A free mod for Mount & Blade II: Bannerlord, by Marek15.
Leveling Rebalance is a mod that rebalances the leveling system by changing the way attributes are calculated. It also changes the way items are valued.
When you start a new game, you will have your character at the lowest level. As you play, your character will gain experience and levels will increase.
The plus version of the mod fixes some issues with the way items are valued. It also rebalances the game a bit by giving more experience to items that have more value and less experience to items that have less value.
The standard version of the mod only changes the attributes and leveling system.
