see the final section of this guide for a note on this. There should be NO other text in your file. Save the blank file in your Skyrim\Data folder. Name the file something you will remember, such as 'skillcheat.txt' but DO NOT have any spaces or special characters in the file name - letters and numbers ONLY.
This will allow you to earn perk points AND choose whether to increase your magicka, health, or stamina for each individual levelup that you gain. But it does it in such a way that the game will recognize them as being 'naturally earned' and so you will gain the associated levelup like normal, the next time you open your Skills menu. All it does is max out all of your skill levels. Now if you want a PURE cheating experience that only affects your character's skills and levels, without 'breaking the game' in any way, that is what this is for. It will NOT affect your graphics, sound, or any other technical aspect of the game.
It will work with ANY mods (or no mods) whether official or community made. This cheat will NOT add anything to your inventory.
