Compatibility

This was made for the Riptide Definitive Edition. Like TheFlayer I do not know if it will work for the original.

Any replacement to Data0.pak will overwrite this mod and any changes inside Data0.pak besides the data/skills folder may break the game. Only files in data/skills have been changed.

Permissions

Anyone may download it and change it however they want. I don't need credit. Anyone could've done what I did if they took the time.

Other Details
Dead Island Definitive Edition has a 1.01 (rounded) increase of experience needed for the next level. Dead Island Riptide Definitive Edition has a 1.11 (rounded) increase of experience needed for the next level. This means that level 100 in the first and level 100 in Riptide does not require the same amount of experience is. Dead Island DE needs 1,268,612 to get from 99 to 100 while Dead island Riptide DE needs 55,400,618 to get from 99 to 100. Because of this, I will add another version where the leveling system is more like the original.

Once again huge thanks to TheFlayer. I know they didn't care about credit, but this wouldn't have been as easy if they didn't lay out the foundation.
