Duplicate

Syntax: cast duplicate <item>

This spell duplicates any item carried by you. It will not duplicate any
magical enchantments, and will make the duplicate nodrop, so only the caster
self can use the item. There's however a chance you fail the duplication
which will destroy the original. Chance of success depends on the percentage
of duplicate practiced.

Due to magical powers not known by the sorcerer, duplicate will not work on
every item.
