The Psychonic Blast is a special weapon of the game Star Trek: Armada which reduces the target's crew by a certain percentage of its current value. For the Romulans it is researched at the Tal Shiar Facility. It looks like this:

This weapon can come in two flavours, the variation used by the Romulan Shadow, that has a cool-down of 1 second and reduces the crew by 50%. And it is also used by the Entity, having a cool-down of 8 seconds and only reducing crew by 2%.

An active Corbomite Reflector has no effect on this special weapon. Neither does the Shield Remodulation. Psychonic Blast cannot target a ship using its Phase Cloak.
