This is not a simple "ion beam splitter"
This prism will look in either direction to see if there is a detected enemy
It will only redirect the beam in the direction that an enemy is in
If there is an enemy on both sides, the beam will be divided between both directions.
You can also force which direction with a toggle button
This would allow for more creative ion setups such as an ion broadsider that can redirect its full power to a single side
