When a wizard casts Wail of the Banshee, he literally screams like a banshee.
|“|| Wail of the Banshee|
At the culmination of this dreadful spell, the wizard screams like a banshee (groaning spirit). Everyone in the area of effect hears the awful cry. Those who fail a Saving Throw vs. Death die instantly. The caster and companions are immune to the effects of the spell.
