Skadi is a Diviner weapon that appears in Riviera: The Promised Land. It is wielded by Malice and is considered an axe type of weapon despite such a weapon type not existing in the game. Skadi's attacks are of the Ice element. It is explicitly stated by Hector that he crafted it himself in order to make Malice think she was a legitimate Grim Angel. Skadi appears to have some kind of relation to Einherjar, as they resonate when in close proximity of each other; the first time this occurred was during the encounter with Malice at Lacrima Castle, which prompted her retreat.
Skadi P-2 is a presumed prototype of Skadi, and appeared in Yggdra Union's PSP port. It belonged to No. 367. It granted her Heavy Counter % Up, which would occasionally cause her counterattack to inflict fatal damage.
