I wasn't too keen on the Conjuring skill group either, to be honest. The problem was, I had so many skill group points and nowhere to put them. Half of the groups I don't or can't use, half of the remaining are things I don't want to get the group for, and that leaves like 2 groups. In the end, I figured losing 2 dice from lost specializations was a small price to pay for a load of extra skill points to spend elsewhere.
Again, Skills B is just slightly too low for the concept. Sadly.
250 Reagents would get me 2 Force 5 Spirits (then I'm out), but I figure I can maybe get 1 Force 6 or just a couple of Force 4s to tide me over for a bit.
