Q: Dear Sage
Can a creature augment its psi-like abilities?
A: Not exactly.
Since a creature doesn’t pay power points to manifest a psi-like ability, it can’t spend extra power points to augment it (even if the creature has a power point reserve).
However, when a creature manifests a psi-like ability, "the power is manifested as if the creature had spent a number of power points equal to its manifester level, which may augment the power (Expanded Psionics Handbook 184).
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.
