woooowwww. Today, with AD&D as firmly lodged in the past as outrage about Cyndi Lauper's "She Bop," someone pointed out ANOTHER thing Gary did to FUCK OVER PLAYERS. It's the helmet rule on page 28 of the DMG where I apparently missed it for DECADES.
@CoyoteTraveller commented over in Discord, but there's a rule about helmets I'd missed because it's one tiny paragraph in the DMG -- they don't automatically come with your armor, you have to buy them, and if you're not wearing a helmet, you're far more likely to be hit/targeted in your AC 10 head.
@Leucrotta What's that?
