Vengance of the Dead

[Agema]

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.

Yeah, in power terms it's quite fair imo. Especially as a simple Mind Hunt will do the trick for many SCs even better.

But I still find it extremely ironic, that some invulnerable never tiring supercreature would just turn around after 5 minutes of fighting and commit suicide.
