[Butz]

Well, I like the idea of things like house upgrades, and cosmetic changes.

Maybe make the cosmetic changes something like:

Scroll of Flame Shield Illusion: Transforms the look of any marked shield into a flame shield. Stats remain the same, the item can no longer be traded. Shield is renamed similarly to prepped weapons. (i.e. Butz's Shield of the Sun +6 (Flame Shield Illusion) (Stats go here) )

And so on... Of course, make sure that the designs in the shop are unique from anything that can be found in game normally. Maybe even have contests occasionally to have player designs added into the shop. (Bring back some of the player customization that Graal has been lacking in recent years)
