Tap Mantle

( Complete Psionic, p. 58)

[Psionic]

You gain the ability to access the powers in a new mantle.

Prerequisite

Access to one psionic mantle,

Benefit

Whenever you gain the ability to learn another psionic power, you can choose a power you can manifest from this new mantle. You essentially gain a new menu of options from which you can select powers whenever you would normally learn a new power from advancing in a psionic class. You do not gain the mantle's granted ability or any other benefit of access to the mantle.

Special

You can gain this feat multiple times. Each time you do, you choose a new mantle to access.
