Grind

Grinding in the context of MMORPGs is the act of killing a large amount of mobs (often the same types and by using the same tactics) for the sole purpose of gaining experience points and levels, to eventually have access to more difficult quests and more powerful equipment and skills. In most MMORPGs, maximum levels are set very high, so there is often a lot of grinding necessary to reach the top.

Guild Wars is different; the maximum level attainable is level 20, which is easily reached by doing some quests and naturally progressing through missions and the game's storyline.
