The dev did post some conditions for the mod:
'The main goal was to increase Geralt's responsiveness and mobility,' said Kwiatkowski. The modification brings heightened responsiveness and new animations to Geralt's combat arsenal, as well as addressing some general bugs. Using the Redkit beta, the studio has released the Full Combat Rebalance 2 mod, which was created by Andrzej Kwiatkowski, Gameplay Designer at CD Projekt RED (known among the modding community as Flash). The Witcher developers CD Projekt RED are constantly trying to improve the experience with their games, and the devs have released a new mod that reworks the combat in The Witcher 2: Assassins of Kings. The real problem here is not the ornithosaur oil, it's that basilisks (and wyverns) are now highly (and I mean HIGHLY) poisonous despite consuming the oriole.
I have an enormous issue with this mod: I have tried the mod and didn't like it one bit, the changes were really unpleasant for my gameplay but anyway It's just My opinion the problem is that after I uncheck the mod from alla the chapters the game gets faulty and I can't level up anymore.
