The Light Crystal is one of the four crystals hidden throughout the environment as of Alpha 0.0.9e. It is also known as the Protection crystal. It is a bright yellow in color, and it's vibrancy is greater than the other crystals.
The Light Crystal is found in the stone church which is found across the bridge due right from the Blacksmith Shop and Parts Shop. This crystal is initially labelled as "Crystal (Unknown)" but is revealed upon touching it that it is the "Light Crystal (Protection)" and it also produces an effect around your screen.Not much is yet known about these crystals but it is confirmed that there will be some higher use for them other than being aesthetically pleasing.
Interacting with the CrystalEdit
Nearing the crystal, it's labeled as Crystal (Unknown) until you pick it up, similar to the Dark Crystal. Once you do pick it up, the Protection effect emanates from the crystal in a large radius while held. After dropping the crystal, it is now labeled as Light Crystal (Protection) and ceases to emit it's Protection effect. (The effect hasn't changed from 0.0.82 to 0.0.9e therefore this image is still valid)
