The script attached to this event fires when a client leaves the module. This can be used to remove any custom creatures spawned because of the appearance of a particular PC or a variety of other things.
Whenever a player logs out of a server or leaves the module. This event doesn't trigger in local/single player game at all.
GetExitingObject() returns the PC who is leaving.
Triggers before player exit an Area and in case the player is dead, area's OnExit event won't fire at all. For more info see OnExit.
Otherwise this in NWN:EE works as expected and you can retrieve and save information from the client/character as they leave for later use. Note you cannot add/save to the character during this (without workaround, See EE Note below)

During this event, the player has already left. All data that pertains to the player is unavailable (GetPCPlayerName, GetPCPublicCDKey, GetPCIPAddress) and the player has become detached from the character object, hence GetIsPC returns false. If you want any of this information at time of client leave, you must have already stored this information (on client enter is a good time to do this). Also, due to this, no locals can be stored on the PC at this time. If you want to store information pertaining to the player during this event, store it on the module with something to indicate which player and character it is for.
You can't get any information off the GetExitingObject(), which basically means you can't store, for example, their location, and get it locally - SetLocalLocation() and GetLocalLocation() respectively. Some information is however still accessible, namely: GetName, GetLocalInt, GetLocalString, GetLocalFloat, GetLocalLocation (this list is not exhaustive). However, while data can be accessed from local vars, setting local variables in this event doesn't work. To work around it, you need to set local variable on the module with the player ID / name as a part of the variable name, i.e., SetLocalInt(OBJECT_SELF, ObjectToString(oPC) + "_exited", TRUE);
GetPCPlayerName doesn't work properly during this event; GetExitingObject does not return an object that can be saved to the database. See above for reasons, and the other functions that do not return data.
The bugs related to this script firing are fixed; OnClientLeave event is now called before the creature is physically removed from the area, instead of after, to allow scripting to determine the creature’s position as it leaves. However, OnClientLeave event is still after the automatic server call to save the Character file. Therefore if you add items or save local variables during this event be sure to call ExportSingleCharacter explicitly before the event end.
// NPC) still exists, but the PC's properties do not.
// In this example, we know GetName will work, such as a
// characters name "Hero". If we used GetPlayername(), it
// wouldn't return a valid string, merely "".
// Other things that would be useful might be GetLocalInt(),
// GetLocalString(), GetLocalLocation() and so on. These might
// be stored to the database, for example, for when they re-log
// into the server next time.
// Valid data we could use:
object oPC = GetExitingObject();
// If they have an item, of tag SHOUT_EXIT, we shout to the
// world we have exited. As it is the module shouting, it should
// appear as "[SERVER]" as the shouter name.
