As you progress through the first Chapter in Beast of Reincarnation, you’re likely to come across a Red Key that unlocks a big, ornate door in Subcity 03. However, that’s not all; you’ll also need a Blue Key and a Yellow Key to open this massive bronze door.
The good news is that these keys are pretty easy to find, and once you have all 3 in your possession (and don’t forget to unlock the wooden door in the Abandoned Village), you’ll be able to progress to the end of Chapter 1. Here’s what you need to do to find the Blue and Yellow Keys in Beast of Reincarnation.
How to find the Blue Key in Beast of Reincarnation?

Before I explain the process, it’s important to keep in mind that you’ll first need to get your hands on the Red Key, we explain everything about the Red Key and the door in the Abandoned Village in another guide.
But in a nutshell, this one can be obtained by speaking to the Golem who’s right next to the entrance of Nushi’s Lair. Once you’re done chatting with him, he’ll hand over the Red Key. You will also receive markers on your screen, which will lead you to the remaining keys. All that’s left to do is follow the first marker, which is going to take you to the Blue Key.
You need to go to the north-eastern side of the map, where you will come across a campsite. Here, there’s a Golem with the Blue Key lying right in front of him. Keep in mind that this campsite sits on top of a cliff, and to reach it, you’ll need to make use of Emma’s hair to climb up.
To make things easier for you, I have marked the exact location of this campsite in the image above. The key emits a glowing purple aura, which makes it quite easy to spot. Once you have spotted it, simply go ahead and interact with it to pick it up.
How to use the Blue Key in Beast of Reincarnation

Like the Red Key, the Blue Key’s main purpose is to help you unlock the big ornate door I talked about at the start of the guide. However, you’ll also need the Yellow Key before you can open the entrance.
To obtain the Yellow Key in Beast of Reincarnation, what you’re going to need to do is fight the Grizzly Malefact that can be found in the Tailwater Village. Once you’ve done that, you will receive the Tailwater Key. Continue through the same cave until you come across a locked door, and then use the Tailwater Key to open it. Inside here, you will find another Golem who will hand you the Yellow Key.
There’s another secret use of the Blue Key. At the location I’ve shown in the image above, there’s a locked storage door that can only be opened with the Blue Key. There isn’t anything particularly special waiting behind this one, but you’ll find some useful loot inside it. Don’t miss out on it, as every resource is worth picking up during your journey in these lands.
