The Matter Cannon is a weapon added by Applied Energistics. It fires Nuggets and Matter Balls as ammunition, with heavier materials doing more damage.
The Matter Cannon must be loaded and charged before use. When loading, the Matter Cannon behaves like a pre-formatted Storage Cell, only accepting items that can be used as ammunition. It can be charged in an ME Power Relay, or any other compatible charging block (e.g. an Industrial Craft 2 MFE or Thermal Expansion Energetic Infuser).
The matter cannon will take any metal Nugget (e.g. Lead Nuggets) or matter balls as ammunition. Not all Nuggets will count as ammunition (e.g. Meat Nuggets). Damage is variable depending on how heavy the metal would be in real life.
An powered melee weapon based on the power of Charged Certus Quartz Crystal, it only has a few uses but it can be an effective rechargeable weapon, it must be re-charged in the Charger when its power is depleted.
The Charged Staff Holds 8k ae in its battery using 300 ae per attack.
