For 5 points and a force upgrade slot this upgrade gives a dark side force user the ability to scalpel out specific miniatures from a unit.
One wound in exchange for 5 points and a force upgrade slot seems like a bad deal, but when used right it can be a game changer. Because Choke lets you select the specific mini, not just the unit, you are able to kill key pieces making the trade much more in your favor.
With the release of Specialist Pack and weapon specialists weapons becoming the back bone of more and more lists, the ability to scalpel out these figures becomes more and more valuable. You are able to remove a special weapon or specialist upgrade mini such as comms or medic - and in multi-wound units you are able to dictate which figure has to have wounds allocated to it, for example you can force choke an Electrostaff Guard or Wookiee Bowcaster and then the controlling player is forced to allocate future wounds to that figure until it is defeated because of how wound allocation works. Making this upgrade useful and ever increasing in value as more and more unit additions are added.
