Using this spell the caster summons 3 different arcs of fire to form from 3 different point in the ground and to converge on any one point in between all of the first three points. These arcs are 2' in diameter each, and do 2 points of damage per level of the caster. At the spot they converge they form a 12' diameter sphere of fire. Any creature caught in this sphere takes 2d4 points of damage. This all happens during the first round.
At the beginning of the next round the sphere blasts out ward in 8 directions, N, NE, E, SE, S, SW, W, and NW. As they blast outward, they do 1d4 points of damage for every 2 levels of the caster. The blasts continue for 2' per level of the caster.
The material componets for this spell are a peice of gold wire shaped in a perfect arc and a small pinch of sulfur. (please feel free to change anything about this spell to suit your campaign worlds.)
