Triple Saber, known as Triple Impact (トリプルインパクト, Toripuru Inpakuto) in Japan, is a Special Move used by Xander Shakadera with his Xcalius X3 1 Iron and Xavier Bogard with his Xcalius X4 1' Sword and Xcalius X4 1'Dagger Sword.
Xcalius X3 1 Iron shifts its position twice to line up the two metal swords with the point on the 1 Forge Disc, for a three-point ultimate attack. It more powerful than Dual Sabers and it's similar how they shift the position to align the layer and Disc.
With Xcalius X4 1' Sword, Xavier puts Xcalius X4 in Buster Mode making the sword on the layer to extend out making it a longer sword. While in Buster Mode, Xcalius X4's center of gravity is off balance and has less stamina.
