A few questions
 

When looting the battlefield after the fight, is there a chance that ordinary
items will fill the looters slots before the artifacts can be picked up?

If I teleport on top of an enemy castle, and win the battle, what happens to
enemy troops that were ordered to walk out of the castle and invade a nearby
province?

What is minimum range a spell needs to garantee that a caster front and center
will reach a target hidding in a back corner?

Is there ANY way an level eight astral mage loses a mind duel to a level two?
These are effective levels, after banners and buffs.

I think you need 7 levels higher astral magic to be absolutely sure .
If this is a very old game still played with an old patch there was a bug where the roll was open ended so even a s1 mage could defeat there a s10 mage .

Yep.

They are caught in the castle IIRC.

I have no idea. Turn on the grid and make a count. Diagonals might make the distance longer.
