Some obvious improvements over my ESA practice run: I let the cavalry move on their own towards the town, and I built two monasteries instead of just one.

Anyway, this is pretty good. The right monastery is preferred since the relics are dumped on the top after destroying it, rather than on the bottom with the left monastery. I managed to get all three deposited relics into the right one fairly well, which is nice. There was some bad movement with the monks at the end as well, but otherwise this is a good run.
