Star Crystal Shards

What is a Star Crystal Shard?
Star Crystal Shards (commonly abbreviated to as SCS) are crystals that have certain abilities that are unique to each crystal. SCS come in three forms:

Individual Crystals
These SCS are formed by the Starmans core or other influences that affect the Starman mental or physical state. These crystals once added to the core; can not be removed unlike the other SCS. SCS that form in individual crystals can't be destroyed or removed from a Starman unless their StarCore has been destroyed, and even then it's likely to not work perfectly right since the crystal was designed for that individuals body.

Gender Based Crystals
Similarly to Individual SCS, these crystals only work on Starmen of a certain sex, but they can be removed from the StarCore.

Any Crystal
These SCS are noted to not have any restrictions to stop the user from using it, but as a result they tend to be weaker than others SCS. Usually the SCS of this type are sold at shops or retrieved from the depths of the mines.
