Context: Our warlock has become king of Gnolls and was given the ability to summon a small army of 10 Gnolls once a session if they roll a nat 20. The Party was fighting a group of assassins.=
Warlock: Oh I just remembered I can summon an army. Should I try?
Monk and Blood Hunter: YES!!?
DM: Make a nat 20 attempt
Warlock: NATCH-URAL 20 BOOOOOYS
DM: Shit…. ok so almost out of nowhere a group of Gnolls breaks in through the windows, they fall out of the roof, and even climb out of the floor and pose like the Ginyu Force around their king.
Warlock: Get fucked my dudes!
