Lightyear Frontier is an alien world filled to the brim with weird plants, animals, minerals, metals, and more. This beautiful farming sim game holds a collection of everything you'll need to upgrade, build, and maintain your new home planet. One of the many materials that need to be farmed for is something called a Blue Crystal. You won't need these early game, but finding them will become incredibly important around the middle point of the game. In order to make sure you have enough to go around to all of your builds, you'll need to head into the Yellow Forest to find Blue Crystals in any amount.

Where to Find Blue Crystal in Lightyear Frontier

Blue Crystal can be found in two main locations in your Lightyear Frontier mech: the Yellow Forest and the Lowland Plains. The easiest place to get to it and farm it daily is the Yellow Forest, in the place the orange marker is on the map above. You can find these Crystals in little clumps along this rocky part of the Forest; they are usually a bunch of clusters around the edges of where the Forest meets the Meadows. Here is a screenshot of what these Blue Crystals will look like when you find them in the game:

How Often Does Blue Crystal Respawn in Lightyear Frontier?

If you have cleared out the Yellow Forest of all of its Blue Crystal, you might be wondering when you will see it pop up again. Some of the Crystals will respawn the next day, and most of it will be back after two days. The third in-game day will most likely bring back all of it, and you will have a whole new crop of Blue Crystals to saw. Sleeping is the best way to pass the time in Lightyear Frontier, so make sure build a tent early. A great tip for those new to Lightyear Frontier is to find a place to farm all materials every three days or so, rotating which materia you farm every day.
