[Saber Cherry]

A force costing 8*(10+20+20)=80 water, 160 death, and 160 slaves should be expected to wipe out virtually any normal opposition. They're vulnerable to fliers, priests, archers, cavalry, and especially single-target spells like mind burn / soul slay / sleep / frozen heart that don't work on SCs due to their high HP and MR. And they can rarely survive Horrors from their horror mark. Consider that force attacking a Queen of Elemental Water leading 30 Claymen, two Spectres leading 60 Wights and 100 Longdead Horsemen, an Arch Devil leading 25 Devils, and 8 Priests.

As Jotunheim, I find Lifelong + Frost Brand + Skull Talisman on a Scout or Soul Contract + Frostbrand + Lucky Coin + bodyguards on a Jarl to work well, as they can kill Lesser Horrors. But even Jotun Scouts are not safe to use alone, and are best as part of a well balanced army, including grapefruit.
