During Witchspire‘s Level 13 Main Quest, Notes From Underground, your objective is to ‘locate the key in the subterranean cave‘. The key won’t be sitting nearby, and its location isn’t marked on the map—so you’ll have to roam around the Timberline Basin area to find it.
That said, it can be tough to know where to begin if you’re not sure what to look for. For that reason, this page lays out exactly where to discover the key in the underground of Witchspire, so you can push your quest forward.
Where to find the key in the underground cave in Witchspire
In this Level 13 Main Quest, Notes From Underground in Witchspire, you’ll step into an Al’uunian Tower that holds a chest, a portal, and a note saying that your friend found a key and then hid it underground. After that, you’re told to ‘find a key in the subterranean cave’.
If you go through the portal in this room (shown below), you’ll reach an area below—though it isn’t a cave. Instead, you’ll come across a beach with Bompus creatures, along with the lower part of the Timberline Basin region. From there, you’ll need to search the surrounding spots to uncover the hidden cave and the key inside it.
After you step out of the portal, head to the right. You’ll run into a few Xilvant’s along the way, and you’ll eventually reach a cavern you can jump into. Once you’re at the bottom, you’ll be in Shard Caverns, surrounded by a number of Shardlings.
Now that you’re in Shard Caverns, you’ll need to dodge the cranky Shardlings and continue on to the main chamber. In this area, you must quickly activate all three pedestals to open the door ahead. You’ll also find a few chests here that you can loot!
After you leave the central chamber, you’ll enter The Vagabond’s Lair, where a lone Shudder waits. Don’t run past him—you have to defeat him, because he’s the one who drops the key you need. That’s why this hidden key is so easy to miss.
Once you’ve defeated the Shudder and picked up the key, it’s time to return to Witchspire and put it to use. To get out of the cave, activate the pedestal positioned behind the Shudder to open the next door, then bounce around on the jellyfish in the area ahead. They’ll guide you right back out of the cave.
Good luck grabbing the key from the underground cave and continuing your adventure in Witchspire. If you want more help, take a look at my tips and tricks to help you get the most out of the game—including where to find Copper Ingots and how to obtain new Familiars.
