Gambanteinn Valhalla

is a Noble Phantasm owned by Odin, and used by Cú Chulainn in his Caster form.
Gambanteinn Valhalla sets up a "well" as a meditative field to consecrate an area. Using it, Cú Chulainn was able to create an anti-curse barrier that destroyed the cursed hands of Cernunnos and made it possible for the Storm Border to approach Cernunnos's body. The price of this Noble Phantasm's use is it costs Cú Chulainn his eye, just as Odin sacrificed his eye at .Fate/Grand Order: Cosmos in the Lostbelt - Avalon le Fae: Fae Round Table Domain - Section 29: A Certain Prophecy
