The disintegrator fires a small particle of dark matter in much the same way that an Imperial plasma cannon fires super-heated plasma. It is, however, a much more sophisticated weapon and can be set to either fire a large bolt, or a burst of smaller shots. Before firing the disintegrator declare if you're firing it on maximal (one big shot) or sustained (several smaller shots). The attacks have the following profiles:
Maximal = Rng 36", S7, AP2, heavy 1 blast Sustained = Rng 24", S4, AP3, heavy 3.
