Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Stats Increasing EXP required for LVL up

I'm not sure if experienced required for a level can be altered. You could alter the "Gain" stat of enemy stats and whatnot to help with that (in fact there may already be a mod that halves enemy experience given). Gain determines the amount of experience given.
