Other appearances[]
Terra-Xehanort inherits this technique from Terra, and uses it during his boss battle. However, the speed and amounts of hits it can land are greatly increased through the power of darkness. He uses the attack frequently and repeatedly, often using it every time the player leaves himself open or tries to heal after being hit with the attack once. He is also capable of using the attack as a response to the player's attacks, interrupting the player in the process. If the Lingering Will uses Ars Solum on Terra-Xehanort, it is likely that Terra-Xehanort will simply respond in kind, interrupting the former's action.
Etymology[]
"Ars Solum" is a pun on the ability's original name "Solo Arcanum" ("First Secret" in Latin), and Last Arcanum's dub name of "Ars Arcanum" (roughly, "Secret Technique"). As such, it is meant to mean "First Technique".
"Ars" is the Latin word for "art or technique," and "Solum" is a Latin word which means "soil, bottom, or base," but "solum" can also be the Latin word for "alone."
