Diablo III Prime Evil Wings: Diablo II 20th Anniversary Reward
Diablo III players who login during the Diablo II 20th Anniversary (June 29, 2020) will be greeted with a Feat of Strength: Primeval Evils Achievement that rewards the Prime Evil Wings. (thanks, Ivenend)
The wings look like Baal's tentacles -- in reference to Diablo II: Lord of Destruction where Baal corrupted the Worldstone.
