Well, the heroes and units on the map are sort-of regular. There is a bunch of selectable heroes with switched abilities. I imagine the original Warchasers would be somewhat comparable. Of course, there will be custom boss units/Heroes with some harsh pepper, both stat- and ability-wise. Also, I planned for a single player map. Nothing multi.
Weak standard units would be be pounded or outright killed by a standard mine, but larger standard units would be less damaged. The standard mine deals 700 damage, as far as I remember, so I suppose that could theoretically be the base output for a level 3 mine, where level 1 and 2 were somewhat lesser. Like 1/3 and 2/3 or whatever. 700 just seems like a lot for a non-Ultimate skill. To me, at least. As for detection, I guess some would be able to see them. I haven't really decided on how many True Sighters I'm gonna add to the enemies yet.
