A free mod for Mount & Blade II: Bannerlord, by Dealman.

Tournament Rebalance is a mod for the game Mount & Blade II: Bannerlord This mod aims to rebalance Tournament and Arena Practice by introducing combat XP rewards, using the same formula as normal combat – but reduced by 50%. 

This is how it works: 

First of all, it increases the renown gained as well as introduces a new mechanic for receiving a bit of gold as well for winning. 

It also changes how you win renown. By default, you would only win 3.0 renown, whether you performed well or not. But with this mod, the renown you receive will be based on some factors, such as your number of kills or who you’ve killed.
