Ark Rune

Wondrous item, legendary

While within 5 feet of this magic rune, you can spend 8 hours transferring a magical property from one magic item to another. Both items must be of the same type, and the item that receives the magical property must be of a lower rarity or value than the item it is transferred from. At the end of that time, make a DC 25 Intelligence check using tinker’s tools. On a success, the item you re transferring the property from loses that property and the item you re transferring the property to gains that property. This may increase the item’s rarity and value, at the GM’s discretion.
