Spell use in the Witcher.
 

Has any one found a use for the other spells besides Aard and Igni? I use them all the time and can't see a benifit from the other ones ( granted I'm only in the 3rd chapter). I could possibly see the use of the shielding one to regenerate at times but the other 2 not really.
Anyone out there have success with the other 2?
