Thanks for the advice :)
Yes i'm not far in the game , i'm a couple of hours in fort joy and just figuring things out. I had a couple of fights (crocodiles , the arena , boss griff) and i see indeed that my wizard is the most useless of my team, not completely but most of the time i'm using shearing daggers and fossil strike with him and teleportation since i got that glove on him. But can i still pick skillbooks from other school that make him more powerfull? Now i have Geo and pyro skills invested on him. On Ifan i'm investing in Summoning.
About the wolf, i don't even have Source points yet to caste him. I heard you get those points later in the game. But should i replace the wolf or just keep him while i'm investing in summoning anyway.
