If you’ve been stuck searching for the Grand Central Theater Key in The First Berserker Khazan, then we will show you exactly where to find it in this guide. While most quests follow a linear path, some require puzzle-solving or tracking down keys to unlock new areas.
Where is the Grand Central Theater Key in The First Berserker Khazan?

The Grand Central Theater Key is located inside a chest beneath the gate area. However, when you first go downstairs using the nearby stairs, you’ll find the gate locked from the other side. To reach the chest, you’ll need to take a different route:
- Return to the floor where the Grand Central Theater gate is located.
- Look to your right—you’ll see a group of enemies near an open window.
- Defeat the enemies, then approach the window ledge.
- Adjust your camera to the right—you’ll notice a narrow ledge leading to another section of the museum.

NOTE: This path in The First Berserker Khazan is easy to miss and may be overlooked by a lot of players, so don’t waste time running in circles; just come to the window.
- Drop down onto the ledge, defeat any enemies in your way, and enter the corridor with multiple side rooms.
- Follow the connecting hallway until you find a chest near a mage enemy.
- Open the chest to claim the Grand Central Theater Key in The First Berserker Khazan.

Now, head back to the main corridor and unlock the previously blocked door (the one you saw earlier when descending the stairs).
Finally, take the stairs back up and use the key to progress forward in the Strange Melody mission of The First Berserker Khazan.

Missable Items To Gather Before Moving Past the Grand Central Theater Gate
As you collect the Grand Central Theater key from the chest, there are a few handful of things you should do before moving forward.
For starters, the room right from the chest contains a Soulstone. Make sure to break it before advancing ahead.
There is a Plague Cleanse Potion item as well under a statue guarded by an enemy. Make sure to grab it as well after dealing with the enemy first, which will likely drop Dragonknight's Helm, Chaos Cleanse Potion, and a few Transmutation Shards.
These things can be missed if you rush after opening the Grand Central Theater door only.
What Can You Find After the Grand Central Theater Gate in The First Berserker Khazan?
Once you get past the Grand Central Theater Gate, you will immediately find yourself in combat with an elite enemy. After you have beaten the elite enemy, continue pressing forward at the end of the hallway, and you will find a bigger gate, with Princess Ilyna as the main boss of this mission in the game.
Princess Ilyna deals Chaos status effect damage, so the Chaos Cleanse Potion you found earlier, while finding the Grand Central Theater key, will come in use here.
That is everything you need to know about where to find and get the Grand Central Theater key in The First Berserker Khazan. For more tips about the game, we recommend you check out our Best Greatsword Build and the Best Dual-Wield Build guides, here on Pro Game Guides.
