Biome 4-6 key finding
Is it me or in biomes 4-6, there are just a lot of key finding. In biomes 4, you needed 2 keys to open the echoing vault. In 5, you needed 3 keys to open up the hadal vault and then in 6, you needed 1 to open up the abyssal vault.
Could they really not think of a different objective, like biome 1-3?
