Looking through the Bestiary 3 the Demilich says the first thing it will do is it's Banshee's wail, The DC is 24, But how much damage does it do? It is not listed. If it is based on it's HD then it would do 150 points of damage. It could also affect 15 creatures as the spell Wail of the Banshee affects 1 creature per HD.
AM I correct to say this is how much damage it does and to how many creatures?
I see the range of it as 20 feet, where as the spell is 25 feet +5 ft per 2 levels.
