"A slow yet powerful charge weapon. Causes devastating damage to target."
The Ion Cannon is a powerful weapon that takes a singificant amount of time to charge and consumes an Ion Core for each volley. The Ion Cannon is available for construction on Level 10 starships.
Each level of the Ion Core deals a greater damage to crew than it does to hull and systems, making the Ion Cannon an effective weapon for clearing out support crew, provided that it is not countered by the Shield.
Due to the long recharge time, using the Rush Command ability on this room provides excellent value.
