This happens with the Skeleton Template, which is present in three homebrew books from the selection. If there's a homebrew monster that has the same name **and** the same concept of another homebrew monster, they both get added to the list, but with indication of where they're from. This happens with the Siren from the Book of Beautiful Horrors, whose name gets changed to Beauty Siren, because there's already a Siren in the Tales of the Yawning Portal.
If there's a homebrew monster that has the same name **but not** the same concept that an official monster has, its name gets changed a little bit. As an example, this happens with Demogorgon and other Demon Lords/Princes present on the Epic Monsters statbook, as they already are present in either Out of the Abyss or Mordenkainen's Tome of Foes. If there's a homebrew monster that has the same name **and** the same concept that an official monster has, it gets excluded out. They are not properly stated on the spreadsheet though, because it's a lot of work adding the monsters as they're multiple PDFs and images. These guys have been making a monster every day of the week (except saturdays and sundays) for about 2 years now, so they've surely learned to do this right. The only exceptions to this rule are the monsters from r/monsteraday. If we ever need it, I'll have a sun (❂) symbol ready for 2500 upvotes, but it's kinda hard to get to this score. Each star (★) means 100 upvotes and each moon (☪) means 500 upvotes. With this, every source link has a score indicator next to it. This results in some relatively bad content passing through, and some really good content falling behind, but if you've got a better idea, please do tell me. I've only included monsters from posts that have got 100 upvotes or more, here on r/UnearthedArcana and on other D&D subreddits that discuss about 5e ( r/DnD, r/DMAcademy, r/DnDBehindTheScreen and r/dndnext ). In a world where some homebrew content can be shitty, I felt the need to exclude some of them. (This can also be found on the search sheets)Ībout the homebrew monsters, I've decided to make a little.
As an example, if I want to search monsters that are immune to fire damage (and there's a lot of them), I just type in "fireimmu". To track the Weaknesses, Resistances and Immunities, I've made a little "system" in which you search the type of damage or condition, and then add a "postfix" to it. Well, now that they're made, I ain't removing them. I created auxiliar sheets for searching and listing specific words within the main sheets, but figures you can just Ctrl+F the thing. With this, we end up with 797 official monsters and 1890 homebrew monsters. With this, you can find and compare monster stats however you like! Complete with all the official stats (except named characters, which I'll be adding later) and some homebrew stats (which I'll explain in a moment), including: Name, Size, Type, Alignment, AC, Average HP, Speeds, Ability Scores, Ability Score and Skill Modifiers, Weaknesses, Resistances, Immunities, Senses, Languages, CR, Traits, Link to Source and Author.
