Deathtongue Chorister

The Deathtongue Chorister is a Hive enemy of Xivu Arath's Horde, a Major-ranked Acolyte that is more durable and faster than a normal one. It appears in the Hierarchy mission and in Heist Battlegrounds during Season of the Seraph, and carries a Void Shredder and Solar grenades.

Battlesong

When it reaches an Annihilator Totem it begins charging its Battlesong. If this completes, it suppresses all player abilities (grenades, melees, class abilities and Supers) while giving nearby enemies overshields and aggression. Killing it before the Battlesong finishes prevents this and counts toward a related Triumph.
