides

See Category:Excalibur Guides to read user-made guides on how to play this Warframe.


  • It costs less platinum to purchase him outright than to rush construction of the components and main blueprint.
  • He is the first of two Warframes with an unpolarized Aura slot, NekrosIcon272 Nekros being the second.
  • Excalibur is similar in design to Hayden Tenno's suit from Digital Extremes' previous game Dark Sector. This is further reinforced with the Proto-Armor Skin, which is a near-exact copy of that very suit.
  • Excalibur is named after the legendary sword of Arthur; King of the Britons. Many of his alternate helmets feature names based off Arthurian legend.
  • An Excalibur is shown being ripped apart by Alad V while wearing the Pendragon Helmet and the Immortal Skin in "The Profit", a trailer for the PS4 release of WARFRAME.
  • Prior to Update 14, Excalibur would use his equipped melee weapon when casting his abilities, regardless if it was impractical (casting RadialJavelin130xDark Radial Javelin with a Galatine o Galatine), nonsensical (SlashDash130xDark Slash Dashing with the Kogake0 Kogake) or impossible (using any of his abilities without a melee weapon equipped). Update 14 changed this by making him generate an ethereal DESkana Skana when using his abilities, rather than using his melee weapon.
    • If there was no melee weapon equipped, then Excalibur would use the currently equipped weapon. (i.e. Radial Javelin with a Braton Braton). Humorously, ethereal copies of that weapon would appear upon using Radial Javelin.
  • Before Hotfix 22.8.3, Excalibur parts blueprints dropped from Ambulas on Hades, Pluto. This is now the drop location of TrinityIcon272 Trinity.
  • In Update 23.0, Excalibur's ExaltedBlade130xDark Exalted Blade received a physical form to allow for customization, replacing its previous form which was made from pure energy.
    • The same update also allowed players to directly mod EWExaltedBlade Exalted Blade.
  • According to the Official Tenno Alphabet Cipher, the design on Excalibur's right shoulder is in fact a word that spells out "Hayden Tenno". The same word can be found on top of Excalibur's head.
  • Excalibur's default helmet was added to the real-time strategy game Airmech as a victory gesture after Warframe beating Airmech in a vote of popularity between the two.
    • This was originally intended to be Excalibur Prime's default helmet, however the reason for this change is unknown.
  • Excalibur's default helmet (along with the default helmets of LokiIcon272 Loki and ChromaIcon272 Chroma) are available as unlockable antenna toppers in Rocket League.
  • Excalibur is the only frame that has 12 alternate helmets (with Excalibur Prime's being exclusive).

The Sentients had won. They had turned our weapons, our technology, against us. The more advanced we became, the greater our losses. The war was over unless we found a new way. In our desperation we turned to the Void. The blinding night, the hellspace where our science and reason failed.

We took the twisted few that had returned from that place. We built a frame around them, a conduit of their affliction. Gave them the weapons of the old ways. Gun and blade. A new warrior, a new code was born. These rejects, these Tenno, became our saviors. Warrior-Gods cast in steel and fury striking our enemies in a way they could never comprehend. Excalibur was the first.

Excalibur Prime is the epitome of mobility and offense, and features the same abilities as Excalibur, but has unique mod polarities installed allowing for greater customization.

—In-game Description

Release Date: December 18th, 2012

Excalibur Prime is the Primed variant of ExcaliburIcon272 Excalibur, possessing higher armor and energy, as well as an additional Madurai Pol polarity and a Madurai Pol Aura polarity. Excalibur Prime is a Founders-exclusive Warframe released alongside LatoPrime Lato Prime and SkanaPrime Skana Prime.


Excalibur Prime was only obtainable by upgrading a Warframe account to Founders status of Hunter or greater, which is no longer available. He came with his own Warframe slot and was already augmented with an Orokin Reactor.

The Founders' program closed on the 1st of November, 2013, as announced on the warframe forums. This closure is inclusive of pack upgrades.


  • Excalibur Prime, compared to ExcaliburIcon272 Excalibur:
    • Higher Armor (300 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)
  • Excalibur Prime, compared to Excalibur UmbraIcon272 Excalibur Umbra:
    • Different Polarities (Vazarin PolMadurai PolMadurai Pol vs. Madurai PolUmbra PolUmbra PolUmbra Pol)
  • As a Prime Warframe, Excalibur 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.


