It’s only a 90% chance of getting ntg with a 5* victory. There’s some debate if that 90% is actually correct or not but with the few university buffs to ntgs like the one for marble in devinci it says it boosts it 10% once all levels completed. This would mean 90+10=100% chance with 5*. So I’m working on finishing the devinci upgrade to test out if this works or not. Hopefully it does. Then all we need is for every ntg to be put into the university in the same manner. I think only marble, tea, and scroll chances are currently in the uni.
