So, this is a rather interesting question, please bear with me. In Alendyias, there is a flying creature called a Flamoth, a moth-like creature with a fuzzy, football-shaped body, two beady eyes with a giant, lidless third eye in the forehead, and four wings that resemble a pair of jaws.
It is not the creature itself but its wings that this question concerns. You see, each set of wings is shaped like a set of flattened T-rex jaws, with one edge (top or bottom) having teeth-like serrations. These edges face each other, so each pair of wings on the opposite sides of its body is essentially a pair of serrated scissors.
After the creature is killed, the Drop Mechanic I created (for more on this, please see the first three paragraphs of Preventing Dead Monsters From Spawning Undead) recreates or repairs its Wings, or Wingjaws.
Now, since combining monster parts and molten metal usually makes some really cool steel items (ie. weapons/armor) this was attempted as soon as people got their hands on some Wingjaws, and they discovered something....odd. Like, really odd.
Wingjaw-steel items, like Wingjaws, float. They do this by manipulating gravity, harnessing the power of magic to decrease the force of gravity; basically a magical version of a blobfish. Blobfish are slightly less dense than water, so they just float where they are.
In this case, Wingjaw items decrease gravity just enough to make themselves float off the ground. In this case, wearing Wingjaw armor is like wearing a life vest; it keeps your head above water (AKA keeps you off the ground) but doesn't do anything else. It buoys up the wearer, but it doesn't keep them off the ground.
This is because steel plate weighs 15-25 kilograms, while the average (global) weight is 62 kilograms. Let's assume 50 kilograms, or 110 pounds, instead. Now, if we assume Wingjaw magic makes steel have a weight relative to helium, because helium floats, then it gets interesting.
A normal balloon can lift 14 grams of weight, and it would take 3,57l.42 of those to lift a 50-kilogram person. Assuming plate armor weighing 25 kilograms, that means half the above weight and therefore half the lifting force. Ergo, you'll stay on the ground in Wingjaw plate, but it sure wouldn't be as heavy.
As for Wingjaw weaponry, remember how the gravity is decreased for Wingjaw items? Yeah, well that's because magic disrupts gravitational force and turns some of it into potential (kinetic) energy. Now, I don't know what the weight of steel is compared to helium, but the difference there is the force added to any strike made with a Wingjaw weapon.
That same nifty trick makes Wingjaw armor viable; that potential energy only takes effect when either pushing back, against a blow, or when striking an opponent. It doesn't amplify a blow to the armor against the wearer, rather it (hopefully) negates the blow by pitting it against the potential energy inside it.
That same gravitational disruption makes it so that momentum for a Wingjaw weapon is as normal, so it still acts as if it has the same mass while being light enough to float. Yeah, sort of confusing, I know.
So, basically, take some Wingjaws and some iron and you can make floating steel with an interesting take on gravity. My questions are: How Much Of An Advantage Does Wingjaw Steel's Levitational and Gravitational Properties Confer?
Specifically, how useful is floating metal when used for weaponry and armor? Keep in mind it turns excess gravitational force into potential energy, which is added to the object's motion.
- There are about 23 million Flamoth, they have one egg every month, so as long as humanity doesn' get too crazy, they shouldn't drive the species into extinction and make obtaining more Wingjaw items impossible.
- Enhanced Wingjaw steel has twice the lifting force, so a 50-kg person wearing it will float just an inch (I'm guessing here, I'm not a scientist) off the ground. Again, just an FYI.
