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.

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.
