A spectral savant can make a touch attack once per round and drain a number of power points from a living psionic character or creature, equal to its HD or lower. For creatures that possess only psilike abilities, the spectral savant drains one use of the highestlevel ability available to that creature, gaining a number of psionic power points appropriate to the ability plus any augmentations, based on the manifester level of the creature. For example, if a spectral savant were to drain the single use of mind thrust that a cerebrilith receives in a day, it would receive 9 power points, since the cerebrilith manifests that power at 9th level (normally requiring 9 power points to do so). If the number of power points that the spectral savant would receive exceeds its maximum(spectral savant's HD), the remaining power points are lost to the spectral savant. A ctral savant cannot attempt to draw more than its HD in power points in a single attack, from a creature that normally uses power points, simply to make them unavailable to that creature.
就是这么一段太长理解不能,其他都比较简单.
