You are able to store ki energy within glowing crystals.
Benefit(s): You can imbue a carved stone or crystal with 1 ki point for later use. This requires a crystal or gemstone worth at least 100 gp. You must spend 8 hours meditating and perfecting the crystal, expending 2 points from your ki pool and making a DC 20 Craft (gem cutting) check. If the check succeeds, you store 1 point of ki in the crystal for a number of days equal to your Wisdom modifier. The crystal glows like a candle until the ki within is expended. If the check fails, no ki is absorbed. If the check fails by 5 or more, or if you roll a natural 1, the crystal shatters.
Transferring 1 ki point from a ki crystal into a creature’s ki pool requires a full-round action (which does not provoke attacks of opportunity) and a DC 10 Wisdom check if the crystal is held in one hand, DC 15 if it is carried or worn; ki crystals in extradimensional spaces cannot be accessed. This DC increases by 2 for each ki crystal after the first tapped by a creature during a 24-hour period.
Ki points stored in ki crystals are not considered part of the bearer’s ki pool, and a creature must have a ki pool (even a temporary ki pool, as provided by Endow Ki) in order to transfer and use the stored ki. Once the stored ki is transferred from the crystal, the ki crystal’s inner light fades. Replenishing the ki in an existing ki crystal requires 1 hour and the expenditure of 2 additional ki points but no additional cash expenditure.
