You've still got to pass an MR check to get the attack to work, and a terrifying SC should have at least 23-34 MR (probably nearer 30 if enough of an investment), so it would still usually need a lot of VotDs cast to kill it - particularly as until you get sufficiently far into the hundreds of chaff, the SC will probably be able to kill them, so you might need multiple successful castings.
