As a ruler of undead creatures, Brahms has seen all the tricks that Harpies might try to throw out. Sure, Empyrea may be a slight upgrade over harpies, but the Vampire Lord surely has her number here. While her decent physical resistance should ensure that Empyrea will survive for a few turns, Brahms’ near physical immunity will mean that Empyrea’s only hope of damaging him is a puny once-per-round Zap. Anything else will be like a pigeon clawing at a wall. And once Brahms’ Bloody Curse finally activates, no amount of physical resistance is saving Empyrea from becoming another notch on Brahms’ belt. Bye bye birdy!
