On the first round of combat a creature may choose to Charge. Charging into combat lets you add your charge bonus to your AC AND to-hit until you either miss an attack OR are hit. This can be positive or negative based on your character's size, as smaller characters are likely to dash themselves on a charge. Mounted creatures get to add their mounts size to their charge bonus. If you do not charge, you have to enter combat by stealth or fire at range until the melee is upon you. Some weapons, like spears, can ignore an enemy's AC bonus when charging, making them better against charging foes.
