Stage 7

Complete Stage 7 (Empty Halls Behind Locked Doors) in genshin impact Theater Mechanicus with no more than 20 escaped monsters.

Objective: No more than 20 escaped monsters.

Introduction: This stage is a little tougher because in the later waves, the enemies will start coming from three portals in two different directions. By bolstering up in front of your portal (Blue) first, makes it easier to hit them where both lanes converge, creating a chokepoint.
