Wail of the banshee vs regeneration

[Shogal]

Does a creature with regeneration can be killed with Wail of the Banshee? althoug its a death effect, it causes damage, so how does it works? if it can be killed, how do you account the damage? the creature dies when it gets to 0 hit points or 0-con?

It is debatable and a GM call. My opinion, since it is attack the life for of the target then, when there is none left, it dies. Regardless of regeneration. Death effects directly attack the life force. No life force no regeneration.
