My quests are going great (Thanks for the help!), but I have an issue now.

Once a player completes one of my nonrepeatable quests, the NPC still offers them the quest. They can accept the quest only to find the book says it is not repeatable.

I have confirmed that the XmlQuestAttachment is being added to the player and all that is working correctly. I just need to add a condition to the QuestNPC so that he does not trigger his speech if the player has the attachment.

The NPC already has a NoTrigOnCarried set to the name of the questholder (so he doesn't ask them for help once they already are on the quest). Now I need something similar to prevent the offer if they've completed it.

Thanks!

add something like this to your NoTriggerOnCarried bar:

so if you already have the name of the quest holder it would be

Questholder | ATTACHMENT,Quest Name,XmlQuestAttachment

ie

Kill Bobo | ATTACHMENT,Kill Bobo,XmlQuestAttachment

That will check to see if the player already has the attachment, and then won't trigger if he does have it.

Perfect. works like a champ. Thanks!
