I play a lot of nemesis and i try a lot of combinaison and all of the very rare and ultra rare addon are not worth the cost. The only very rare addon that help you is the broken recovery coin 1 less supply case is helpful for your power but that all. What with the licker tongue that addon do nothing what is the hindered do i never saw a difference in the survivor gameplay when i use that.
On a positive not i believe the other addon are good and helpful specially if they can fix the zombie colision because them they get stuck a lot.
I just hope that the dev will check his addon in the next mid chapter patch i really think the killer is a solide mid tier killer with a good build.
