Push affects the space in front of the user, and as such does not require a target to be evoked.
It is useless without one though.
it will move them back a short distance, and interrupt any arts currently being evoked.
It does not deal any damage.
Decreased evoke time.
Although it is available at orbit 0, Push must be learnt from a teacher, as opposed to other orbit 0 arts which are already known the first time the dreamer enters the city.
