In Lightyear Frontier, you will need to craft a number of items, but you'll need to collect all the materials to make them first. One of the many collectible materials out in the world is Red Crystal; there is really only one place to find these in any number in your Lightyear Frontier mech. You will need to look around the Pine Heights, which is most likely the place you will come to first after the Meadows. But you will also need to do some upgrades first to get any.
