Only the aoe type spells are implemented for this targettype, spawning things at the X Y Z location is not handled currently.
If you want to do custom stuff with it though... try using...  "GetTargetRingX , GetTargetRingY, GetTargetRingZ" and spawn the specific pet or totem with perl :p
	Code:
	sub EVENT_CAST {
	if($spell_id == 16938) {
		quest::spawn2(26044, 0, 0, $client->GetTargetRingX(), $client->GetTargetRingY(), $client->GetTargetRingZ(), 0);
	}
}
 Can use this to "place" NPCs with a spell.. for something like a "totem" or whatever, and then have the totem pulse a spell to all nearby players to heal or buff them.. ect ect
