I don't think it is a bug, but I am wondering about this particular spell. It would seem to me that the difficulty in getting this spell up in skill is much, much, harder than it is for the other level one invoker spells. Is this by design? Or is it something worth taking a look at? Just a thought since I have had bad experience with it ever several invokers recently and cannot seem to get it to go up very quick even with the affinity at 10, and playing a svirf that is supposed to have an a certain natural talent with that element.
