Fall damage is inconsistent in Minecraft and I hate how it works. So I made a precise formula for how to calculate it. Keep in mind that a lot of what I say are just speculations and I can make mistakes once in a while, or just have no idea how something works. Like the TNT negating more fall damage on higher difficulties, which made absolutely no sense, but that's just Minecraft and it's spaghetti code. I know the game quite well from the technical side and there are many weird anomalies happening occasionally, which is why I do this series, where I explain them. So check out my other episodes.
