I agree that those two spells are kind of overpowered at higer levels.
However I don't agree that "Hellspikes" should be resistable because you will need an unresistable spell at the later stages of the game. Maybe its damage can be lowered a bit. The same goes for "Burning Wall" too.
Just my two cents! <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
