misc questions

[Nethog]

I am playing my first game of D2 and have the following (newbie) questions:

(1) My pretender god was listed in the Hall of Fame but never received a heroic ability. Why?

(2) In the recruit units screen there is a "Holy" status value listed. What does this mean? By the way, my 8-year old son was playing D2 and the holy value was wildy fluctuating to values like neagtive 32, negative 8, etc

(3) In the army setup screen, once you have selected a bunch of units is there any way to deselect them all whitout having to click on each one?

(4) Diplomacy: I understand that the game does not have a diplomacy model (I actually read an older thread on this forum on the topic), however I am wondering what triggers the AI to attack me or declare war via a message. Are my agressive actions against an AI nation "remembered" or does the AI compute this on a turn-by-turn basis? Are there certain nations that are fundamentally opposed and will naturally be more agressive with one another? Those of you who have played any Civ-based games will know where I am coming from.
