Synthesis Spellcraft

Upon casting this spell, you touch two magical items, of the same type. The spell merges the two items into a single item that possesses the properties and abilities of both original items. The physical appearance of the new item is a harmonious blend of the two original items.

For example, if you cast this spell on a Sword of Sharpness and a Flame Tongue (both being weapon type), you might get a Flaming Sword of Sharpness that has the sharpness ability of the Sword of Sharpness and can be set aflame like the Flame Tongue.

This spell leaves a lot of room for imagination and thus supervision from the DM will undoubtedly be necessary to know what would be allowed or not.

The spell can be dispelled by a successful dispel magic spell. If dispelled, the objects return to their original form and separate from each other.
