Early floors are pretty easy to solo as a paladin, but the problem that really struck me was actually the time limit. At the higher floors it's really going to be difficult to solo, in my opinion if you want to solo, you basically have to solo the earliest floors until you max out your armor/weapon, then go to the next floor, repeat. But it may just be too difficult to do because of how high the damage is and the dungeon doesn't scale.
