That's even if she gets to use her magic. Those monsters aren't exactly gonna give her a chance to draw the symbols and the lines from the symbols to each weapon. It'd probably take two... maybe three rounds with this whole 'circuit' thing she is trying to set up. 

Did I mention that magic isn't exactly a combative art in this world at this time XD

Its for more practical uses (lots of practical uses that can include opening doors, moving fire, stirring winds, moving distant objects that you can see, and other such things). Its an art of knowledge, not of power. 

Sorcery has more combat use, but it also drains a bit more energy and sometimes Vitality depending upon what you are trying to do. 

Also on Keia's comment on necromancy and summoning... those things may or may not exist already, but not necessarily as magic. (sure as hell doesn't mean it couldn't be done with magic)
