Magic in Dungeons & Dragons

I'm not one of those who thinks that D&D wizards are overpowered and so they are reined in for the Gangs of New Larn setting. More the restriction is to emphasize the rarity of magic - its altogether possible that during the course of adventuring in New Larn a PC wizard might get quite powerful. He just better not get caught using his powerful magic. The purpose of the restrictions is to get the magic in context - my specific house rules will be posted on my web page when I get round to setting it up.
