An upgrade to the third level? Interesting idea, although I almost never built the third level in this Castle, I took other Castles and stocked up on archers there.
But why not, as long as there's nothing to replace them with? They are quite suitable for the initial clearing...
Although there were other cases. Here, too, the starting units matter - if there are a couple of Orcs and a Jabberwock, it might turn out to be interesting.
He can be used as a starting hero; Orcs are always present, plus ranged attacks...
And also, by the way, revival on upgraded
wolves works well.
What did you mean by that?
