Leader´s may appear when an elite army (or grnadmaster, in case of Japan´s medieval) whin a battle. Here, three questions: Is it possible to gain a leader with an amphibious assault? and what kind of building´s can you hurry?? In play the world you could hurry any improvment or wonder, and I THINK in this expansion you cannot hurry great wonders... Is that so? And, lastly, when an elite army wins and gain a leader, it may turn into an even better unit (in wich case you are given the option to rename it), but, this unit can yet produce leaders by winning? and can it evolve even more? If so, is there a limit?

Im not sure if there is a limit, i know that the scientific leaders can hurry great wonders, so i would assume leaders can too, but im not sure if they can use naval units. i dont know about how much the renamed warrior can evolve mine usually die two battles after they r specialized

Well, i know that military leader cannot hurry great wonders. The unit that is elite, renamed, and that produced a leader cannot go any further that elite, and yes, he can be upgraded but he goes back down to veteran for it and keeps his name. I hope this amswers the majority of your questions
