Its my first mod ever so lets see how it goes.

Compatible with Patch 1.12. Doesnt work with patch 1.21 (i think the mod is not even needed now)

Thanks to this mod http://www.nexusmods.com/witcher3/mods/593/? i knew what file to look at to uncap the level. What i just did was change a few lines in levelManager.ws so you can get experience and level up past lvl 70 till lvl 100. You dont get dmg/sign intensity/vitality but you do get an extra ability point per level.

Thanks Tyrite for the fix to get the pop-up when lvling up.

To edit the max level:

-Edit content\scripts\game\gameplay\leveling\levelManager.ws
-Search for "GetMaxLevel" and change the number 80 in that line to the max level you want up to lvl 100 (default for the mod is 80).

To get the pop-up:

-Edit content\scripts\game\player\playerWitcher.ws
-Search for "if ( hud && currentLevel < 80 )" and change it to the lvl you want up to lvl 100 (default for the mod is 80).

What it does?:
Increases lvl cap to lvl 80. You can edit this in the file to any level you want up to lvl 100 (going further gives you negative exp hehe), see above how.

Installation:
Either use NMM or just put the mod in the Mods folder.

Uninstallation:
Just delete the mod, you will go back to lvl 70 but retain both the experience points and the ability points you gained with the mod.
