Huge robes! source This is why wizards wear those giant robes. Also giant hat (hers is in the wash) and giant beards (also in the wash). By inflating their volume with nonmeat bulky clothes, they will have a larger cavity in the wall inside which to maneuver. Under the bulky robes the wizards are quite spindly. They can hunker down within their bulky ...

Employ mermaid escorts. They are smart. They like stuff we have because they accept it in payment from ships crossing their territory. Presumably they can deal with criminals of their own kind. Mermaids associated with the area in question accompany boats. They ward off rogue mermaids whom they identify by their ruddy complexions. The mermaid escorts (...

They are safe. A 1000lb medieval crossbow has an initial velocity of around 150 fps (~45.7m/s). Oddly increasing the poundage of the crossbow does not increase the velocity just the allowable weight of the projectile, the distance traveled by the bowstring and the speed the bow can flex act as limits. I will use the the formula for firing straight up because ...

It's complicated Start by forgetting pretty much everything you have seen in movies or the majority of computer and table-top role playing games. Movies and computer games concentrate on flashy visuals while TTRPGs focus on playable rules. Real life is more complicated. Bows can be classified in various ways - by draw weight / purpose, by configuration and ...

Let's first establish the differences between some of the reasons your character might have passed out. Exhaustion: Working hard doesn't really make you lose consciousness on its own, but depending on other factors it can contribute to one of the others reasons you might pass out. A physically fit person who is properly hydrated and not overheated can ...

Forest fires are a type of wildfire, which to spread effectively need at least two things: Sufficient dry starting fuel. Wind in the direction of spread. If constructed correctly, it is conceivable that the non costal side of the forest would not experience a sustained wind coastwards, but would experience a sea breeze, pushing the fire front away from ...

By farming it. Leave the natural forests alone, and plant your own tree farms, just like we do for Christmas trees and paper. For firewood, staves, bows, wicker, and small beams, use coppicing to increase year-to-year productivity, and otherwise just keep a rotating field. If it takes, say, 20 years to grow a tree suitable for milling, and you need to mill ...

Cholera. If you want to emphasize methodical scientific method you could do worse than to copy John Snow, one of the founders of modern epidemiology. 150th Anniversary of John Snow and the Pump Handle John Snow, M.D. (1813--1858), a legendary figure in epidemiology, provided one of the earliest examples of using epidemiologic methods to identify risk for ...

You can give birds medieval levels of technology, but they will not fight excatly like medieval armies The sky would become the preferred arena for birds to fight wars in because "high-ground" is so important to the way birds fight when trying to kill something. Attacking from above gives a bird a better attack speed which translates to a more ...

Scurvy. It spreads mostly in ocean going navy, but not necessarily. The time traveler kind of suspects the disease, but does not remember the symptoms (can you?), apart from teeth falling out. He also knows the cure is vitamin C, and definitely knows that lemons (or similar) would be very good, but... there are no lemons. Nobody knows such fruits when ...

The trees are fireproof. The elves do not live in forests of lodgepole pines. Or maybe some used to but moved out when the forest burned. They live in redwood forests. http://forestschoolsbapet.blogspot.com/2013/04/redwoods-and-why-are-they-fireproof.html Why is the Redwood tree fireproof? Redwood trees have very thick bark which has a lot of water ...

Location location location. Make yourself such a hard target no one wants to attack you. The problem with an army is that they come from the population, especially in medieval times. Losing too much of your army means you lose the war, and even if you "win" the impact on your country can be so large that you choose not to fight certain targets. ...

I'd say in less than 2 months he will learn how the base system works and manage to fend for himself, and in less than 2 years he will be indistinguishable from a normal future person. Humans usually learn vital things pretty fast. A rich CEO in another country might never learn the local language, they don't need to. There are plenty of rich foreigners in ...

I believe that you may be asking slightly the wrong question. You ask: "Will Ships still be useful on a super-continent" To which my answer is .... Yes! But a slightly better question is: "Where will trade occur, and through what means" Curiously, predicting trade is often a fairly good proxy for technical prowess and societal development ...

Wizard instructors learn wall extraction techniques the way swim instructors learn CPR. The trick is to locate the cocooned caster and get some air to them. This is done through a combination of three spells... Association - take a small piece of the stone pillar which has switched places with the victim and scry its magical congruent, tracing its ...

