Q058: The druid get an spell at Lvl-4, Ice Storm, which is a cilinder, with a range... well, 400+40*Druid Level, 20 Ft radius and 40 Ft. Height.

Altough it deals its 5d6 damage once, it looks to me an exageration, for a divine spell, so much damage and an outrageous long cilinder, then I think:
It's a cilinder, and the 20ft radius base must in the floor, or it's a proyection, and the base can be vertical, and proyect the cilinder, like the Parasite Eve game?
