133 Levels v1.1  

Disclaimer: I know how people play DnD and levels like this are not the most popular thing, BUT if you think this mod is blasphemy, then you should know that it was not made for you and not for people like you, please pass by and don't come back again.

Description: the mod was made for those who are greedy for power, for those who want to see all the dialogue options for all classes, in general, do everything in one playthrough. Since the maximum level is 12, then for each level (in theory) Larian was allowed to take a class, which does not break the game in a technical sense. But this definitely breaks the balance, as the difficulty progression will have to freeze at level 12. 133 because 11*11 (11 grades with 11 levels) +12 (12th grade with 12 levels). At level 13 (class, not character) the game crashes, technically level 13 is not implemented, so you have to take only one class level 12. If you raised the character to the 12th level of the class, then without raising the level further, go to the mummy and reset the levels, redistributing everything.
The progression is simple:
level digit * 100, i.e. 2 - 200 experience, 10 - 1000 experience, 133 - 13300 experience. Therefore, I'm not sure if it's theoretically possible to collect 1035600 experience points and reach the maximum level.

Important: before installing the mod, reset the level and save, after installation, return to the game and start distributing

If you decide to get rid of the mod, thereby restoring the natural course of things, then just come to the Withered and reset the levels, then save and exit the game, then delete the mod files and return to the game, then distribute the exp and you will have the level that Larian is expected of you at your stage of the game (maybe not 12th).
