Opening Text for a Knight - The Knight is the easiest character for the new player to use. A good Knight should have plenty of strength, as they specialize avalon gold in battling an opponent with their sword.

Knights are the fiercest warriors in Lineage, with more strength than the other classes. In addition to this, they have the ability to use more armor and weapons than any other class, making them quite effective in both giving and absorbing damage.

Just make sure that your weight does not go over 50%. I would suggest picking up or sending yourself as many letters as you can since they don't take up much if any weight. You will want a lot of these, probably around 70-100.

You are probably thinking that this sounds really stupid, but here is the point. If you are not full lawful (32,767 alignment points) and you die, you will drop an item from your inventory.

By carrying so many letters, you will usually drop a letter rather than the important item you don't want to lose.

Note that this does not guarantee that you will drop one of the items you want; it just improves the statistics of you not dropping it.
