What is warframe shattering impact?

Warframe Shattering Impact is a mod for melee weapons in Warframe that allows the user to reduce the armor of an enemy by 6% per hit, up to a maximum of 36% reduction. This mod is especially useful against heavily armored enemies like Grineer and Corpus troops, as it allows the player to deal increased damage once the armor has been reduced. The mod can be obtained by completing rotation C of the T4 Void Defense or by purchasing it from other players in the in-game trade chat. It is often used in combination with the Corrosive status effect to further reduce armor and deal increased damage.
