Scáthach temporarily summons a massive gate to her shadow realm, and it sucks in all life forms in range. If the target fails to resist it with one's Mana or Luck stat, they're sucked into the gate and are instantly killed. Scáthach can choose specific targets on whether to allow them access or not. Even if resisted, the targets' mana is rapidly drained and they take major damage.
In the events of Fate/Grand Order during the North America Singularity, she attempts to forcibly send Cú Chulainn Alter to the Land of Shadows with it, but fails as he retaliates. However, she was able to escape from him by going through the gate and hide herself in the Land of Shadows until she recovers.
Gate of Skye (Scáthach Skadi)Edit
Gate of Skye: Gate to the Magical Realm Brimming with Death (死溢るる魔境への門, Shi Mitsuru Ruru Makyō e no Mon?) is the Noble Phantasm possessed by Scáthach Skadi, the fusion of Scáthach and Skadi brought about by the unique circumstances of the Norse Lostbelt. Scáthach Skadi, being primarily Skadi's personality, does not clearly understand why she uses Gate of Skye. She merely perceives the divine protection of the Norse gods is likely being employed through the power of the Noble Phantasm originating from her other self.
As with Scáthach, the Noble Phantasm summons a giant gateway that leads to the Land of Shadows, causing a portion of it, the "Fortress of Shadows", to make an appearance. Differing from the offensive usage of the normal Scáthach, all those Scáthach Skadi approves of within the effective rage will be bestowed great luck and blessings by the Fortress. It allows those loved by the Fortress of Shadows to defeat powerful enemies, even if they are normally powerless themselves. If properly employed during a regular Holy Grail War, it could bring about an "astonishing upset."
