The steps here described only work with the PC version of Skyrim!
- Backup all your save files! I give you no guarantee that anything works or that your game will work after you executed the scripts. Please backup your save files! Normally they are located in C:\Users\<YOUR USERNAME>\My Documents\My Games\Skyrim\Saves\
- Create your perk build with the tool and click 'Download "reset" Script' on the bottom right corner of the page and save the file in your Skyrim application directory as "reset.txt". Then click 'Download "addperks" Script' and save it in your Skyrim application directory as "addperks.txt". On a Steam installation the Skyrim application directory is located in <STEAM DIRECTORY>\steamapps\common\skyrim\
- Start Skyrim and load your desired save file to enter the world of Skyrim. Then open the Skyrim console with the ~ (tilde) key. Enter the following command: bat "reset.txt" and hit return. Then this command: bat "addperks.txt" and hit return. You can hide the console again with the ~ (tilde) key.
Warning: After executing the scripts certain things could break. It is not guaranteed that Steam achievements still work or that anything game related won't break after changing the level and skills with this method. So please make backups and use it only if you are sure what you are doing!
Note: We work with two scripts here: reset.txt resets all active perks and is always the same file. addperks.txt then sets the character level and skill levels to the needed values, and activates all desired perks. Why do we do this with two separate files? Well, I tried it with a single script file first, but it didn't work. If one removeperk command is followed by an addperk command for the same perk in the same file, it doesn't seem to add the perk. So that's the reason why we do it with two files and run the bat command in two separate steps. If you create a new character you could skip the reset.txt script.
