You can use another's psionic powers for yourself. You make a melee touch attack against a target. If successful, you immediately become familiar with the target's known powers, if any, and can choose a number of these powers to â€œleechâ€ equal to your Wisdom bonus (minimum one).
While the power lasts, you are treated as if you know the leeched powers. During this same period, the target of your power is locked out of those powers and can make no use of them. When the duration expires, you lose access to the leeched powers and the target regains immediate use of them. The relapse occurs regardless of the distance between you and the target. If you extend the duration of leech known power (or attempt to make it permanent), the original target gains a Will saving throw every 10 minutes beyond the original duration. If the target succeeds, the power's duration ends. If something kills the target before the duration lapses, you immediately lose the powers.
You cannot take a power that is beyond your level to manifest or that is not on your power list (such as an exclusive psychic warrior power or a power on a discipline select list that is not your primary discipline).
For every 1 additional power point you spend, the duration lasts one additional minute.
