You can construct and attach crystalics to willing entities.
Prerequisite: You can create any crystalic whose prerequisites you meet. Crafting a crystalic takes one day for each 1,000 gp in its base price. A creature may only have five crystalics on its form at any given time. To craft a crystalic, you must spend 1/25 of the item's base price in XP and use up raw materials costing one-half of this price.
You can also mend a broken crystalic if it is one that you could make. Doing so costs half the XP, half the raw materials, and half the time it would take to craft that crystalic in the first place.
Some crystalics incur extra costs in XP, as noted in their description. These costs are in addition to those derived from the item's base price. You must pay such a cost to create a crystalic or to mend a broken one.
