Getting rid of enemy mobs with your favorite character class in Diablo 4 will put your build's skills to the test to prevent them from overwhelming you. Necromancers have an advantage in that they can cover big areas of the map with their Minions, but even they can get too close to the action. Making use of the Bone Prison skill, Necromancers can trap and momentarily stop enemies and even apply status effects that will be detrimental to the enemies trapped inside.
