Im looking for a way to make custom caracters, edit stats etc. Its not that I want to cheat, I want to roll up the group that I did this adventure with back in the day (on paper). I knew I kept these character sheets for a reason!

Anyone have any tips or advice?

I don't know of any editor, but there is a sort of bug you can exploit:
When you are supposed to roll you attributes, select "advanced". Here you can buy attributes instead of rolling them. Set an attribute to the number you would like and now drag it with the mouse and let it drop where the empty field was (when you could roll your attributes). Switch back to rolling, and your attribute is set. Now go back to advanced and all your points are back, so now you can adjust the next attribute.
This way you could even make characters with 18 everywhere.

If you don't undestand, here is a let's play which exploits the bug as well:

Beside the tip HiPhish described above, you can find (several versions of) a character editor for ToEE here. Somewhere down the same page there's a guide to Hex-editing ToEE as well. Good luck!
