Best route as ???

[Moh]

What regions should i go to as inv? I have got the echo in Shaded Citadel and have gone to Industrial Complex

FP wont help you with karma when you get to him, so maybe try going trough chimney canopy, sky islands and then farm arrays to get full Karma and be able to ascend.

Do you even need karma as him? Can you just kill the guardians with his bombs?

I beat ???. I decided to go to chimney canopy to get the echo there then go back to industrial to outskirts to farm arrays to subterranean.

The only big pain in the playthrough was farm arrays but i am assuming there isn't really any other good route cus you have to either get the 4th echo from the sub's entrance from farm arrays or go to sky islands but i imagine sky islands is going to be terrible.
