Just telling you, my zFinn is G12 +4 and my zRey Scav I'd g11. I couldn't figure out for the life of me how to do tier 6. I finally saw a YouTube vid and was like, "Oh, my Finn has to die" so I had to in Mod him. Your event's Kylo could not kill him even when I just used basic.

Edit- ok, so I just set auto battle to basic only and Finn died after a while. So Kylo can kill Finn if he doesn't use his kit.
