You're looking at over 100 runs, (assuming you get unlucky with the 3% drop rate augments in Castrum bosses).
You can skip the coin req and get the upgrade material items from chests after the second boss if you saved enough prisoners. The drop rate isn't that low as well. Quite a few people have upgrade materials already and it's only day 2.
