Unique Tools and Weapons

I think it would be cool if there were unique items only obtained through exploration and discovery. With rarer and more powerful items being discovered in more dangerous and rare locations. Some examples: Desert Temple: Sand Runner Boots, Iron Equivalent, Faster Movement Speed on Sand. Jungle Temple: Treasure Hunters Machete, Iron Axe Equivalent, Fortune 2 when harvesting Vines, Bamboo, Melons, and Cocoa Beans. Stronghold: Ender Goggles, allows user to look at Endermen, and doubles Ender Pearl drop rate. There's obviously a lot more that could be done with this, and the items I listed are only loose concepts, but the general idea would be that each unique structure would have a chance to drop a specific Tool, Weapon, or Item thematic to that location.
