Q: Can I add item title and surname multipliers to my custom?

A: Yes, you may... however you must already have the item with the multipliers and be adding it to a custom that already has the regular items stats. For example, if you have an item called "Shivers Hat" and it is a personalized Ruby crown and suddenly you find yourself in posession of the coveted "Powerful Ruby Crown" you can add the powerful multiplier to your custom. However you must relinquish the Powerful Ruby Crown to us, and donate 10$ OR use a service ticket (the service ticket would be an extra one on top of the regular one used to change the item, due to the powerfulness of the item)

Note: You cannot "stack" items to create one powerful item. If you want "Powerful Ruby Crown of the Jabberwocky" you MUST have that item. You cannot pair "Powerful Ruby Crown" and "Ruby Crown of the Jabberwocky" together.
