Anger Management

I am no musician, though I've spent many an hour enjoying the entertainment in Tazavesh. Giving this horn a voice will require the harvest of strong emotions. Anger seethes unrestrained within the damned unfortunates consigned to the River of Souls. Use this siphoning device to drain the rage of these furious shades into your instrument. The shrieks of fury that you acquire should allow you to pierce the Maw and reach your allies. The tune, I suspect, will not be a popular one.
