I also checked my system to see if there was special spy training for my minion, but there wasn't any special spy training for the minion. I will have to send scouts to find out more about the enemies. I also have the option to train warrior minions to Stage 1 of the Intelligence Variant. This will make them more suitable for spying on enemies.
I thought about it for a while, and this was the best idea I was able to come up with. So, I opened my control system.
