Fallen & Fallen Shaman: localBlood=1, Bleed=1
Brutes: localBlood=2, Bleed=2
Yetis: localBlood=0, Bleed=2
Corrupt Rogues: localBlood=0, Bleed=1
The functions of "localBlood" and "Bleed" are not completely clear at the moment, but "localBlood" does seem to determine whether a monster affected by open wounds will actually display blood splatters on screen, even though they are still taking damage from open wounds. While it has been suggested that "Bleed" may determine a monster's susceptibility to open wounds, many types of undead and some animals have Bleed=0, yet they are not (all?) immune to open wounds either. It could very well be that open wounds is simply an unresistable attack too.
