Gaining Levels

[lch]

Units gain experience automatically each turn, with enough experience they gain "stars" which increases some of their stats, including research for mages. They'll gain exp quicker per turn if they have been in a fight.

Twice born occasionally gives +1 death.

But generally, the answer is that experience will not increase magic skill. I spent ages and ages in my first game making sure a particular mage got as much experience as possible, waiting for him to 'level up' to fire-3 or whatever. But it doesn't work like that, a mage's magic paths are essentially fixed, and mostly experience doesn't help them hugely (although it increases their precision, and they may get a heroic ability of some kind which could be useful).

Leveling up does not give them new abilities. It only makes them better at the ones that they do have. If they can fight then they can fight better. If they sneak, then they sneak better (I think?). If they can lead, then they can lead more. If they can do magic, then they get better results from the spells they can do but not get more spells.

My Exp level 3 prophet is still only Stealthy(+0).

And the 'better results from spells' is only from increased precision as llamabeast says.

For any value that is not initially zero, I think you get:

Morale: +1/exp level
Attack Skill: +1/exp level
Defense: +1/exp level
Precision: +1/exp level
Research: +1/exp level
Leadership: increases per exp level.

Edit: Forgot to add Research to the list.

I don't think anything improves stealth over time -- I've actually wondered why there are no items that give or improve stealth...

I'm pretty sure that experience inproves research skill, too.

[Jazzepi]

There's an item that gives stealth. It's like black heart or something. A blood item.

I know why no item gives it. Because in combination with the Black Heart to give assassin abilities you could create something very scary.
