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 UmbraIcon272.png Excalibur Umbra's signature nikana, with the unique ability to turn its user invisible on finisher attacks.

This weapon cannot be sold.


  • This weapon deals primarily DmgSlashSmall64.png Slash damage.
  • Finishers temporarily turn the user invisible for 5 seconds.
  • Two innate Umbra Pol.png polarities.


  • Highest status chance and attack speed of all nikanas.
  • Normal Attack
    • High attack speed
    • Above average attack range
    • Above average status chance
    • Above average crit multiplier


  • Second lowest base damage of all nikanas, after Nikana.png Nikana.
  • Normal Attack
    • Below average damage
    • Very low disposition


This weapon, along with Excalibur UmbraIcon272.png 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 Mod TT 20px.png Sacrificial Steel and Mod TT 20px.png Sacrificial Pressure fused to rank 5. A second Skiajati will not be given after replaying the quest.


  • 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 Mod TT 20px.png 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.
    • AshIcon272.png Ash's BladeStorm130xDark.png Blade Storm does not activate the invisibility effect.
  • The cloth piece is a fixed part of the sheath and not a removable cosmetic.
  • Due to the special ability of this weapon, stances with finishers in them would be useful in proccing the effect. However, there are no Nikana stances containing finishers.


  • Σκιά (Skia) is Greek for shadow, while जाति (Jati) is Sanskrit for birth.
    • This can either tie into the sword's relationship with Excalibur Umbra, with Umbra being Latin for shadow or to the weapon's passive ability to cloak its user.
  • An alternative, simpler, interpretation uses यजति (Yajati), Sanskrit for sacrifice, reflecting the name and theme of the quest. This way, however, the origin of the sk- radical is left unclear.
    • The स्क character of Devanagari makes the sk- sound, making स्कयजति a phonetical approximation of the weapon's name.
    • The word सखि (Sakhi) is Sanskrit for friend.
  • 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.
