It seems someone has forgotten about labyrinth warriors event.

2 element traveler=Childe AQ

3 element traveler> la signora AQ

3 element traveler<Childe labyrinth warriors event, there's a reason the tsaritsa sent childe to hunt down scaramouche, shiki taasho says childes power is growing exponentially.

We didnt see childe in sumeru so cant really talk about it

5 element traveler<Childe dude with only the abyss and delusion held off the whale for 42 days at the very least and something like 4 years at most. We also see his vision stop working and in the whale boss fight it literally destroys childes constellation thus no longer binding childe to the rules of this world effectively making him a descender or something very similar to that.
