Necros's dark magic allows him to manipulate the wayward souls of the damned, conjuring their likeness to serve his demands as he desecrates the corpses of the fallen. As you may have guessed, Nekros is a necromancer. While his ability to resurrect fallen enemies is certainly notable, its far from his only useful ability. Nekros' other abilities give him extreme control over enemies. With the ability to push enemies back, terrify enemies into running away, and destroy armour in a large area, Nekros is the maestro of the battlefield. On top of this, he has access to one of Warframe's only loot increasing abilities. With his desecrate ability, Nekros doubles loot for himself and all your squadmates in a large area. Nekros is a solid warframe who relies heavily on his weapons, but factoring in his loot ability, Necros is absolutely worth playing. Id highly recommend Nekros to any aspiring necromancers.
