Decided early on that the illusionism blade spells which are replacing existing spells in other casting skills won't add to wield. As some of the spells are concepted, it's just not feasible to give them a wield requirement - veil of mirrored steel, for instance, requires the weapon be wielded at the time of the casting as well as ending if it becomes unwielded.

I don't know if sword-mages get detect magic, but it seems reasonable that they should have it.
