1. The tonal inverter requires two willing, consenting, adults to operate; one harmonic modulator to generate and prepare the sound wave, one resonance intonator to release the prepared sound wave and disrupt Sotha Sil's modified energy-stealing device. 2. Harmonic modulator operates the tonal inverter, nearby but out of direct combat, while resonance intonator engages device-wielder in battle. 3. Harmonic modulator works the tonal inverter controls to build a wave of sonic energy.
