A massive battlefield public-address rig with reverb and delay that Donut uses to insult a god and play music.
Donut's voice echoes over the entire battlefield through this rig, opening with a shriek of feedback and a throat-clear before she adds reverb and a little bit of delay to her own voice. She uses it to bellow at Harpocrates, telling him his stolen part is gone, that too many people have touched it, and that he should just accept his body how it is, before cueing up Lil Wayne's "Lollipop."
The bass shakes the very ground and reaches Carl as a distant rumble; the god stops and covers his ears. Donut then opens Donut's Battle Playlist and invites people to message her their songs. Once Carl is inside The Madness Castle the broadcast becomes mostly muted, though he still catches a guy talk-singing about a detachable penis and Donut chewing out Choi Mi-Seon 2 over the PA for the choice.
Heard, not seen: a battlefield-scale public address system with feedback shriek, reverb and delay controls.
Donut's psychological warfare and morale instrument for the land war.
