Abilities
Passive: Umbra exhibits sentience in combat without Transference control. Attacks 10% faster and deals 10% more damage while wielding swords.
💡 Excalibur Umbra keeps Excalibur's abilities except the 2: Radial Howl blinds or staggers like Radial Blind, and also strips the resistances of Sentients and the Shadow Stalker. Its Exalted Umbra Blade has the same stats as Exalted Blade, so the build is the same. It has 3 Umbra polarity slots (plus 1 Madurai) and comes with 3 Umbral mods (Intensify, Fiber, Vitality). Its passive adds Sentience: it keeps fighting on its own while you play as the Operator. At rank 30: 315 armor and 225 energy (Excalibur: 240 and 150). It comes from The Sacrifice quest, one per account.

How to play
Cast Radial Blind (2) to blind the room, then summon Exalted Blade (4) and swing: every swing sends out an energy wave that passes through enemies, so blinded targets die at range. Slash Dash (1) crosses the room and each hit also releases a wave. The blade costs 25 energy to summon and 2.5 per second to keep: recast Radial Blind whenever enemies start shooting again.

Excalibur FAQ
What is the best Excalibur build?
Everything revolves around Exalted Blade (4): 25 energy to cast, then 2.5 per second, and every swing sends out an energy wave that passes through enemies. Steel Charge aura (+60% melee damage), which applies to the blade; Chromatic Blade (+300% Status Chance at max rank) to give it an element; Radial Blind (2) to blind the room before you swing. The blade's own mod grid is above.
Do my melee weapon's mods apply to Exalted Blade?
No. Since Update 23, Exalted Blade has its own mod slots in the Arsenal, and since Update 38.5 its own Arcane slot (Melee Influence, for example). It forces its own stance, which ranks up with the ability. Some Warframe mods count too: Ability Strength, Duration and Efficiency.
Which color for Chromatic Blade?
The element follows Excalibur's primary emission color; other colors (secondary emission and so on) do nothing. White, grey, black or faded colors = Cold; blues and purples = Electricity; red, magenta, brown, orange, bright yellow = Heat; green, lime, teal, dark yellow = Toxin. The element replaces physical damage (physical mods stop counting) and combines with elemental mods: green emission + an Electricity mod = Corrosive.
Excalibur, Excalibur Prime or Excalibur Umbra: does the build change?
Prime: same abilities, same build. At rank 30 it has 315 armor (240 for Excalibur), 225 energy (150), starts with 100 energy (50), a Madurai aura and 3 innate polarities (2 on Excalibur). It was a Founders exclusive and can no longer be obtained. Umbra: same passive (+10% damage and attack speed with swords) and same abilities except the 2: Radial Howl, which blinds or staggers and also strips the resistances of Sentients and the Shadow Stalker. Its Exalted Umbra Blade has the same stats; its 3 Umbra slots take Umbral mods. It comes from The Sacrifice quest, one per account.
