Just to make sure, if I choose the Duration insight, I could decide to play the battle "forever" until one of the army is dead, right?
*hehe this would be great...endless battles...
but I will highlight the key words, ok?!
"Duration - This Insight automatically Activates during the Insight Activation step of the first Battle Turn. Increase or decrease the duration of the Battle by 1 Turn."
...and not during every battle turn
So only 1 adaption is allowed in total and this has to be done in the 1st battle turn insight activation step.
