Do you forge Leadership or Leadership Boost?

Leadership Boost will upgrade 11 and Leadership will upgrade 21. Is there a difference?

You mean which one upgrade at the Blacksmith having 2 same leadership bonuses? Well they are the same things, so it’s preferable upgrade the one that can give you more leadership.

I just wasn’t sure if the leadership boost had a hidden talent to boost leadership even more

Both are same , upgrade one with higher value, leadership boost increases the speed with which morale charges in battle and leadership does the same lol
