Damage: (level)d200 This spell causes incredible damage. Yes, it does. But it has a major drawback, because it was invented by half-mad wizard: damage type of this spell is just the one victim is least vulnerable to. Yes, it really means that if your victim is invulnerable to one type of damage, fools blast is completely useless. But if victim has no resist much higher that others, this spell is best choice. It is even better than ultrablast in such cases.
