If you have full power, use lilith or horus to remove immunity on Krampus. Then you can use an Eddie that gives negative effects to the enemy or use Iccarus power move twice followed by his normal move. Then use desert guardian normal move for the kill. I found 6 negative effects enough to kill Krampus. It may take a second round depending on your talis or relics.
