Player: I rush across the room and hit the orc with my sword!"
DM: Whoa, slow down there, shorty. Now how far is it to the orc? Count the squares.
Player: Oh, uh, okay. [Counts] Looks like 12 squares.
DM: At a scale of one square equals five feet, that's 60 feet. You can only move 30 feet and attack, unless you take a charge action. Do you wish to use a charge action?
Player: Uh, sure.
DM: Be advised, however, that if you use a charge action you will suffer an Armor Class penalty until the end of the next melee round.
Player: Okay, fine. (Sighs, tries to get back into the spirit of the game) I charge!
DM: You enter a threatened square. Although the orc is ten feet away, he has a longspear with reach. Thus he can strike you with an attack of opportunity if you leave this threatened space. Do you wish to leave and continue your charge?
Player: (Sighs deeply) Sure, why not?
DM: (Rolls some dice) The orc strikes you with his longspear as you leave the threatened square. He has the Expertise feat, meaning at his discretion he can subtract his Base Attack Bonus from his attack roll and add it to his damage roll. You take (rolls) 8 points of damage.
Player: Okay, fair enough.
DM: Well?
Player: Well what?
DM: You continue your charge, right?
Player: Oh, was I still charging? I had forgotten. (Pauses, looks around at the group) Say guys, do any of you feel like playing Betrayal at House on the Hill?
