Some questions (Man, precision and other)

[Beorne]

I'm a newbie and I'd like to understand more deeply the mechananics of this game.
How the precision stat of missile weapons interact with the target? the target rolls against def or what? And the precision of spells rolls against something to hit (apart the spell resistance if applicable)?
What is the precision loss due to diatance?

I take for now the Man - Last of the Tuhatas theme: I noted that my sacred infantry is blurring all the times during combat. I thought it was an air shield created by the blessing (i'm a nature-air pretender). But It appears that it is in even before the blessing. Are my units always air protected? If so, how do I know the additional benefits of spacial themes?
How air shield work? Is the miss percent is calculated after the missile hit?

Thank you

Tuathas and Sidhe have the Glamour ability, which grants the effects of the Mirror Image spell in combat. They are also completely undetectable by scouts and spies on the strategic map. This is not related to an Air blessing at all, as they have this ability even when not blessed.

Can't help with details, but the defense stat is irrelevant versus missile attacks.

But mirror images aren't, as I found out to my chagrin this morning while watching five storm demons continually miss a mirror imaged vampire queen while hitting her square multiple times.

As an aside, what is the damage from the shock portion of a thunder fist attack?

Clarification. I should probably mention that normal shields (not just Air Shields) do confer some benefit against missiles (perhaps based on the shield's defense stat, perhaps based on shield size (round/tower?)).

It's based on the shield's defense stat. It works like: 2d6oe > (2d6oe + shielddefense) if I remember correctly.
