Q: Dear Sage,
Can I use the Expanded Knowledge feat (Expanded Psionics Handbook, 46) to select a power from another class’s list if it’s also on my class’s list at a different level?
You’d manifest the power at the selected level, not the normal level for your class.
For example, if a 5th-level psion used Expanded Knowledge to select body adjustment from the 2nd-level list of psychic warrior powers, he’d manifest it as a 2nd-level power, paying 3 power points to do so.
About the Author
The Sage is a mammal classified in the bear family, Ursidae, native to central and southern China. Debate continues as to whether he is truly a bear or more related to the raccoon rather than the bear, or perhaps in a family of his own. When not eating bamboo and answering rules questions, he works under the nom de plume of Andy Collins as an RPG developer in Wizards of the Coast R&D, where his development credits include Complete Mage, Dragon Magic, and the Player's Handbook v.3.5. He can be easily recognized by his large, distinctive black patches around the eyes, ears and on his rotund body.
