In Rarity Miner, Lost keys are required to unlock Key Chests, which ultimately reward you with various useful resources and items. However, finding a Lost Key is a daunting task due to its limited availability and fixed spawn location, so I’ve put together this guide to help you find it in Rarity Miner.
How to find Lost Keys in Rarity Miner
Lost keys can typically be found in caves at depths between 440m and 1,000mspecifically in the biomes of Basalt to Tuff. You usually find three or four keys in a cave, and they are relatively easy to spot in Rarity Miner. For example, I found one of the Lost Keys 700 meters below the surface.
However, it is worth noting that their spawn locations are not fixed, which means that you will randomly encounter them during your exploration. Once you collect a Lost Key, it will be added to your inventory and the Cave Index will also be updated so you don’t have to remember its exact depth.
What is the Lost Key used for in Rarity Miner?
As mentioned before, Lost Keys can unlock the Lost Chests in Rarity Miners, which contain useful rewards. Unfortunately, finding these chests is a difficult task just as they appear Cave of Shine. So far, I haven’t received anything of value from them but I was lucky enough to get a Celestial from one of the chests. So, it’s safe to assume that the rewards are random, and the rarity you get is just a matter of luck.
Honestly, I don’t think investing your precious time to find Lost Keys and Chests is worth it. I would recommend focusing on your regular farming techniques rather than relying on chests for rewards.
