|Douglas Muir 406|
Doug's wizard build is one of the first blasters I've seen that doesn't have the dip for Crossblooded Sorceror. Looks pretty effective, too.
It doesn't require a ratfolk, either. That build works fine with humans or elves, or really anything that gets a bump to Int. It's not quite the ultimate blaster in terms of raw damage, but it's close, and it's very flexible.
The bound object is key, mind, because eventually your GM will start getting tired of watching his monsters get flash-frozen, melted, and blasted to bits, and will start throwing golems and suchlike at you. "Your ready spells are all blasts, right?" "Gosh, yes they are." "Heh heh -- " "Sure glad I have my bound object with me! Grease." At higher levels, scrolls add even more flexibility; this is why going cyphermage and Enhance Scroll is so attractive.
