Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Help/Tips/Tricks Tomb under the maze too heavy

I was able to open it the first time with the Red Prince with about 20 str. It does not seem to be working for me the second playthrough. I'm not sure if there's a secondary part to it though. Like high strength and ... something. Warfare? A lever? Idk.
