Quoting from Volume 3, Chapter 5 - Part 2:

"Ainz had used various skills to augment this spell, so its potency was greater than normal and harder to resist. Still, it was useless against Shalltear and the Einherjar construct."

In other words, the spell Cry of the Banshee is useless against Shalltear unless it is enhanced by Ainz's special skill which happens to be TGOALID.
