Are you sure that you're getting the duplicate spell then? Because it should be working if you start the game as a Wizard. Try setting the Element to Water and see if it shows up in the Hydrophist school.
I know I have made a duplicate skill or two back when I was messing around with skills, such as a modified Lava Core for my "Painting the World Red" thread, and maybe for my Purchasable Skillbooks mod. If you want the skill to truly replace the other, you will need to have the normal Skillbook point to your new skill as well.
ok i'll try that, have you managed to change the desriptions of a duplicated spell in this manner?
