Most AD&D monsters teach players to hit harder or cast faster. The flail snail exists to break that habit.In this video, I talk about why Gary Gygax included the flail snail in AD&D, what problem it was meant to solve, and why so many tables misunderstood it. This is not a stats breakdown. This is about design intent, spell reliance, and how pressure actually works at the table. Used wrong, the flail snail is a joke or a loot source. Used right, it forces hesitation, planning, and uncomfortable choices.If you have ever watched a confident party freeze when their best option stopped working, this monster did its job.
