Rolling Back Flight

[nedz]

I mean, I'm not doing anything at all yet, this is more of a thinking out loud exercise at this point. To actually answer your question though: probably not. Spider climb, for instance, makes you good at climbing, but it is very situational, and (at the levels it'd be useful) represents a bigger opportunity cost than investing some ranks. Most skill boosting spells seem like that.

It's just that a lot of spells trivialise skills.
