I want players to be able upgrade their items only if they have the required materials but also the minimum enchanted value for example: draconic bow to be upgraded to dynasty bow will need specific materials and draconic bow enchant value more than +10 and the enchanted value will remain. At first my thought was that the SA multisell would need a modification to have an extra parameter like: <config showall="false" notax="true" keepenchanted="true" minEnchanted="10"/> but it is not possible to edit this as the core needs to be modified. Do you have any other suggestion for that purpose?
