Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods [Mod] 200% Resistance Cap

To merge functionality with a single pak, you need to create the Public folders within the Divinity - Original Sin install directory yourself. So if the pak file was HelloWorld-12345.pak, then you would need to create this folder structure: Public/HelloWorld-12345/Stats/Generated/Data/

Then you could drop in the UncappedResistances.txt into that newly created folder and it should work properly if the pak mod is checked in-game.
