Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Game Master Challenge rating or how to scale encounters

You can increase or decrease the level of every creature in the encounter at once. Theres a little trick. If you have a level 3 and 5 when you hit level up the 3 becomes 4 but the 5 stays till you get to the same level then they both go up. Or you want to sleep them first level them up to the same level then delevel.
