Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Guide to maximizing EXP gain on a run?

Level 99? The level cap is at level 36, any more XP will put you back at level 1. Well, at least that's how it works in the editor. I guess you can remove the cap via mods, but I can remember a dev saying that the cap was initially at level 50 and that already broke the game. Probably since HP scales exponential (the overflow would give you a negative max HP).

But yes, the actual XP you can get in a run is much smaller. The more interesting question would be what is the minimum level you can finish the game with?
