Forged of steel grafted from Umbra's flesh, this elegant nikana unites with its Warframe to form a single being of seething purpose.

Skiajati is Excalibur Umbra's signature nikana, with the unique ability to turn its user invisible on finisher attacks. It was released in Update 23.0.

This weapon cannot be sold.


This weapon, along with Excalibur Umbra, is given during the penultimate mission of The Sacrifice at max rank, complete with a free weapon slot, a pre-installed Orokin Catalyst, and the mods Sacrificial Steel and Sacrificial Pressure fused to rank 5. A second Skiajati will not be given after replaying the quest.


This weapon deals primarily Slash b Slash damage.



Weapon LoadoutsEdit


  • All the mastery rank points that would normally be granted from ranking up the weapon will be automatically received upon acquiring it.
  • Despite its mastery rank of 11, players of lower ranks can acquire and use this weapon.
  • Finisher attacks with this weapon turn the user invisible for 5 seconds. Attacking or using an ability will break the invisibility, similar to the cloak provided by Shade and its Ghost precept.
    • The invisibility period is not affected by mods.
    • Performing a finisher while under the invisibility effect of the Skiajati will refresh the cloak's duration.
    • Invisibility is not affected by Nullifier bubbles.
  • Note that it's not possible to (re-)add an Umbra Pol polarity to a mod slot, so it's advised not to polarize the pre-existing ones.
  • The cloth piece is a fixed part of the sheath and not a removable cosmetic.


  • Σκιά (Skia) is Greek for shadow, while जाति (Jati) is Sanskrit for birth.
    • This can either tie in to the sword's relationship with Excalibur Umbra, with Umbra being Latin for shadow, or to the weapon's passive ability to cloak its user.
  • The weapon utilizes a similar model to the shikomizue or jotō katana, best described as a swordstick or staff sword.
  • According to its Codex entry, the Skiajati is a normal Nikana "grafted" from Umbra's flesh.
