It does a dice roll to see if it succeeds basically. It does not have to actually do it.

The success chance is not known. Likely it is a formula that involves the difficulty of the quest weighted against the combat rating of the AI's army doing the quest.

Quests can specifically have a tag that blocks AI from picking them up.

Each quest has a series of tags that defines what is gained when completing a quest. Amongst these, a particular position in the XML indicates the "general success" reward. I am guessing this is what the AI gets if it wins.

As you can tell, I don't know much about the AI, mostly guessing here.

Me 2 , I really hope they learn to do quests at some point, although I do understand the need for the AI not to do them (Would make custom quests a pain for the AI to figure out).

Why doesn't it actually go through the steps though ? Can't be too difficult, most steps are about going from A to B, fighting something and selecting an option.

I just think it would be easier to actually have the AI try and do each step just like the player would be easier than trying to abstract the whole thing behind a roll (if you want that roll to make sense at least, you could always just put some simple roll check and be done with it but that's just not very good imo).

It's because as quest makers we are jerks.   We say things like

You come upon a small farm where the inhabitants are all deathly ill from a sickness

Options:

a) Leave the family to die from the plague

spend 200 mana to heal the family

c) search for a cure in the deathly swamps

d) Steal all their food and valuables and then kill them mercifully

Can you imagine the coding involved to make the AI even semi-intelligent at doing this quest.  It would be more than it is worth,  and to make the quest would be very hard if you had to write "computer code" each time to explain what the option mean to the AI.     Don't get me wrong, I'd love the AI to be able to do quests, I just don't see a realistic way to have them do it and to still have quests with open ended text and infinite options.

Umber IS in the game.  They have descriptions, and everything all made out. And they were even updated when factions went from 2 faction points to 3, Capitar gaining lucky.  The only thing they are missing is a Sov.  I create a sov for both Umber and Capitar.   Capitar is my main enemy in my current game.

Yeah I thought about that but you could just have the AI randomly select an option. Maybe even make it more faction/sovereign specific, give each choice a flag that shows the type (Evil, Good, Conservative, etc) and then each Sovereign could pick the choices specific to his flavour.

Really, as long as no choice instantly kills you (which shouldn't be the case), just randomly selecting one would be enough.  

AAAAActually, I have a quest that instantly kills you if you select an option.