Ravens! Just as blind people can be given a well-trained guide dog, those who cannot speak can be given a trained talking raven. In your scenario, this type of raven has been bred over centuries to be the best possible of mimics. They are trained from an early age to recite incantations in response to hand signals. The requirement of magic is that the voice ...

Being exposed to and be able to speak a certain language is one of the conditions for triggering the magic in the bearer. Local language influences the type of magic that can be used, because each magic type requires specific sounds to be triggered/activated. And it is also the case that close to the border people end up knowing both languages, and that when ...

Nonsense. If something is allowed by the law, then it is not a crime. The very definition of a crime is breaking the law. The proper question would be why the law in this city is more lenient than elsewhere. Consider for example the US, which is probably the country with the most legally heterogeneous country in the world. In some places you can walk around ...

Dutch started building dikes from the Iron age. The earliest indications of dike building date from the late Iron Age. During excavations of terps in the Frisian villages of Peins and Dongjum, among others, dike bodies were found – small dikes predating the building of the terp. These little dikes, no more than 70 cm high, were composed of neatly-stacked ...

Even if the balloon flies low enough that you can actually hit it with a crossbow or longbow (and it is surprisingly difficult to aim at a moving object above your head) you won't do much damage. First of all at the top end of its trajectory the arrow or bolt won't have much penetrating power left. And you will mostly be hitting the bottom and sides of the ...

Wool Historically specialized* fire fighter clothing was made of wool, with leather only being used anywhere wool would not work (like hats). Even today wool is uses in a lot of fire fighting equipment and is consider one of the best available materials. It may sound strange but wool is actually very fire retardant. Ignition temp 600°C, leather on the other ...

I guess the Pied Piper of Hamelin came out of this school. The trick is being able to find a translation of the spell which works well when it is casted by playing the appropriate sequence of notes in a musical instrument, be it a piper, a flute, a harp or any other instrument with a sufficient extension. Once the key is properly played, the spell is ...

Local Deities Centuries ago each country used to worship their own deity, these deities were in competition with each other and have the ability over certain powers, just like greek mythology, So each of them presented a boon to their worshippers to bear these specific powers to compete, over time, the competition is over but the fraction of boon still lives....

You probably don't hold the Village I like KerrAvon's answer a lot, but it mostly discusses bow technology. I'd like to address the tactical side. It's a pretty tall order to defeat an enemy that outnumbers you five to one — and if any of the 200 villagers you mention are children or old people, the odds get even worse. Even if this village is compact, it's ...

In a broader sense, defending the forest is not just "prevent any tree to be cut", it's "ensure that the trees are healthy". Therefore they get wood by practicing sustainable forest management. For every tree they cut down they plant a new one, and they make sure that they keep healthy forests. This fits under the behavior of the creature ...

The Elves won't stop you because they are already setting fire to the forest. Forest fires are a natural part of many forest's life cycles and can actually be beneficial in controlled burns. Letting a forest grow too long can lead to the next fire being to dangerous or affect forest health. So long as the trees have a fast life cycle it may be hard to ...

Words aren't important It was never about the incantations but the mindset formed saying the words. In the Marvel Movie Doctor Strange, Strange says to the Ancient One he can't cast due to the injuries to his hands at which the Ancient one shows him a caster missing a hand completely. Magic is all in the mind. Incantations, mystical ingredients, hand ...

Melee Weapons -- Shield and Teleport The era of gunpowder is also the era of the pike-block and cavalry charge. Cavalry beats musket; Musket beats pike; and pike beats cavalry. The reason melee disappears is because firearms become so effective that that cavalry is no longer a counter. Once cavalry disappears, there is no need for pike blocks. So all melee ...

Pre-modern cities in general needed massive amount of farmers working elsewhere. The safe calculation is that urban population can be only as big as 10% of total population, which mean that your 10mln man city would need 90mln people producing food. Now to put it into perspective, ancient Rome had around 1mln people and even though essentially entire ...

He will say: "Oh you're obviously from far away we don't have clothing that nice" There will be a lot of variation in the response depending on exact time period and location, which hasnt been given exactly. Appearing in 1200ad in Rome, China, Australia, America, Egypt, Turkey, Russia, etc will all have wildly different outcomes. Even the precise ...
