Legendary Mapmaker's Glasses
Legendary Mapmaker's Glasses can be found in Supply chests, all facets, all professions. The glasses have +1 to +5 Cartography skill and will go over the skill cap. (Functionality similar to Mining Gloves.) This is useful for getting a small bonus toward a higher quality chest when digging treasure, or to get that next digging radius increase.
Note: %Cartography talismans do not affect Cartography skill, only the %chance to successfully craft maps. Crafting talismans have no effect when digging treasure.
The glasses can have Powder of Fortification applied to increase their durability. Since the glasses are Exceptional they can also be Imbued. One of the most common properties Imbued is Luck, to get that extra little bonus towards better loot.
