Hello there,

Introduction:

[Excalibur] is probably your first Warframe in game. But Umbra is the guy you want. After many years collecting dust, I finally came here to update this dude, just because of latest changes in game and Lua's Prey Update. You thought this update was about [Voruna]? Wrong! It was all about [Grendel]'s Rework. And this is why I'm here... his ability called Noirish got super buffed. I'm going to use it here.

So... Howl all you want... you got plenty of energy for that
Build is created not only to Howl all you want

• Keep in mind to use Primary Emissive Color that can give you Heat proc, it will activate Archon Vitality Bonus - [Exalted Blade] that inflict a Heat status proc will inflict a second proc that deals the same damage

Passive:

[Excalibur] Umbra exhibits sentience, allowing him to remain active in combat even when a player uses Operator form, acting similarly to a Specter
Improved mastery in the Tenno art of the blade, receiving +10% Attack Speed and +10% Damage Bonuses for melee attacks while wielding Swords, Dual Swords, Nikanas, Rapiers, and Exalted Blade

Aura:

Default Madurai polarity let you use Steel Charge for more Melee Damage

Exilus:

• Primed Sure Footed is the best choice

Arcanes:

• Fury: +180% Melee Damage on Critical Hit for 18s
• Strike: +60% Attack Speed to melee on hit for 18s
• Energize: Energy replenish on Energy Orb pickup, 15s cooldown

• Avenger: +45% Critical Chance for 12s
• Molt Augmented: up to +60% Strength on kill
• Molt Efficiency: up to 36% Duration over a period of time while Shields are active

Archon Shards:

• Crimson Archon Shards (RED): +25% (+37.5%) Melee Critical Damage, or +10% (+15%) Ability Strength or +10% (+15%) Ability Duration
• Amber Archon Shards (YELLOW): any but Parkour Velocity, +25% (+37.5%) Casting Speed is always welcome
• Azure Archon Shards (BLUE): any but Shield Capacity

Focus School:

• Naramon for its Power Spike
• Zenurik for Energy Replenish
• Madurai for its Power Transfer and Sling Strength
• Vazarin for its Protective Sling

Any other Focus School for whatever reason you want to achieve

Loadout:

• StatStick for [Exalted Blade]: get a x12 combo before using the fourth ability Exalted Melees StatStick + Armor Strip
• [Excalibur Umbra]: Main Build Howl all you want...
• [Exalted Umbra Blade]: Blade Build ... It won't bring him back
• Companion - Your devoted servant - kavat that will serve you in many ways

Summary:

[Excalibur Umbra], one and only Umbra in the entire game, and probably hi will remain the only one, because "DE is busy with other things". Anyway, if you enjoyed playing Regular [Excalibur], you may want "upgraded" version, with full potential.

So... Enjoy!
