For 5 points and a force upgrade slot this upgrade gives a dark side force user a free aim token each time you take 1 or more damage. .
This card is a little odd - action economy is strong, and the more free actions you can get, like getting aim tokens, the better you will do - however this one comes at the cost of taking damage which is something you want to avoid. Especially if you are taking damage on the unit after you have activated and thus losing the ability to even use that aim token.
Because of the risk/reward and timing requirements on this card, as well as the restrictions of dark side force user for even equipping it, there is really only one unit who wants to take it at this point… Emperor Palpatine. On the turn that he uses And Now You Will Die the Anger upgrade card will add a ton of damage output to his attacks - this is the most reliable way to get use out of this card.
