How To Farm Crystal Keys
In Pet Simulator 99, you can farm Crystal Keys by purchasing the two parts of the key from the Merchant, the Advance Merchant and the Travelling Merchant in exchange for Diamonds.
For players who don't know, the Crystal Key in Pet Simulator 99 has two halves, the lower and upper half, and you must combine them to form the complete Crystal Key.
The best part about purchasing the Crystal Keys from Merchants is that once you clear their inventory, after a few minutes, they will restock after 15 to 20 minutes or so, making it one of the best ways to farm Crystal Keys.
That being said, while you are at it, purchasing the key parts from Merchants, we also recommend collecting your Free Items in the starting area as they also drop the Crystal Key parts.
Where To Find Merchant, Travelling Merchant & Advance Merchant
You can find the Travelling Merchant in Area 5 - Autumn, the Merchant in Area 19 - Oasis and lastly, the Advance Merchant in Area 39 - Ice Rink.
