"Man O War Hell on Stage" broadswords you in the face with heavy metal thrashing. No sooner do the 4 kings of metal start rocking does the crowd start chanting. And only a gelatinous cube would disagree. I give it 4d4 magic missles.
Not even the Boots of Escaping can save you from the malicious assault that is Manowar. But take heed...you will lose 10 hit points just by listening. This is not for clerics...only a true multi-class fighter/magician can survive the fury.
If they can get Yngwie Malmsteen or Krokus to open for them....
