AI Improvement: Enemy spell choice

[GeneralDiomedes]

I am posting this in its own thread so it doesn't get buried as an off topic post in another thread.

The suggestion is to improve the enemy AI by increasing the effectiveness of enemy spell choice. There are two components.

1. Give enemy casters some information on innate immunities according to creature type. For example, the enemy should know that Hold Person doesn't work on Warforged, and that Scorching Ray doesn't work on Hellhounds.

2. Give enemy casters the same 'immune' message as players (presumably due to player equipment and/or buffs above and beyond innate immunities) and allow them to switch to another spell if they encounter one. The enemy caster will not try the same spell on the player again.

I believe this would be relatively simple and cheap way to improve the AI.

Thanks to Roguewiz and Talon Moonshadow for ideas around putting some more intelligence into enemy caster spell choice.

What I can see is:

MOB trys to cast a poison on a player
MOB notices it didnt take affect.
MOB switches to a different spell.

In regards to Warforged, the MOB just shouldn't try casting the spells they are immune to. And other than having an overwhelming sense that the player is "Good", IE, Paladin, there wouldn't be a way to say "Hey, he's immune to fear! Lets not cast that spell on him"

I think the only way do this easily is to just varry the spells more.....or have the AI get some feedback.....like when I get an immune message I try something else.....let them try to hold a WF once.....then use a different spell.
(That's what I do everytime I run VON4 )
