Micro-Servitor Manipulation System "Sandbag"

Description: A weapon created using information gleaned from data collected in the Samsonite Abyss. A combination of a large backpack container filled with lab modified "Sand" creatures and an arm mounted sonic device to control them. The Sand can act either as a mass of particles or form together into simple shapes. However, unlike the true sand of the Abyss, once it forms a hardened shape, it is stuck like that. 
WARNING: This system is somewhat limited in that it requires some form of light as well as an environment with sound in order to work. 
Special:
*Effective only in environments that allow the transference of sound.
*Requires exposure to minimum levels of light to remain active.
