Power Jinxes make Wrench cry. As per the rules:
If Wrench has a Power Jinx from Natyli, then all of the numeric effects on all of his Gizmos are reduced by 1, but only during Wrench’s Action Phase. (This does not affect the numbers on the Gizmos’ Fortitude tracks.) Note that a Power Jinx causes many of Wrench’s Gizmos to temporarily do nothing - including his Passive Gizmos! Wrench returns his Power Jinx to Natyli after he has ticked down all of his Gizmos.
In short, this means that the all three (or more) of the Gizmos would have suffered the penalty. Normally this has no effect on his defensive Gizmos, but it does mean that Wrench is susceptible to hit-backs and Anytime Drinks during his Action Phase with a Power Jinx.
Many folks may flip the table and claim this is unfair cause it makes Power Jinx super good vs. Wrench. However, seeing as how all of Wrench's actions are pure value anyway, it's not THAT bad.
