IAIDO
(note: definitely NOT doing this one)

This would give a character the Iaido (Draw Out) command from the Samurai class in Final Fantasy tactics. The command would check for the equipped weapon. If it was SwdTech enabled, it would check it against an index of spells and cast the spell associated with the weapon. For example, the Kazekiri/Tempest would cast Wind Slash, whereas the Mutsunomaki/Sky Render would cast Flare Star.

Or you could just change Edgars tools into samurai swords and it would work exactly like it did in the game without the chance of weapon break.
