"Effective Against Armor"

[caravel]

That was very interesting, as many posts here.

I have two questions though

1/ When we consider the stats of a unit. What does the armor do? does it stacks wis the defence stat, or does it give some "saving throw" to a man stricken to death, like "if I'm dead and I have a 4 armour bonus I have 50% of staying alive"?

Armour is a separate stat to defence. Armour is all about protecting against a successful hit from an opponent's weapon or missile, wheras defense is all about evading the hit in the first place IIRC. Armour has better protection against missiles, though units that are armoured will tire more quickly in the desert.

2/ speaking of this, clearly a weapon upgrade gives a +1 attack. But what does give an armor upgrade? +1 defence due to armor, or +1 defense AND +1 armor (them stacking, or giving at the same time a better defence stat and a better chance of avoiding death while effectively hit)

Armour upgrades (Armourer) give +1 armour. Weapon upgrades (Metalsmith) give +1 attack. Neither give valour bonuses at master level.

And two very simple and technical questions (I hope this is not to bad a behavior...):
1/ what does the F1 key do? Do we have acces to actual figures, instead of "good attack", "poor defense" and the like?

It shows the unit stats for the units on the battlefield. You will see the actual stats, including morale, of those units while they are in battle. This may change completely once you get back to the campaign map.

2/ Is it possible to build battles choosing the units to train oneself? I read stuff about people making some very precise testing on some very specific units?

Thanks!

Custom battles are the way to do that.
