The tower amplified both Lith's and Solus's abilities, so they had created the Nova series of spells that exploited the tremendous might that tapping into a mana geyser bestowed upon them.
Raging Nova was the evolved version of the tier five spell, Raging Sun.
Raging Sun was a combination of fire and earth magic which generated a powerful explosion along with flames so hot that they could melt stone. Its effects were akin to a volcanic eruption.
Raging Nova, added a third element, air, to both expand the area of effect of the explosion and raise the temperature of the spell. White flames engulfed an area of over one hundred meters (330 feet) around Lith, destroying the focus point of the arrays along with everything else in their path.
The undead were resistant, not immune to the elements, and Raging Nova was more than they could take. Creatures like Vampires or Ghouls died on the spot with their bodies torn apart and burned so fast that they were unable to regenerate.
