Embed enchantment

This spell causes any Enchant Armor or
Enchant Weapon spell that is still active at the
end of a game, to become permanent,
and the weapon or armor in question
to become a magic item.
Alternatively, a spellcaster may
cast either of those spells after a game
(even though neither are usually an Out of
Game spell), followed by Embed Enchantment.
If both are successful, the item becomes
permanently enchanted.
