So there's a pretty common idea that Dragons can breath fire through some kind of biological napalm, but what about White Dragons? Is there some kind of biological way to spit something that freezes things?
Also post other ice monsters.

It'd need to internally create two chemicals that have an endothermic (exothermic? I can never remember which of the two means "sucks up heat") reaction when mixed, store them separately in its body, then spit both at once. Kind of like a frosty version of the bombardier beetle.
>>47646100
This an ice thread, I bet these monsters are chill
>>47646100
Could it be as simple as spitting liquid nitrogen?
>>47646179
Endo draws heat from its enviroment and heats up, exo the solution cools but heats up its surroundings. Unless the creature can move the heat given out from an exothermic reaction to an exhaust vent or somesuch and then expel the solution, it's impossible.
Look at a fridge for example. In a fridge coolant is turned into a vapor within the piping where it absorbs the heat from the inside of the fridge, and then moves to the back of the fridge where it's condensed, releasing the heat it gained from becoming a vapour. Heat is moved from the inside of the fridge to the vents at the back.
such a creature would find using the heat it needs to vent a more potent weapon than the substance it's trying to cool

How would you store it?

Rapidly expanding gases. The dragon would be a fucking bomb walking though.

You could do the same thing, but instead of an incendiary, it's liquid nitrogen, or something similar.
How you could feasible store liquid nitrogen biologically? Magic.
The problem is fire is more destructive than equivalent heat. So you cant just invert it and make an ice dragon and expect something dangerous.
>>47647087
who says it has to be destructive? It kills tissue and impedes movement, but it's not got to destroy forests or anything
>>47646795
so, what, like there's a supercompressed pouch of freezing gas that it burps out?
What are some monsters that I can put in my magic ice wasteland?
I already have mammoths, ice dragons, and ice warlocks.

Five meter tall Yetis. They have the muscle mass of a gorilla, claws as tough as steel, and a almost magical ability to navigate through snowstorms.

OK how about this? The beast stores compressed air in its body. Compressed so tightly it becomes a liquid.

-thermic reactions don't just shuffle heat around between the reactants and the environment for no reason. First the solution's temperature changes due to the new chemical bonds using different amounts of energy than the old ones, and then thermodynamics make the solution absorb (for endo-) or reject (for exo-) heat to balance out.
So, yes, an endothermic reaction WILL make the things it's in contact with colder. There just aren't that many particularly strong ones we're aware of.
I want to make ice zombies
how can I make mutations that would simulate ice powers
>>47646100
Given you know about the dragons, I'll assume you are a scholar. Therefore you should know about the basics of what the world is made of. Thus, we can forgo long-winded theoretical explanations and simplify the dragon's breath to a stream of particles made of elemental air and water.

No. Heat flow is not a chemical reaction. Heat flow is function of thermal equilibrium. Endothermic reactions consume heat to occur, there is no stipulation where the heat comes from, and the reaction ends if the available heat is exhausted. This can be something like the mixture freezing if it is isolated from other sources of heat.

A specific way this could be achieved by a dragon would be through the endothermic reaction of ammonium chloride, which is found in nature (in volcanic regions) and barium hydroxide, which can be synthesised from nature. Barium hydroxide can be formed by the addition of water to barium oxide, which is formed by heating barium carbonate which is also found in nature (although admittedly not in volcanic regions). Even if the dragon would have difficulty heating the barium carbonate to the appropriate temperature it could force the reaction through the use of catalysts / enzymes, and by constantly removing carbon dioxide from the bladder (a standard biological process) containing the barium carbonate, shifting the equilibrium towards the barium oxide state. The resultant barium oxide could be filtered out by flushing the bladder with something like ethanol which dissolves barium oxide, but not barium carbonate. The dragon may also be able to supply heat to the mix by entering a hot spring or other volcanic nicety.
>The dragon could store the barium oxide dissolved in ethanol until it was ready to release its freeze-breath, at which point it would pump water into the barium oxide, which would rapidly precipitate out of the ethanol as it became barium hydroxide, which is mostly insoluble in ethanol. Barium hydroxide octahydrate is a crystal so the remaining ethanol and excess water mix would help to flush the slurry into the ammonium chloride bladder. This mix would then be expelled rapidly into the atmosphere. The mix will cool to ~-20°C (depending on volumes), which is enough to freeze most animals. As a side benefit you also get a strong smell of ammonia, which is very atmospheric (no pun intended).
That one sounds pretty good. Is there a way that could be liquid instead of a powder though?
why are ice/mountain creatures always "huge"?
Shouldn't ice creatures be smaller due to the lack of food?

>Science fictions inspire scientists to create the freeze ray. Lasers usually transmit heat to the object, but scientists had found some cases it can absorb energy in an object and decrease its temperature(2). A carefully tuned laser can chill an object by dampening its molecular vibrations, causing the object to shed energy as fluorescent light. The laser works the same as the freeze ray in science fictions, which makes an object to quickly decrease in temperature. Scientists call this technology Optical Refrigeration, they did not transform the technology into a weapon but incorporate it to create other technology. Optical refrigeration can help in the advance of many other technologies. A simple application would be allowing computer makers a simple way to cool their machines' hardware, making possible faster and more powerful circuitry for computing and communicating
Organic lasers?

Square-cube law at work. As the size of the critter increases it has more internal volume (with which to heat itself up) in relation to its external surface area (through which the heat escapes). The colder the environment the larger the "minimum" size needed to avoid freezing to death.
