The Dragon Element is an Elemental Effect which can be utilized offensively by both hunters and monsters. It uses a strange and unknown power to cause additional damage. Monsters that are capable of using the Dragon Element can be found in a wide variety of environments, and are generally extremely powerful and oftentimes quite rare. Most monsters which utilize the Dragon Element can inflict the Dragonblight status, which can temporarily render an opponent's elemental effects useless. Most monsters which wield the Dragon Element are themselves weak to it.
The Dragon Element can be infused into weapons to cause additional elemental damage. When a dragon weapon strikes, it releases a burst of black and red energy into the wound, which can be extremely effective against certain monsters.
In Monster Hunter: World, Dragon Element weapons have the Elderseal property. Repeatedly attacking an Elder Dragon with Elderseal weapons can temporarily disable their passive abilities, such as Kirin's lightning armor, Vaal Hazak's miasma veil, or Nergigante's regeneration.
