Well, of course, but I think it is powerful nonetheless, and can be a reason for some powerful aegis out there other than through Wizards Communion, which I like, as it adds to the idea that there are several ways to do the same thing through Hermetic Magic.
And I agree with you on Minor MF: Arcane Connection. It really doesn't give a "theme" or specialty to one's magic, which is one of the joys of Focuses.
(btw, cuchulainshound, you were right, I first wanted to create a thread on this, but reasonned that this had to have been brought up and did some research )
Well, it would be most useful to a ReVi specialist, which can ward against every supernatural creature with 4 spells. Not so broad. Then, there are the watching wards (which I didn't intend as "wards" proper) and wards against iron and all, but still, this is no more wide than a Bird focus, say.
I should maybe rephrase it as "ward against creatures with might", but that's all, IMO.
Major Magical Focus: Improving the body. Maybe a little too broad, but this allows the raising of characteristics, one's appearance, night vision... However, I wold disallow it for spells that destroy one's perfect form, such as giving claws or a tail.
A focus on Curses, minor if from a single form, major otherwise.
I wonder if a focus on a color would work. Probably not, although it would be cool to be "the blue magus".
Any other good focus ideas? I think this is maybe the best vertue out there, as it really "themes" one's magic, which becomes the "insert focus name" mage.
