Bow of... Botulf? Requires no MR save.

Vengeance of the Dead has an MR save, but you can cast it remotely to take advantage of your highest-astral unit with the most penaids. This will kill anything that cannot regenerate or reinvigorate fast enough to survive unlimited attackers, as they increase (by up to 2X) with each casting. I had a very, very high HP unit (...over 500) die to this by killing itself with its own Sword of Many Colors, along with several hundred opponents.

Horror Mark + Send Horror can often kill supercombattants that rely on high protection, fear, trample, ethereality, or some other effects.
