This mod changes the level to level 1000 so when starting NG+, the quest level and monster would be similar to your level after when you restart it at level 100. This file fixes the problem.
Install:
Go to: C:\Program Files (x86)\Steam\steamapps\common\The Witcher 3\content\content0\scripts\game\gameplay\leveling and replace levelManager.
Question: Does armors and weapons scale with level?
Answer: Yes it scale with level same as before. However, special witcher armor might change the level requirements.
New at modding. Can someone please help make the script less laggy.
