I'll speed run past the parts that aren't part of the strike and don't affect the strike at all. Prime examples are the room right after the 3 wave stage in phogoth and all the enemies in the circle of bones after. Or the beginning room of the rockets mcdickface strike with the two colossus before you reach the lieutenants. The issue here would be if you have a black hammer and it's a boss like archon priest or phogoth, everybody should protect you as you drop the hammer. Easiest and fastest way to do it. Don't mess up their critical hits just kill the adds around
