History of Battlesong

Battlesong is a phase of Heist Battlegrounds on the Moon. Once a Host falls, a Deathtongue Chorister moves to the Annihilator Totem and sings Xivu Arath's warsong. The song stops abilities and supers and buffs nearby enemies, so the Chorister should be killed first. The "Silence the Alarm" triumph requires stopping it. Guides are from Season of the Seraph.
