Kill Every Monster starts from a blunt premise about Dungeons & Dragons: the game rewards players for killing monsters, so which creatures actually deserve the name? Each monster episode takes one classic creature and puts three questions to it. What is it? Is it really a monster? How would you change it? Dylan and Aram co-host, and a guest joins them for the discussion before playing the creature in a one-shot actual play. Most of the opinions come out in the discussion. 'Yuan-Ti' shows how far that discussion can range. The conversation picks at how the game files its creatures, with some forms listed as monstrosities and the pureblood as a humanoid, and asks whether one of them eating a person is still cannibalism. Taxonomy is hard, as one voice puts it, and harder in D&D. The same episode argues that imagery in a creature's design should serve a purpose, and that designers should consult the relevant people instead of treating it as decoration. 'Gnoll' is more tactical. Gnolls moving in formation mean an ordinary battle; a mob charging all at once means a worse gnoll is somewhere and it is time to leave. The redesign idea there is a desert society that reveres the dead, closer to an Anubis-like take on eaters of the dead. 'Rust Monster' sets a scene in a small dwarven mining operation, where an emergency call comes in during a major excavation. Not every entry is built around a single creature. 'Season 3 Mailbag' and 'Season 4 Mailbag' also appear in the feed. The latter argues that the Tarrasque's real problem is boring design, not that it cannot be killed, since anything with stats can be killed. 'Dylan Is Mad About A Thing 001 - World Building' turns to regional magic: kingdoms blessed by particular gods, and characters who all arrive with a small spell from home. The tone is loose and blunt, and the language can get salty. In a running bit, Aram announces he has found a very clumsy dragon and Dylan insists dragons are not real. The bit leads into the Patreon pitch, where one of the perks is audio notes from the two of them on how each episode was made. The show describes each episode as a self-contained story, so the monster that sounds most interesting is a good place to start.
