This question was inspired by Defending Medieval Villages From Gluttons and Savages (please look at that question, it'll be a great reference) and covers Nosajimiki's great point:
"Your monsters are unkillable with medieval technology
The impact toughness of tooth enamel averages about 4 MPa. Modern medium carbon steels generally have an impact resistance of 200-1000MPa, but the stuff knights wore would have been of a lower quality than modern alloys (probably closer to 100-200MPa) and it was about 1.5-3mm thick.
This means that your gluttons have 56 MPa armor, but at ~50mm thick you are looking at something roughly 7 times as difficult to penetrate as a Knights armor, and as is, knight's armor was impenetrable by medieval technology. Nothing short of a renaissance period cannon (not musket) would stand a chance of taking down a glutton.
Savages are even worse at 112 MPa. Their shells are as tough as a lot of medieval steel, but it is about 75mm thick! Savages would be almost as hard to take down as a Civil War era Iron Clad. This means even if you give your peasants the best cannons available at what would be considered the very end of the medieval period, they would still be unable to kill a Savage."
Thus, a good way of killing these monsters must be found. I have a few ideas, but nothing concrete:
Chomper shells can be dissolved by acid (see this link for more on that) and of course, since it's organic, lye should be able to eat through it. However, before the modern age, lye took quite some time to make. Also, it would take strong acid, like "eat-through-steel" acid, to do that sort of damage to a Savage or Glutton.
Fire can disintegrate human teeth, so it can harm either one of these monsters. Their layers of protective blubber would likely make fire more effective by trapping heat inside them, so that's another good point for fire.
Ice tends to make things brittle, and ice cubes, due to their cold and brittle nature, can actually crack and therefore weaken tooth enamel. In fact, ice actually dulls objects that strike it, which is why you shouldn't put ice in your garbage disposal. That being said, the blubber of a Savage and Glutton should protect them from ice.
Self-explanatory; Savages and Gluttons may be intelligent, but that won't save them if they fall off something high enough. That being said, I have no idea how to determine the fall height necessary to actually kill either one.
5. Thin Blades
Whether covered in armor or chitin, both Chomper evolutions are vulnerable to a sharp enough blade in the right spot. Such a blade would have to be thin enough to fit through the chinks in their armor/shell, long enough to penetrate the protective blubber layer and reach a vital organ, and made of material durable enough to last against either caustic or acidic bodily fluid. A javelin perhaps? I'm not sure such a blade would be feasible.
Using hook-like blades to pry armor up and off sounds good, but doing that on a struggling, intelligent, mobile monster doesn't seem feasible. Prying up armor plates enough to enable one to thrust a spear into a Glutton or Savage, however, seems like a good strategy.
Gluttons and Savages both need to breathe, so they can be suffocated and drowned. Their enamel armor will probably make them quite heavy and therefore make it hard (if not impossible) for them to swim. Gluttons, due to their extensive blubber and large stomachs, can probably float if they want to, just like armadillos, but that would require them to gulp down and hold large amounts of air inside them.
Chompers, due to magic and hunger-driven natural selection, can eat practically anything (even garbage) and sense it (smell, see, magically detect, etc.) if something is inedible and/or poisonous them . Their evolutions are the same way. The only real way to poison them is a compound poison, multiple substances that react and make a poison once ingested and blended together by the natural mixing that comes with digestion.
So, You Have Solutions, Why Do You Have A Question?
My question is What Is the Most Efficient Way To Kill An Evolved Chomper?
- By most efficient, I mean a method that is feasible for medieval Europeans, requires the least amount of resources, and will require the least amount of labor to execute effectively. This answer should preferably not involve magic or magical creatures.
