Banshee

Banshee appears in the Cave of the Dead area if Vongoethe turns hostile. It is a unique creature not appearing elsewhere in the game series, except by some Mods. There are two of these creatures spawned as allies of the lich. The Banshee's main attack is a variant similar to the spell Wail of the Banshee, except it can be performed at will (not more than once per round). They have most of the typical immunities of a Wraith. It is advised that if fighting Vongoethe, you may want to prioritize slaying the Banshee quickly, unless you are protected against Slay instant death effect or have a superb saving throw versus Death. If Vongoeth is able to dispel any buffs on your party, such as with a Remove Magic, then you may be vulnerable to the Banshee's wail.

Installation of the Sword Coast Stratagems Mod gives this creature a new script, regulating it's targeting and AI, as well detection of some defensive magics.
