+12 waves if you clear the area almost instantly after a spawn.+8 waves if you kill all monsters quickly after a spawn.+6 waves if you kill all monsters on the battlefield.+3 waves if you kill most of the monsters.+2 waves if you kill a lot of freshly spawned monsters.Players can progress faster by defeating monsters quickly: Every few seconds, a new wave of monsters spawns.You are overwhelmed when there are about 10 waves of monsters out on the battlefield.The difficulty scales similarly to Greater Rift Levels as players progress throughout the waves.Monsters from the Echoing Nightmares do not drop gold, items or health globes.
