What is the duration of the Burning effect? Overall, it seems very niche and only suitable against very tough non-humans. Because in other situations, it will deal approximately the same amount of damage in ten turns as a regular spell of equal cost deals on cast. Or does it have some hidden features, such as armor penetration, that other spells of the school do not have?
