A Single Source: When using
power points from a storage item to manifest a power, a
psionic character may not pay the power's cost with
power points from more than one source. He must either use an item, his own
power point reserve, or some other discrete
power point source to pay the manifestation cost.
Recharging: Most
power point storage devices allow
psionic characters to "recharge" the item with their own
power points. Doing this depletes the character's
power point reserve on a 1-for-1 basis as if he had manifested a power; however, those
power points remain indefinitely stored. The opposite is not true-
psionic characters may not use
power points stored in a storage item to replenish their own
power point reserves.
