Not to be confused with Drakeskin armor, this is earned when you give dragonscales, dropped by High Dragons, to Wade in Wade's Emporium, Denerim. This is the Medium Armor option. All options have the same bonuses.
Note that if you paid 20 gold earlier for Wade's Superior Drakeskin Armor, then you will get the Superior set of this armor, which has twice the amount of fire resistance (70% total instead of 35%). Otherwise if you didn't pay 20 gold then you only get the regular Wade's Dragonskin Armor.
