Magic Light

Magic Light (マジック・ライト) is a spell common to all Mage classes. They look almost identical to, but are not the same as, the Summoner-class summon spirit, Lumiere.

Description
A non-offensive spell that produces light at the end of the user's staff, which then forms into a floating, possibly-sentient orb of blue or yellow light that follows the caster. The orb of light will turn its head as its caster turns his or her head, and cower behind the caster when faced with opponents.

It is also shown to be capable of reflecting the caster's emotions, flaring up when Rudy was angry. It is also shown in "Expeditionary Force" that the caster is able to make the orb of light emit a beam of light towards a specific target.
