When a wizard casts Disintegrate, he literally turns his enemy to dust.
Note: As the description states, there is a good chance this spell will destroy some or all of the items the target is carrying, similar to all frozen and petrifaction effects, use them with caution.
When this spell is cast at another creature, a thin green ray arcs from the caster's hand toward the target creature. Upon contact with the ray, the creature must make a Saving Throw vs. Spell or be transformed into dust. This transformation is instantaneous and irreversible. There is also a good chance that this will destroy some if not all of the items that the creature is carrying.
