Turn Grunt Birthday Party (to get multiple kills), Catch, Black Eye (on the first level), Iron (put this one on easy), Fog, and the one where the enemies get double health (when covinent are on your team and there's no brutes). Easiest combination of skulls Grunt Birthday Party, Iron, Fog, and Mythic.
