Wondercraft

Wondercraft was an extremely powerful spell that copied magic items.

Effects
On casting the spell, a mage automatically created, without the need for an object to enchant or for many material components, a copy of an item they had created or whose properties they had handled within a year and a half, maybe more for more powerful wizards.

Each property had a chance not to manifest, inversely proportional to the mage's ability to manage dangerous magic; even those that did had a chance of over one in four to be twisted into something else, something random, and for objects with more than two properties, the chance quickly escalated into near-certainty.

The caster's health was damaged by the spell. Though it was temporary, unlike that of a permanency, it increased exponentially if more than one such spell was used within 24 hours- no one would survive casting it four times.

The items lasted for at least 18 years; there was no way whatsoever to make them last longer.

Components
Besides verbal and somatic components, the spell required three drops of water, three drops of dew or a flask of captured mist, three stones of any size, and three pinches of ash from a fire. All of those had to have been touched by magic at some point.

History
Azuth made this spell available through Elminster sometime prior to.
