Any advice on how to reach floor 50?

Best advice? Find a fixed group of experienced players with some aetherpool who will speedrun PotD 1-50 with you. That's the fastest way. Otherwise you might be stuck in queue limbo for a long time. The bright side is that once done you can access HoH and Eureka Orthos and probably also the upcoming deep dungeon.
