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 matter if it was a creature, or magical matter, or a 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 was not affected. The ray could also disintegrate as much as one 10-foot-cube of nonliving matter, even objects constructed entirely of force, but it could not affect magical effects, such as a globe of invulnerability. Only one creature or object could be affected per casting.

The spell has a range of over 100' (30 m).

Material components
In order to cast the spell, the caster had to use a lodestone and a pinch of dust.

History
The wizard Parwyyd Hanifar used a disintegrate spell to destroy his own Great Door in order to end the threat it posed.
