Quicksave, find the file quicksave.json in your .toa-data folder and open it with notepad, ctrl+f "skillPoints" and you'll find a section under unlocked skills where you can change the amount of your skill points, magic points and perk points, change them to the values you want (you can also use magic points to upgrade armor and weapons), save changes to the file and load the quicksave and you'll have the points you want.
There's all kinds of fun things you can change in the file, but beware that you do not corrupt it.
