Inferno tactics.

Therefore, to gather 100 demons, 15 pits would be enough, provided there are some hiding places and secondary locations, preferably rampart-style. And if there are 70 pits, the mechanical increase in demons will definitely result in more than 100. Besides, 100 demons in terms of attack power cannot be compared to 70 pits.
P.S. + you can also stand on the corpse of a demon and say hello =)
