Other appearances
Terra-Xehanort inherits this technique from Terra, and uses it during his boss battle, though the speed of the three hit finisher is greatly increased through the power of darkness.

In his story battle in Kingdom Hearts III, his Ars Solum is comprised of only six hits and the fifth hit breaks guards. In his Data Battle, he has two variations. The first variant, a 12-hit combo, has him teleporting and performing the first three blows before teleporting again to perform the first three blows. Then after the second teleport, he performs the first three blows and two more blows before teleporting for the finishing blow. Whenever he teleports, his Keyblade glows red from the power of darkness and the first slash of the attack is unblockable. The second variation starts with him charging up and coating himself in a red aura of darkness. Then he teleports and performs the first three slashes, teleports and performs two slashes, teleports and performs a single slash and then performs the teleporting finisher twice. Then he charges up and coats himself in a red aura of darkness again, teleports and performs the first three blows, and teleports and performs three blows before teleporting for the last finisher. Each swing except the second to last is unblockable.

Etymology
"Ars Solum" is a pun on the ability's original name "Solo Arcanum" (roughly, "Only Secret" in Latin), and Last Arcanum's dub name of "Ars Arcanum" (roughly, "Secret Technique"). As such, it is meant to mean "First Technique". "Solum" can also be read as "ground" or "earth" in Latin, playing on Terra's own name; as such, "Ars Solum" can be read as "Earth Technique".
