I did this in one of the first boss fights while rescuing the Druid in early game. I pushed an underling off a ledge into the Giant Spider pit which kited them into the battle and drew the bosses agro allowing me time to finish off most of the underlings before focus firing.
That was a fun fight.
That gives me an idea for a necromancer who has a “staff” that is really a shovel for unearthing his servitors.
