Just had a game where
Prince died n1 to an empowered attack when I was TWing him. The next night, I died to an empowered attack even though I used my own delay death on myself.
Im suggesting Chrono TW and self death prevention still works to prevent death against Empowered deaths, you just cant swap a death that is empowered to someone else. So you would die in 2 days (unless you delay it again), but cannot prevent the death totally by swapping it to someone else.
Firekitten suggested that a day ability gets added to allow his night tw to work on empowered.reaps.and strikes.
