Firebolt

This spell calls forth a projectile blast of fire, dealing damage to its target. It may optionally be aimed at a target up to a room away from the caster, though it will do less damage based on the distance traveled; if cast across rooms that are affected by blazing inferno, no damage will be lost. Most spells which block vision into that room will also block long-distance firebolts, but firebolts will penetrate walls of ice at the expense of losing more damage.
