Aura of Pain (Demon Hunter)

Shadowy smoke flows out from you and congeals into soft tendrils in a 30-foot radius around you obscuring the caster and any party members within the radius. All attacks relying on line of sight against the caster will be at disadvantage and the caster will gain advantage on wisdom saving throws until the spell ends. In addition, when a fiend or an undead hits an affected creature with a melee attack, the smoke lashes with dark energy. The attacker must succeed on a Constitution saving throw or be stunned until the spell ends.
