New D2 player, so I didn't quite understand that the season pass for the Undying came with the regular and deluxe versions of Shadowkeep. Is there any way to pay just an "upgrade" fee to get Shadowkeep? I was hoping it would work like some other Steam bundles where if you own part of a package it would discount it, but I don't think the season pass works that way. Is it possible customer support would help? Or am I just going to have to eat the cost and pay for the season pass twice? Any help would be great, thank you!
