Explain how the Banshee's "Wail of Despair" ability works in practice. I don't quite trust it... Is it worth taking them?
I don't think it's worth taking Banshees, as their wail drains a certain amount of health, depending on the number of Banshees, within three squares.
But it's very weak! And Death Knights always drain at least one creature! In my opinion, they are better!
