The Overkill trophy is not being awarded. I have combined a diamond sword with smite IV and a potion of strength 2, and kill all variety of mobs using jump crits with no luck. I then had a second player on split screen load in with no armor, and was able to kill them in a single hit so I know I'm able to do at least 10 hearts of damage, but the trophy has still not popped.
