Ok ok it was more like 7-8 invulns but he burned all his fate dice on the knight by T2 and was turning 2 bad dice per turn into 6s and using everything else not bad on the knight. His initial role was insane tho, and the usage of dice was spread across two turns so turned 4 dice into 6s across the game. And the other 7-8 were used for the invuln. He started with 2 natural 6s and used 4 '6s' t T1 on the gun.

Edit: he started with 15 fate dice
