Disintegrate

Disintegrate is a spell that causes a thin, green ray to spring from the caster's finger. Any creature that is struck by the ray is injured, and if killed, the ray causes 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. 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).
