That isn't Common Magic then, if you're using Amplify. There's no reason why Divine Magic shouldn't sometimes be more powerful than Sorcery, since Sorcery is usually the one on top. Also, the divine caster can only do that once per day, whereas the sorceror can do it dozens of times.
Let's agree to disagree on the fact that sorcery is better than divine magic. Yeah it sure is more versatile. But it surely isn't more powerful.
Spirit magicians eat both of them for lunch though.
Heh yeah, it's also pretty cool to bring about eternal night with extension + eclipse.I think it's a real shame that tricksters can't get Extension, cast with Laughter would be really funny. Go on. Laugh. Keep laughing, for ever. Yes, I will dedicate those two points of POW to make you laugh until the end of time. *Edit* Yes I would dedicate those two points of POW to make you laugh until the end of time, but alas, I cannot make you immortal as well.
Just for the record: A pretty cool trick that costs 4 dedicated POW and requires a pact skill of 91+, is Absorption + Amplify (both extended). Cast a common magic spell at yourself for 1 MP, then it restores 10 of your MP. Now you are almost immune to magic, and you have almost unlimited magic points for common magic spells. Sadly you can't buff yourself, but you can still keep your party totally buffed and hit everybody with your magnitude 10 disruptions. And keep a magnitude 10 bladesharp weapon handy at all times. Why people keep insisting sorcery is better I still don't get.
