A Psionic Focus Crystal is a crystal that's been tuned by a Psion for future use. One can only be made by a Psion with a Psionic Strength of 9 or higher (a Stage 4 Psion). The Psion can take a normal crystal and tune it for a number of days equal to their Psionic Strength DM, paying Psi Points equal to their Psionic Strength DM each day, and the crystal can then be used as a Psionic Focus Crystal. Thereafter, once per day, the crystal can be used either to provide a bonus to one psionic skill roll equal to the tuning Psion's Psionic Strength DM, or, to provide spendable Psi Points equal to the tuning Psion's Psionic Strength DM. But not both. The effects can be used by any Psion. A Psionic Focus Crystal will start to take on the properties of the Psionic Talent it is used the most for - but there's no hard and fast way to tune the crystal for this. A Psionic Focus Crystal can be given to another person as an heirloom or gift, and some have found their way to the black market.
The most famous officially known Psionic Focus Crystal was The Boonto - the Psionic Focus Crystal of Felix Ches'de'fijak, a powerful Psion from before the Psionic Suppressions. It can be found at the Sylean Museum of History on Capital. It has a Psionic Strength of +2 and is said to cause Premonitions. The Boonto has been stolen several times, only to be returned anonymously each time.
There are rumors of a Psionic Focus Crystal so powerful and ancient that it also has the power to heal or bring someone back from the dead.
The Psionic Focus Crystal is an organic way of creating both a Psi Enhancer and a limited Personal Psi Battery.
