The executioner figure upgrade from the infantry command indicates that on a skill icon you "choose a wounded figure in an enemy engaged with you and remove it." http://runewars.wikia.com/wiki/Executioner
Originally I had thought that this meant you could wound Kari, then use the skill to remove her, insta-kill. You could also do this with the Rune Golems, wound them then insta-kill them. That seems rather strong for the unit's cost and leads me to believe this is supposed to work only on figure upgrades within a unit, rather than on any figure. I've been going through the rules reference and can't find anything to confirm this. Section 38 references figure upgrades, but the card does not specify figure upgrades, just figures. section 87 describes a "unit" and uses the same word "figure" to describe the individual miniatures that go into each tray, which bring me back to my original thought of how this works. I would love to hear how I am interpreting this wrong and missing a key rule, I just can't find rules to back it up currently. Maybe I am right and you can insta-kill Kari with a white modifier? I mean at that point, line up a move action that will engage a wounded Kari or Rune Golem, collide with them and get a panic token, but then use the white modifier to kill them. Very much worth the panic token.
