This thread is not about the abuse of rules, but rather the misunderstandings of how rules are properly used.
Here's the kind of thing I mean. In our 1e days we didn't understand how xp was rewarded. We thought that the xp went to the person who killed the monster and that treasure based xp was based on who got the treasure. So we had situations in which our fighter would dish out a lot of damage, often reducing the monster to one or two hp. Then the mage would use a dagger, sling, or magic missile and deal one or two points of damage, killing the creature. That meant the mage often got the xp. But in order to get around that kind of thing the group decided to fight defensively in order to take turns getting the xp reward. It took us several months to find out that xp rewards was shared equally among the characters, as long as they weren't knocked out of the fight.
For 3e, our DM initially thought that the Base Hit Tables in the classes were added together instead of incremental increases. For example, he thought that a +1 bonus to hit at 1st level was added to a +2 at third level for a grand total of +3 instead of increasing by +1 to +2 for a total increase of +1 to hit.
So what other misunderstandings of the rules for any edition have you come across?
