If you're unsure, then you have HoT. If you didn't, the story journal would be locked and show a "requires HoT" message with a button to buy it. It says requires HoT, so I'm not entirely sure how I got the deluxe upgrade, to be honest.
Yeah, I meant the gem store. I got the Deluxe Upgrade, I remember it being 2,400 gems. But on the hero story section, it doesn't say whether or not I have the actual expansion.
I bought the deluxe Heart of Thorns expansion through the Trading Post in March of this year, and haven't received anything for it yet. Am I doing something wrong? Is there a way to get gems back if there is no way to access the expansion?
