I have been trying to think of a good use for this late game item, but nothing seems compelling enough to give up a larger volley.
The Quantum Capacitor
One idea I had is using it for warning shots against watchers and recyclers, but is the 1-3 extra turns you could move in the time saved really worth it? It doesn't really seem practical for combat unless you were dangerously low on weapons already.
Does anyone have other ideas?
