The drop rate update is coming tomorrow October 13th. This update is really great for the players that are trying to push new characters to 5*, but for me is awful since they are reducing the drop rate of the rare souls on the time rift dungeons. Right now I have 28 rare souls and I'm planning to spend all my ironite in SoT refills to farm as much rare souls as I can before the update. Are you guys doing the same?
