You can craft psionic weapons and armour.
Prerequisite: Psionic Manifestation (3rd-Level)
Benefit: You can attune weapons and protective gear with up to a +5 enhancement bonus and a +5 equivalent in special abilities. Chapter 6: F/X contains a list of special arms/armour abilities, but that list is by no means exhaustive.
Crafting Psionic Armaments requires a Laboratory (see Chapter 1: Character Creation) and a mastercraft item to enchant. You can either make your own mastercraft item or attune an existing item. To attune an existing item, you must first acquire raw materials for the attuning process. The PDC = 19, and increases by 2 for every +1 enhancement (or equivalent). Thus a +1 item requires a Wealth check DC 21. The attuning process takes a half-day for every +1 enhancement bonus (or equivalent). If you attune a piece of armament with a special ability, you must have the psi-power associated with it and manifest that psi-power it as part of the attunement process. The appropriate psi-power is listed with the special ability description.
If you make your own item, add the time that it takes to make the item (see the Mastercraftskill) to the attuning time. Furthermore, the PDC for the raw materials is the PDC of the item, +2 for every +1 enhancement bonus (or equivalent).
Within any given seven-day period, the number of psionic items you can make is limited by the total levels’ worth of psi-powers in them. This includes cognizance crystals, dorjes, arms, and psi-stones. A 4th-level psi-power counts as four levels’ worth, for example, and weapon enhancements count as 1 spell level per +1 equivalent. You cannot create more levels worth of psi-powers in 7 days than your Constitution modifier x4. For example, if you have Constitution 18 (+4), then you cannot make more than 16 levels worth of items in one seven-day period.
