That was good size of an army. Bet he has spent some future or STEEM to build it up since I cant imagine that he has more weapon and alcohol production than many of the Viking members have.
The army he has now cost 88 million weapon and 84 million alcohol to build. If you have a production of 1 mill of each every day (I dont think he has so much) it will take 88 days to get that army size.
Good that you took out the Rowdys :)
