From D&D Wiki
|This material is published under the OGL|
Manifester: This kind of weapon generates 5 power points once per day that the wearer can use when manifesting a power he knows. These power points must all be used on the same power. As usual, a psionic character cannot pay a power’s cost with power points from more than one source, so the power points in the shield must be used for discrete manifestations.
Moderate clairsentience; ML 8th; Craft Psionic Arms and Armor, knowledge of any 3rd-level power; Price +16,000 gp.
