[Suzerain of Sheol]

Well, a Rephaim's biggest advantage is how horrifically fast it is, despite its size. They can seriously bullet-time, he probably just overwhelmed the Saint, even if they were roughly equal in all other areas. Those things... strength in numbers -- and I do mean STRENGTH -- tends to help.

And yeah, that item was actually sort of made for me. >_> Sariel is one of more prominent Angels of Death after Abaddon and Azrael, Fen liked the name so she used it for the item.

But they're a class of angel here, probably the most dangerous "generic" enemy we can encounter.
