Users of this ability are more intelligent than their species, or at least able to use their brain more efficiently either by being naturally gifted or training themselves for the needed shortcuts. Some are able to perform feats of mind comparable to computers: remembering vast amounts of knowledge flawlessly, performing complex calculations or other similar tasks. Some are capable of learning a variety of combat skills in a day, which would take a normal person years to achieve mastery over.
Users are glaringly, obviously and super/unnaturally more intelligent than their race because their capabilities are pushed to the superhuman level; making them immensely smarter than any level normal members of their species (in that 'verse) can achieve by any method of training.
The users intellectual faculties (memory, calculation, learning, creativity, etc) transcend virtually all other sentient beings in the universe. In the time it takes others to frame any word or comment, the character can think thoughts equal in volume to every book and file written by every human being from the dawn of history to the present, each second containing a billion more thoughts, reflections, and experiences than an entire lifetime.
All aspects of their intelligence are infinite, but inferior to Nigh-Omniscience and Total Omniscience. This power differs from Omniscience in that the user has, essentially, a limitless IQ and intellectual capacity, rather than having innate knowledge of everything. This is the greatest, most supreme level of intellect a being can attain.Â