  • Excalibur Prime is the first Prime Warframe in the game.
    • He is also the first Prime Warframe to come with two different polarities, as opposed to one. This was followed by Ember PrimeIcon272 Ember Prime and Loki PrimeIcon272 Loki Prime.
  • There is a statue of Excalibur Prime inside the Orokin Derelict vaults, and one of the Lua Spy vaults.
    • Interestingly, at the start of Update 11.0 Excalibur Prime was given a short-lived full body skin called "Alabaster", which was explained by Digital Extremes as a test skin that was released by mistake. The skin's texture was similar to said Vault statues.
  • Compared to the later prime Warframes, Excalibur Prime has the least cosmetic difference compared to his standard counterpart, with the only significant additions being the Void Key-shaped emblem on his helmet and golden blades along his forearms.
  • When he was released, it was widely believed that Excalibur Prime had a slightly higher shield recharge rate compared to the non-prime variant.
    • While the existence of this feature can neither be confirmed, nor denied, Excalibur Prime currently does not possess this stat change.
  • Much like how Update 14.0 gave the standard Excalibur an ethereal DESkana Skana when using his abilities, Excalibur Prime uses an ethereal SkanaPrime Skana Prime with his abilities, which was also added in the same update.
  • On the Chinese build of Warframe, Excalibur Umbra Prime serves as a stand-in for Excalibur Prime.

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

Ferocious and untamed, Umbra’s fury is second only to his mastery of the blade.

Release Date: June 15th, 2018

Excalibur Umbra is the Umbra variant of ExcaliburIcon272 Excalibur, sporting higher armor and energy, as well as three Umbra Pol polarities while losing a Vazarin Pol. Unique to Umbra is his display of sentience, allowing him to fight on his own when not piloted by the Operator.

He was first released in the Chinese build of WARFRAME as ExcaliburUmbra Excalibur Umbra Prime and was later added to the Global build in Update 23.0. He can be acquired through the The Sacrifice quest.

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. A second blueprint will not be given on replays.

At the end of the quest, players will receive Excalibur Umbra at Rank 30 with a free, pre-installed Orokin Reactor, and Warframe slot.


The Sacrifice

But you won't have to imagine. A lovingly cultured Infestation swarms within your blood. Your transformation has begun, reshaping you into a sacred surrogate of the unholy Tenno... A Warframe with but a Single. Burning. Memory. It is... a miracle! But all miracles require 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.

--We had created monsters we couldn't control. We drugged them, tortured them, eviscerated them... We brutalized their minds... but it did not work. Until they came. And it was not their force of will - not their Void devilry - not their alien darkness... It was something else. It was that somehow, from within the derelict-horror, they had learned a way to see inside an ugly, broken thing-- And take away its pain.


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.

  • Umbra, along with the Skiajati Skiajati, 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 PolUmbra polarity. He also comes with 3 Umbral Mods: Mod TT 20pxUmbral Intensify, Mod TT 20pxUmbral Fiber, and Mod TT 20pxUmbral Vitality fusioned to rank 5 out of 10. His Skiajati Skiajati Nikana and Exalted Umbra Blade each have two Umbra Pol polarity slots and come with Mod TT 20pxSacrificial Pressure and Mod TT 20pxSacrificial Steel equipped.
  • In place of RadialBlind130xDark Radial Blind, Umbra has RadialHowl130xDark Radial Howl, 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.


  • Umbra is the Latin word for "shadow".
  • Excalibur Umbra is the first Umbra variant of a Warframe to be released in WARFRAME.
  • Excalibur Umbra is the only quest Warframe that cannot be purchased from the Market or be sold.
  • Excalibur Umbra's agile and noble animations are the only animations that are able to be used on other Warframes without prior purchase.
  • According to its Codex entry, the Skiajati, Umbra's signature weapon, is a Katana Nikana "grafted" from Umbra's flesh.
  • In the Chinese build, Excalibur Umbra originated as part of their Founder's pack exclusive, as Excalibur Umbra Prime, gameplay-wise identical to Excalibur Prime. The pack also included the PrimeNikana Nikana Prime and the PrimeLiDagger Spira Prime, as well as the Gauvan Prime Sekhara, a shoulder accessory obtainable only through that Founder pack.
  • Upon release, Excalibur Umbra had the passive ability of Prime Warframes to gain energy from Orokin Void Death Orbs, as an erroneous leftover from his data origins as Excalibur Umbra Prime. This was later removed in Hotfix 23.0.3.
  • Umbra utilizes a different sword design for his ExaltedBlade130xDark Exalted Blade, which is named Exalted Umbra Blade. The stats for both weapons, however, are identical.
  • Upon completion of The Sacrifice quest, players will receive an Excalibur Umbra-exclusive Excalibur Umbra Sunder Helmet in their inbox, which is a battle-damaged version of the regular Umbra helmet.
  • Excalibur Umbra is the first Warframe confirmed to originally be a "human being". He is also the first frame to have had his face exposed due to damage to his helmet.
    • Ballas confirms that Warframes are created from human subjects as Infested-hybrids cultivated by the Helminth.
  • When interacting with Baro Ki'Teer, Baro will treat Umbra as he would be any other non-Prime frame.
  • Umbra's scarf and torso lining, along with his Orokin ornaments, remain visible when other Excalibur skins are equipped, similar to the Prime details of Prime Warframes when using TennoGen skins. Hotfix 25.4.1 added a "Toggle Prime Details" option, which removes his scarf, torso lining and ornaments on other skins when toggled on.
  • Looking closely, Shadow Stalker uses a unique variant of Excalibur Umbra's body, which lacks the Orokin ornaments and Umbra's signature scarf, along with a different loincloth design.
  • In the "The Sacrifice" teaser of TennoCon 2017, Umbra wielded a regular Nikana on the Orokin Moon tileset.
  • It was revealed at TennoCon 2018's Sound Panel that Excalibur Umbra's howls were voiced by [DE]Steve Sinclair, Game Director of Warframe.[1]

