Dragonhide and Dragonplate

Dragonhide is a rare type of leather armor made from the supple underbelly hide of a dragon. While wearing dragonhide armor you have resistance to the damage type associated with the dragon from which it is made (for example, blue dragonhide armor confers resistance to lightning damage).

Dragonplate is a rare type of heavy armor made from the tough scales of a dragon. While wearing dragonplate armor you have resistance to the damage type associated with the dragon from which it is made (same as with Dragonhide).
