Im having an npc ask player to chose between 3 versions of an item. Like this:

Which element whould you like it to attuned to?

Fire Frost Thunder

This choice is not intended to be repeatable.
Then have the game pop an item into player inventory.

This might get you started:

So i have to set variables to the npc first, then ask? Ill try that..
