hmm , so looking at some of the weird rules ...
Specific Recharge times + metamagic special rules = probably not a good idea.
Lengthening the recharge time, can put that off, to longer than non-recharge daily picks.
Imbue With Spell has a tag to it, an obvious caveat.
But it does work as a get-out-of-jail extra use of lower level spell,
so long as the someone else uses the spell soon.
Enchants are kinda screwed. I understand their charm-o-rama suspicion.
Still, it's quite a relative nerf. Worth ditching the School if specialist Wiz.
