I have spun the wheel of Yogg at least a dozen times, and I have pulled every result multiple times as well. I have also tossed a minion at my opponent for lethal damage with Maxima, yet neither of these achievements have triggered. I’m very close to level 25, and the xp from these would tip me over the edge, but I can’t get them.
In which game mode? XP-rewarding achievements do not trigger in Casual.
