Ars Solum

Ars Solum (ソロアルカナム) is an Attack Command that can be used by Terra in Kingdom Hearts Birth by Sleep. It is a multi-hit combo similar to Ars Arcanum that can add up to three additional hits if one presses when the on-screen prompts appear. Being a possessed version of Terra, Terra-Xehanort can also use a version of this Deck Command, granted he increases the speed and amounts of hits it can land as well through the power of darkness. Its maximum level is 6, and its reload time is 25 seconds.

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". It is also an anagram for the words "Soul's Arm" although it is unlikely this was intentional.
