Furies

[Proginoskes]

Sorry for the thread necro, but since Bob never chimed in, I feel like I can add my own idea (related to, but different from, DHBirr's). It has a condition: an enemy Doug can attack must have killed one (or more) of Doug's allies. Doug only needs the tiniest speck of mana to use this song, even for its full length. At the beginning of the song, all of Doug's injuries are healed and his reserves of stamina become effectively bottomless. Over the course of the song, Doug and his Improbability Field both become more and more powerful and vicious. His field might start inflicting transformations (potentially horrifying transformations) on people who get too close, for example. Doug will become stronger, faster, and less careful. During the last verse, Doug can make a person save or die (or possibly just die) just by touching them. The moment the song ends, Doug dies. (Or needs to save or die, or otherwise becomes Only Mostly Dead. Whatever Bob deems best.) The trick is that the initial heal and stamina boost, and most of the mana to maintain the song, comes from the Three-as-Furies. They're not actually getting summoned, so they won't be quite so ticked as with ECSN's idea, but Doug still had better have a Damn Good Reason.
