For 5 points and a force upgrade slot this upgrade gives a light side force user the ability to dump suppression on a unit at range 1-2.
This card is incredibly powerful allowing you to panic a corps unit or suppress an elite unit who is outside of their commanders aura. Being a free action instead of costing you an attack action means that often you can put 3 suppression out in a turn which is quite powerful.
Because this card exhausts and light side has no current masters of the force, this card sees limited play. As soon as light side has a master of the force however I expect this card to make a huge return and to really influence the action economy of the game.
