Create a party with up to 7 other players and fight as a team. As your party fights as a team, the Party Level will increase. To party another player, select their character then use the 'Party' skill found in your Skill window. Use the shortcut ALT + S, or use the menu.
EXP Division allows the party leader to divide the Experience gain up by equal share (each party member receives the same amount), distributed by level (the highest level will receive the most, followed by the second highest level, and so forth) or disabled completely (party members only receive experience for the monsters they kill themselves).
Item Earning Priority allows item drops to be set as Equal Loot Distribution -- when a party member is dropped an item, it belongs to them -- or Acquisition Order -- any party member can pick up an item drop, and it is given to the next person due to receive a drop.
Once a party is formed, the Party Level will start to increase as party members defeat monsters (PvE).
Party members will receive 1% extra experience from defeated monsters for every Party Level, up to a maximum of 50% extra (Party Level 50).
