I have used him with iggy. You can give him burning 4 I also like to send him to the target of the hem. I like nekima for hem if you can get it. You give the doll burning 4 and go over to nekima in combat. The burning is given to nekima and when she takes that damage you start the black blood engine. Which will make an infinent loop. You only get a max of 6 damage if you don't get the black blood going befor burning but, if you get it befor burning you get 10. Not to bad.
