Group
A group is an official party of up to 10 players. To create a new group, you may simply invite the first member (command /invite [player name]) or click "Create Group" under the "Group Options" menu (Esc). If a character is looking for a group, they may let other players know by using the "Looking For Group" option, which will add the tag "Looking For Group" to the character's name in the /who player list and also show an icon above their head.
Benefits
Expeirence and Gold
Being in a group is an agreement to share expeirence and gold from killed monsters or players. Expeirence and gold gains can only be granted if in close range of the event. Expeirence may be capped for players of lower levels who would not normaly be able to kill higher-level mobs. Having a group member that is a much higher level will lower individual expeirence for lower-level characters, no matter how far apart.
Formations
Groups may travel in formations such as ranks or shapes, when the group leader moves, the rest of the group (if in range) will follow automatically. If a member of the group has attacked or been attacked in the last 60 seconds, they will not follow in formation.
Group Chat
Each group member is part of a group chat which can only be seen by other group members (accessable by using /g or /group). Each member of the group is informed when another member loots an item or gold, unless the looter cannot be seen.
Powers
Some buffs may affect a member's entire party at once for easy buffing, and some Area of Effect powers will also exclude group members, making it easier to only target enemies.
