Ah, I have that with My version of Cecilia's 2nd shift. Blue Tears Glas Hart.
The one off ability I call Nineveh's wisdom. It links Cecilia's brain with the IS core's processor as well as a separate system. This allows Cecilia to control all her bits as if it were a part of her body as well as push her calculation and comprehension ability beyond even superhuman standards granting foresight almost approaching clairvoyance. Basically her brain processes become better than even Tabane's in that time frame. However seeing things in that light cause some form of feeling of omnipotence. Overuse of Nineveh's wisdom causes an addiction and in some cases, a backlash noted mostly by depression and loss of self-esteem.
There was also "Night" a one off ability for Cecilia I suggested to zero but I don't know if he uses it
