A higher Legendary drop rate
Were you planning on playing Reaper of Souls this weekend? Well you might want to reconsider if it wasn't in the cards, because Blizzard has added a special buff for everyone that will be playing Diablo III in the next week.
Starting today, players will receive double Rift Fragments, and a 100% boost to their Legendary item drop rate. The event kicks off on Thursday, May 15 at 12:00 a.m. PDT and ends on Thursday, May 22 at 5:00 a.m. PDT, just to be clear.
Happy Birthday Diablo III [Battle.net]
