You can create psionic tattoos, which store powers within their designs.

Prerequisite: Manifester level 3rd.

Benefit: You can create a psionic tattoo of any power of 3rd level or lower that you know and that targets one or more creatures. Scribing a psionic tattoo takes one day. When you create a psionic tattoo, you set the manifester level. The manifester level must be sufficient to manifest the power in question and no higher than your own level. The base price of a psionic tattoo is its power level x its manifester level x 50 gp. To scribe a tattoo, you must use up raw materials (special inks, masterwork needles, and so on) costing one-half of this base price. When you create a psionic tattoo, you make any choices that you would normally make when manifesting the power. When its wearer physically activates the tattoo, the wearer is the target of the power.
