Flame Strike

The creation of a Fire Field in itself is a rather useless spell, as it hardly hurts the caster's foe.

What however, if the spell creates fire fields directly under all of the caster's foes in an instant? This spell does exactly that, with devastating results, as only few foes can survive the sudden outburst of flames from beneath them. Even worse (for the foes), there is no escape from this spell, as there is no time to react at all.
