The Darkness Element is a mixture of Elemental Effects which can be utilized offensively by both hunters and the monster, Meraginasu. It uses the intense cold of wind and ice alongside a strange and unknown power to cause additional damage. However neither element is at full power, only housing 80% of both elements' full power. The Darkness Element is currently exclusive to the Frontier Series and was introduced at Monster Hunter Frontier G3. Meraginasu are the only monsters capable of using the Darkness Element.
The Darkness Element can be infused into weapons to cause additional elemental damage. When a darkness weapon strikes, it will apply both elemental values at once, but will either release a cloud of ice and snow or a burst of black and red energy into the wound, the effect shown will be the one which is most effective on that part of the monster. Darkness Element can be extremely effective against certain monsters.
