To spice things up, I propose to add a new skill; Tailoring. Tailoring allows the construction of the tailors table. The table has two slots, A and B, in each slot you can place an item that equips to the same slot(s) when worn, and then merge them to produce and item that has the stats and benefits of item A, and the appearance when worn of item B.
While in inventory, the item will still look like A, so the player can easily tell what it really is, but it will have a small icon in a corner showing what item it will look like when worn.
This would obviously add more cosmetic variety to the game, and it would also mean that it will be harder to guess how experienced and powerful a character is just by looking at his equipment.
Furthermore, it will encourage Jorb to draw more purely cosmetic items, since there's now a higher chance people will actually wear them.

Not that both item A and B is consumed in the tailoring process, so you can't use this skill to churn out a load of fake dragon helmets to equip an army with intimidating headwear.
