Not to be rude but YOUR chance of soloing it is incredibly low, it takes a ton of time and skill. The first part anybody can do because of a cheese, then conflux that is incredibly hard also might not be possible since the g horn nerf, oracles honestly I don't know if it's ever been soloed but if so I'd image it'd take time to learn the spawns then actually be able to kill them all, Templar is possible but fairly difficult. Gate keeper is up next and that is by far the hardest part that has never been done so this is the main reason as to why you can't. Atheon is not to hard just have to get to the spot up top and snipe with ice breaker.
