I have recently conceived of a fifth member of the Little Four, the four most common monsters in my fantasy world: Bitbugs. These cute little bugs have rounded bodies (they look sort of like blimps), big eyes and mouths, and pudgy stump-like legs. Think Kirby in insect form.
However, like all monsters, Bitbugs enchant whatever living thing or item kills them (within reason; more on that below). Their death effect (or the enchantment resulting from killing a Bitbug) is Synergy. You see, every Bitbug is just part of a whole, a single piece of something greater: the Bithive. The Bithive comprises a Bitbearer (the Queen) and the Bitbugs she bears (the Queen's children).
Since the Bitbearer is born from a Bitblotch (a fleshy structure born from the ground when chaos magic penetrates it, basically a tumor of reality), and the resulting Bithive is connected by the Bitblotch's energies, killing a Bitbug with something links that something to the Bithive. For example, if a sword is used to kill a Bitbug, it will then "sync" with and become an extension of the Bithive, gaining a life of its own and the ability to move at the cost of being essentially born a slave of the Bitbearer.
A similar effect happens to any living thing that kills a Bitbug; they become a subservient member of the Bithive, investing all of their talent, energy, and even life to defending and supporting the Bithive. There are two different kinds of Synergy for living things, Martial and Regal, one gained by killing a regular Bitbug with one natural weaponry (Ex: fangs and claws), the other gained by killing the Bitbearer herself, with or without a weapon. Regal Synergy can only be gained by females.
Creatures enchanted by Martial Synergy become stronger, faster, and tougher, gaining chitin armor and enhanced natural weaponry. They are then called Soldiers. Creatures enchanted by Regal Synergy become the prime version of themselves (albeit with chitin armor and some other insect features) and gain both the capability to control anyone or anything under Martial Synergy (specifically, Synergy from Bitbugs born of the Bitbearer that you slew to gain Regal Synergy) and the ability to Spawn Bitborn, an unnatural fusion of Bitbug and whatever species the enchanted creature is. These lucky creatures are called Queens.
Summary-TL;DR: Bitbugs are essentially Kirby in insect form, and they are born from a Bitbearer, which in turn is born from a Bitblotch, a sort of tumor born when chaos magic not only warps but infects (read: possesses) part of reality.
If an item is used to kill a Bitbug, it will gain life and the ability to move, becoming a new member of the Bithive (Bitbug collective; there are many separate collectives, each born of a different spot where chaos has infected this world).
If a creature kills a Bitbug with its natural weaponry or eats a Bitbug, it will become a subservient member of that Bitbug's Bithive, gaining chitin and enhanced natural weaponry and becoming stronger, faster and tougher to boot. This peculiar effect is an enchantment called Martial Synergy, and those holding it are called Soldiers.
If a female creature kills or eats a Bitbug Queen, or Bitbearer, it will become the best possible version of itself and gain three things: 1. chitin armor (and other insectoid features, like antennae and wings), 2. membership in and control of that Bitbearer's Hive, and 3. the ability to spawn Bitborn, which are a fusion of Bitbug and whatever species the Bitbearer's slayer is. This enchantment is called Regal Synergy, and those holding it are called Queens.
My question is, How Useful Would This Be To Humans?
-Specifications:
Please assume that said humans live in a typical medieval low-fantasy world. If that isn't clear enough, let me know and I'll be more specific.
Since a Bitbearer is aware of Synergy, it seems that she would order Bitbugs to seek out and get eaten by dangerous animals so she can better defend herself. This would seem to make it very difficult to reach the Bitbearer in order to gain Regal Synergy, the only obviously useful version of Synergy, unless one is a necromancer (has the advantage of sheer numbers) or a dragon (has the advantage of SHEER POWAH!), or unless someone predicts the appearance of a Bitblotch and kills the Bitbearer as she emerges.
The last one would be difficult, but for the sake of the question, let's say that there are crystals one can use to divine the location of a future (or present) Bitblotch, like a divination rod, but that Bitblotches only show up in remote and hazardous locations, like a deep cavern, a barren island, or inside an active volcano. (Bitbugs are born of chaos, so they are of course adapted to or in other words, immune to the hazardous locations of their Bitblotch.
I'm looking for ways humans can somehow turn Synergy to their benefit since it seems like a significant detriment. To make this clearer, each and every Bitbearer causes destruction and chaos in the area around their Blotch, since areas successfully overcome by discord in this way are infected by the Bitblotch, therefore spreading it.
A human with Regal Synergy has control over the Bithive 24/7, a human with Martial Synergy is under control 24/7.
