Not sure if this a bug or intended, but it feels a bit weird – currently the base XP or Gold you gain is calculated against the total. When I get an Atlas of Adventure for 15000xp I expect it to give me 15000 additional xp, but it currently gives me only 10000, as it is considered to be fulfilled when I’ve gained 5000xp + 10000 additional xp.
I’ve reported this to support as well and in-game support told me this is behaving as expected.
Which either means it was intended, or it’s a bug they won’t fix.
Ok, thanks Lan. XP books feel low for their cost currently so I skip them, and Gold books I buy only for Heroic Challenges or Secret/Personal rooms anyway.
