Sun Knight said:I find wand +3, or a tome +4 quite arbitrary and contrived. In fact I find it rather stupid and lame in terms of design.
Mechanics are almost by definition arbitrary and contrived how could they not be (how is a +1 wand more contrived than a +1 sword)? It's the implementation that's important.
This implementation has the potential to be pretty good. My understanding is that there won't be saving throws as such but defenses - seems the +x wand, for example, will help the wizard penetrate certain defenses better. seems simple and elegant to me.
