Anabstercorian said:3d6 con damage, plus ~65 damage... Yeah, that's a bit much even for a 9th level spell. Maybe a 1d12 con damage instead of 1d6...
The printed one is 1d6 con/10 levels, save for half. Which ends up being weak.
I'm thinking that cold resistance needs to be effective. Maybe 1 con for every 10 points of cold damage actually inflicted.
Even then I'd probably make it Sor/Wiz 8, Drd 9.
