Sunfire (At'ar's Fire)

This spell creates a deadly and explosive ball of flame, said to be harnessed from the sun. Creatures killed by the sunfire are typically burned to ash. Damage equals those of a fireball: it causes 1d6 points of damage per level of the caster, up to a maximum of 10d6. Creatures within the radius of the sphere suffer only half damage if they make a successful saving throw vs. spell. Further, sunfire consumes or melts flammable items in its area of effect (items are still allowed a saving throw vs. magical fire).

Yet, there is one key difference between this spell and a fireball. The wizard who casts sunfire is immune to the spell effects. So are all non-living items that he carries or wears. The caster can even center the spell on himself and still escape harm.

The material component of this spell is a ball of sticky gum.