ExcaliburIcon272 Excalibur has improved mastery in the Tenno art of the blade, receiving +10% attack speed and +10% damage bonuses for melee attacks while wielding the following weapons:

Excalibur UmbraIcon272 Excalibur Umbra exhibits sentience, allowing him to remain active in combat even when a player uses Operator form, acting similarly to a Specter.

  • Umbra can receive damage and healing in his specter form. Health and shields lost in his specter form will not be restored upon returning to Umbra unless all of Umbra's health is depleted.
  • Once all of Umbra's health is depleted, he will stop moving or attacking.
    • The player does not die or lose a revive, however, if Umbra's health is depleted.
  • Umbra can use any equipped weapon and most abilities, which will take into account of any mods installed. Neither of these actions will consume ammunition nor energy, however.
  • When enemies come within 3 meters of Umbra, he will automatically switch to the equipped melee weapon.
    • If no melee weapon is equipped, Umbra will not attack enemies who approach him, but will still cast abilities.
  • If Umbra falls down a bottomless pit while in Specter mode, he will not be teleported back and will remain missing until players return to Warframe mode.

Radial Blind is also replaced with Radial Howl:

RadialHowlMod RadialHowl
Radial Howl
Let out ferocious howl that stuns nearby enemies and causes Sentients to shed any built up resistances.
Duration:7 / 10 / 12 / 15 s
Range:8 / 12 / 15 / 25 m

  • Excalibur Umbra howls, releasing an intense flash of light that affects enemies within 8 / 12 / 15 / 25 meters and stuns them for 7 / 10 / 12 / 15 seconds.
    • Duration is affected by Ability Duration.
    • Radius is affected by Ability Range.
    • Stunned enemies are vulnerable to melee finishers and susceptible to stealth damage bonus.
    • Radial Howl will not affect enemies behind obstacles in the environment unless Excalibur Umbra has line of sight, or unless the enemy is aware of Excalibur Umbra within a short period of time (e.g., an enemy that spots Excalibur Umbra and runs out of view is still susceptible to Radial Howl if the ability is used within a small time frame).
  • Enemies affected by the ability are stunned for the entire duration.
    • Bosses are still able to move, attack, or use abilities while affected by the ability.
    • Bosses will attack the player's last known location and will follow the sound of gunfire.
    • Successive casts will reduce the duration of the ability's effect on bosses.
  • Sentient fighters and Shadow Stalker will have their resistances removed if they are affected by Radial Howl.
  • Security cameras will deactivate their laser barriers for the duration.
  • Affected enemies have smoke diffusing from their eyes or similar body part for the effect's duration.
  • Can be used while running, attacking, blocking, jumping, sliding, forward flipping, wall running or clinging to a wall.
  • Has a cast time of 0.9 seconds, affected by Mod TT 20pxNatural Talent and Mod TT 20pxSpeed Drift.

Main article: Radiant Finish

Radiant Finish is a Warframe Augment Mod for ExcaliburIcon272 Excalibur that increases the damage dealt by Finishers against enemies affected by RadialBlind130xDark Radial Blind and RadialHowl130xDark Radial Howl.

Rank Damage by Finisher Cost
0 150% 6
1 200% 7
2 250% 8
3 300% 9

Tips & Tricks
  • Radial Howl lets players quickly disable enemies, especially if they are surrounded. This allows players to either escape or to deal with the enemies.
  • Radial Howl allows the removal of Sentient resistances without having to switch to Operator mode.

  • If Excalibur Umbra managed to use an item (such as a Life Support in Survival) while casting the ability, Radial Howl will be cast twice: First, in a slowed animation and the second as the actual ability. Both animations still counts as a single Radial Howl.

    Update 28.1

    Xoris Interaction Changes

    Certain Warframe Abilities and Exalted weapons will now reset the Melee Combo Counter only if the Xoris is being used. The overwhelming Damage output of certain Warframe Abilities was not our intention with an infinite Melee Combo weapon, and the conversation of ‘Xoris or you’re doing it wrong’ is greatly restrictive in terms of player choice.
