Yes, it is that save. I used the ring, good thinking with met. axe
. I just got it from Debir's tower. That brings the int. to 94 with Depth of thought scroll, see screenshot. Bit of shame with those 6 fruits there, but at least people know now that playing with that save it is possible to get to 94 + 6 = 100 intellect. With sandals of martyr & snake ring (which I have not seen in this game) it will go to 103, and with a bit of luck with intellect shrines in some other playthrough it may go to 105!
