Hey all.

Been playing my first game of SK the past couple days. Great game so far. A few questions popped up that I couldn't seem to find the answer for when I tried Googling. So I figured I'd try asking in here, The questions are about respawning, spells, and experience.

Respawning:

1. Do lairs respawn new units to fight? If so, how often and can that frequency be changed by game actions?

2. Do the lairs themselves respawn on the map somewhere after some time once I clear the original lair?

3. Do quest locations like inns, caves, dungeons, etc. respawn?

Spells:

There's two spells to improve terrain. Restore Land and Enhance Land. I'm playing on a huge map, and I've explored in about 40 tiles in each direction and only found a small spot of fertile land on the big island continent I'm on.  Thats a 80 x 80 tile area with only 2 city sites. My original city and the 2nd city site. So I am wondering, can everyone get Restore Land and Enhance Land to turn grass into fertile land, or change swamps or hills into fertile land? Or is it only for the Guardian sovereign?

My first (current) sovereign is Commander + 8 Enchant spell books. I read that this was the best set-up for a first play-through of the game.

 Experience:

1. Is there a maximum level for units and heroes? Level 50? Level 100? Or no level cap?

2. If there are no monster or lair respawns, what's the best way to level up units and heroes? Early game? Mid game? End game?

Answers to these questions would be greatly appreciated!
