How far in the game are you actually (Act 2?)? To restart the game is a drastic solution. How long have you already played the game?
I'm near the end, it's the last boss in Act 4. And the spell I need is only located in Act 2 (balancing Larian ???). And I really don't want to start over only because of the lack of balancing at the end of the game. Maybe I'm too dumb to find the trick for the end boss, but I think the 2 hours I offered are more than enough for just
