For me, the most misunderstood rule in my early days of roleplaying was Hit Dice or HD in AD&D. Here's why:
When my parents got me my AD&D books for my birthday way back when, I was given the Player's Handbook, the Dungeon Master's Guide and a set of dice. Notice something missing? Yep, the Monster Manual.
Not having the Monster Manual wasn't that big a deal - you had monster sumaries in the back of the DMG. Everything was listed, including HD. Not knowing what HD actually was, I assumed it meant Hit Points for Denizens or something. So, Orcs had 1 HD or 1 Hit Point. Ogres had 4+1, which was a silly way to saw 5 Hit Points, but who was I to argue.
Yes, those early days had monsters that were quite the pushover.
So, what rule or rules were your most misunderstood rules back in your early days of gaming?
