Many people have told me it isnt, but why not?
for 50 starting sp you get 1d6/level force damage with a save (1sp per casting), its basically like a polar ray that nothing resists but has a save. I dont know about everyone else, but the thought of throwing around
60d6 or even 30d6 for next to free seems pretty appealing, and 50sp only equals one spell so....
Side note, i cast polar ray for 240s-280s all the time, yet it should only do 60d6... not sure whawts going on there... the average should be 210, but the loweest ive ever hit for is 234...
