Tekkers and me being lazy

[Sesshomaru]

from my understanding of the tekkers, you can change the type of the weapon......for example if the tekker said your Railgun was something like Heart.....well you can either keep the 'heart' on the railgun or spend some extra cash trying to get the tekker to change the 'heart' into a soul, or perhaps even a geist type weapon. It could cost you an upwards of about 10000 meseta if your really desparate for a good weapon. But, it overall gives your weapon a much better special ability.
