AC +5 HD 1+4 Move 100% Normal Human Morale 8
Beetle-skeleton tribal humanoid monsters. Plucked from the remote past to serve as minions.
One weapon attack per round for d8 (or by weapon).
Champions have +6 AC, 2 HD and 9 Morale. One champion can act as leader for 2-12 lesser Diluvials.
Leaders have +6 AC, 3+1 HD (min. 16 hp), 9 Morale and +1 to damage. They are accompanied by 2-12 champions as bodyguards.
The special weapon of the Diluvials is a bone-conch triple-horn that acts as a horn of blasting that can also transmute rock to mud once per day. These are non-magical durational effects (10 minutes) and 50% of lost hit points/structural damage is recovered if the target is not destroyed/slain in this time.
Maximum of one horn per 10 Diluvials. Must be wielded by a champion or leader.
Diluvials not commanded by a champion or leader will:
- stop fighting and feast on fresh kills on a 1-2 on d6 each round
- switch allegiance to the most obviously physically powerful character/monster if they fail a Morale Check
Diluvials of all types will not seek cover from magic or missile attack, nor do they make Morale Checks when subjected to same. This is because they are stupid.
The triple-horn does damage tagged as sonic/sound/vibration, and its powers can be adapted to transmute rock to lava and stone to (lifeless) flesh.
Transmuted flesh is permanent and used to feed the mass of Diluvials.
They also like to use the triple-horns to liquify living victims so that they can drink them (traditionally irrevocable short of a wish) - this delicacy is usually reserved for leaders.
While they remain minions/sword fodder, use the leader statblock for all Diluvials to make them a higher tier threat.
Number appearing is 2-12.
If there are at least 10, they have a triple-horn. Or, each has a 10% chance of carrying one.
Number appearing is 1-3. Use the leader statblock. Claw/claw or claw/claw/bite if they are unarmed.
There is only one triple-horn. It has all of the possible abilities. The Diluvials do not necessarily possess it at start of play.
These are the ones I'll convert for Call of Cthulhu.
First appear in Time Killer (1985), and that's where most of the basic information is drawn from.
