This spell calls into being a spinning vortex of flames that resembles a burning dust devil; the vortex is 8 feet high and 2 feet wide at its widest. The caster may direct the movement of the vortex in any direction desired, but it may not be moved across a body of water. The vortex moves at a rate of 10 feet per round, and the caster must maintain full concentration in order to direct its movements; if the caster loses concentration, the vortex will move in a straight line at full movement rate until the caster can again gain concentration. The wizard may not move the vortex further away than 10 yards per level of the caster, or the spell terminates.
The caster may use the vortex to attack a single victim per round; he may attack the same target in following rounds, or may elect to move the vortex to attack a different one. Anyone struck by the vortex suffers 1d4 points of damage per level of the caster (up to a maximum of 10d4). A successful saving throw versus spell reduces this damage by half. The flames from this spell will ignite flammable materials on contact, but will not harm most other materials, unless exposure is prolonged. That is, if a creature is attacked by the vortex for only a single round, non-flammable possessions are not affected; if attacked on two consecutive rounds, all possessions must save versus magical fire normally (but only if the target fails his saving throw). Each additional round of exposure inflicts a -1 on all possessions' saving throws (no penalty in added to the target's saving throw).
The material component for this spell is a piece of flammable material suspended from a string; the caster lights the material on fire and twirls it in a circle while casting the spell. He must continue doing this throughout the duration of the spell, and the material must remain lit; if it does not, the spell ends prematurely.
