Disintegrate

Disintegrate, originally called Aksa's disintegrate, was an alteration or transmutation spell that created a thin green ray that made a creature or a object of a certain size vanish, or be reduced to ash or dust.

Effect
Older versions of Disintegrate made the target disappear no mater if it was a creature, or magical mater or 1" cubic volume of other material. The newer versions spell struck and injured a target, and if killed, the ray caused the creature to disintegrate into a pile of fine dust, although any equipment is not affected. The ray can also disintegrates as much as one 10-foot cube of nonliving matter, even objects constructed entirely of force, but cannot effect magical effects such as a globe of invulnerability. Only one creature or object can be affected per casting.

Material components
In order to cast the spell, the caster must use a lodestone and a pinch of dust. The spell has a range of over 100' (30 m).
