B/X D&D’s three-alignment system — Law, Neutral, and Chaos — is the original 1974 alignment system Gygax and Arneson shipped with, restored by Moldvay and Cook’s 1981 Basic/Expert rules after Holmes’ five-alignment patch and AD&D’s full nine-alignment grid came and went.

Everyone assumes B/X only having three alignments — Law, Neutral, Chaos — is the stripped-down version of Dungeons & Dragons. It's the opposite. Three alignments is what Gary Gygax and Dave Arneson actually shipped in 1974, built on the Law-versus-Chaos cosmology of Poul Anderson's Three Hearts and Three Lions and Michael Moorcock's Elric novels. Good and Evil didn't show up until 1976. Holmes' 1977 Basic Set grafted on an unfinished five-alignment patch. AD&D's 1978 Player's Handbook finished the full nine-alignment grid everyone pictures today. Moldvay and Cook's 1981 B/X went back to the original three — and this video walks through the actual rulebook mechanics (alignment languages, reaction rolls, Protection from Evil, Know Alignment) that prove three alignments still does everything nine never earns its keep doing.
This video is one leg of a three-way, independent-takes collab — no rebuttals, just three OSR creators making their own case for their preferred alignment system this week.

![B/X Green Slime Done Right: Why Most Rescues Get Someone Killed
How to run Green Slime in Old School Essentials without killing the rescuer: Moldvays 1981 Basic Set made it a trap, not a monster — and most dungeon master tips get it backwards. This old school essentials breakdown covers the 6-round armor rule, why attacking it fails, and how to run green slime RAW.
Green slime doesnt kill your party in B/X D&D — the rescue does. The 1981 Basic Set built it as a biological trap, not a combatant, and the stat block proves it line by line.

This one goes through the Moldvay B/X Basic Set entry on green slime — the Armor Class rating that admits it has no defense, a Move speed that means it can never chase a fleeing character, and the two rescue instincts (hit it, pull them free) that turn one victim into two. Also covered: the one detail in the entry almost nobody plays — the six-round gap between cloth dissolving and metal dissolving — and why Moldvay bothered giving a mindless ooze a Morale score it will never use.

[00:00] Intro: The Real Danger of Green Slime
An introduction to why its not the slime itself that usually kills characters, but the panicked rescue attempts from the rest of the party.
[01:41] Green Slime Stat Block Analysis
A deep dive into the creatures stats. With no defense and virtually no movement speed, it acts as a stationary hazard rather than a traditional monster.
[02:36] How Green Slime Attacks the Party
Because it cannot chase characters, green slime relies on the element of surprise, waiting for an unwary party to walk underneath it.
[03:26] The Gruesome Effects of Green Slime
Once it touches flesh, the clock starts. You have a very limited time (about one minute/six rounds) before a character is permanently turned into slime.
[04:08] The Only Cures: Fire and Cold
The book outlines the specific ways to stop the clock and survive a green slime encounter, which almost always involves burning it off with a torch.
[04:31] The Armor Rule Everyone Forgets
A crucial, often overlooked detail in the rules: wood and metal (like shields or gauntlets) buy you six full rounds of time before the slime ever reaches the flesh.
[05:26] Instinct 1: Why Attacking Green Slime Fails
Why drawing a weapon and swinging at the slime is a terrible idea that only puts a second party member in danger without doing any damage.
[06:02] Instinct 2: The Danger of Pulling Friends Free
Why trying to pull a friend free bare-handed instantly turns a single-character crisis into a two-character problem.
[07:28] Why Green Slime is a Trap, Not a Monster
Analyzing the Number Appearing, Treasure Type, and Morale stats to prove that green slime (like the gelatinous cube) is an environmental hazard meant to be avoided, not fought.
[08:53] How DMs Should Run Green Slime Encounters
Advice for Dungeon Masters on how to deploy green slime at the table to test your players instincts under pressure.
