Word magic was simple. One just had to write something in the air with mana, and the mana would become that something. For example, if the caster writes Fire Arrow, the words will become a Fire Arrow after a few seconds and then fly toward the target. Although in the beginning, the caster has to waste a lot of time to cast a single spell, it gets better late because the users can obtain all kinds of effects by using word magic. For example, the caster could write the words: Fast Conjuration, and the caster would be able to write faster than before. As if that wasn't amazing enough, the more mana one uses when writing, the more powerful the effects can become. The best example was what Hannah could do with a single fire arrow; she actually could destroy a five meters tall building.
