Arc of Time

Arc of Time (時間のアーク Toki no Āku) is a form of Lost Magic that involves the usage of time as a means of combat.

Description
Ultear's branch of specialty is to manipulate the "time" of an object or a living thing but not a human. She can fast forward an object's "time" into the future, making it decay rapidly or rush to attack her opponent. She can even stop an object's "time" by freezing it in midair. She can also rewind a damaged object's "time" to restore it to its original state. She can produce 'bubbles' of time that show the various potential things that the item could do and then pick one of the timelines whenever she wants to. Ultear learnt this magic that was said to defeat molding magic mages to kill her mother, Ur. After the time skip, Ultear seems to be able to use this magic to affect humans to a degree by using it to evolve Mages' containers of Magic Power so that they're capable to use Second Origin
