Berserker, Kell's Scourge
From Destinypedia, the Destiny wiki
Berserkers will appear invisible from far away but will appear once close enough. Berserkers are armed with a Sting of Misfortune pulse rifle that fires an accurate volley of Arc bolts, which are capable of dealing high burst damage to their targets. They are normally immune to damage due to shield generators on their armor. When approached, Berserkers will release a pulse that suppresses all Light-based abilities as well as fire a powerful charged shot from their Sting of Misfortune as it alternates into the Shieldbreaker; the suppression effect will remain until the shield generators are shot down with concentrated fire. Berserkers will attempt to teleport away when their shield breaks and will find cover until they recharge. Due to their high health, it is recommended to kill them with close-range weaponry capable of high burst damage.
They also drop Radiant Batteries, which are required to insert into specific engines to complete the encounter and progress the raid.
