Answer to the Question!
Hello! I gave people a few days to answer, here is the actual list. The number shown on the far right of the picture is the number of spawns the monster has. One of the issues people had in their guesses was they combined monsters that are actually separate entries, like DVC succubus vs TOI succubus. Dinin did include ants, which by a wide margin claim the #1 spot with 462 spawns. Cruel Snow tigers come in at #2 with 298, followed by Cursed Elmore Soldiers at 250. In general a lot of TOI monsters are on this list, especially ones that spawn across almost all of their set of 10 floors. Some surprising ones on this list, at least to me, are dream island killer bees/ball lightning. Those are a lot more dense than I would have guessed. A lot of low level monsters like Arachnevils, Spartois, Skeletons, and Zombies are all in the top 30, but I think they lose out because they just don’t spawn with the same density as many monsters in more dangerous/higher level areas so even though they occur in a lot of places there are not that many of them in each place. Deer still come in pretty high, although I will likely remove them for server load sake. I double checked and Sea Dancer is the one record on here that isn’t accurate. It only has one spawn, so I don’t know where it’s getting the 133 number. It’s a mystery we will have to look into.
Hope you found this interesting!
