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 Mod TT 20pxGhost 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.
  • 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 can be useful in proccing the effect. One such as Tranquil Cleave.


  • 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.
  • An alternative, simpler, intepretation 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 Devaganari 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.
