I can't figure out how to upgrade my fucking sword.
I did the Maw route and get the red sword, kill antoine and ana and get stuck.
I can't find the Mammon.
I tried save where I kill nobody nor the gods.
I tried a save where I kill 2/3 gods but no people.
Each route I get stuck at the vines, whoever upgrades the sword is too well hidden. I found the underground city with tons of cultists, can't kill them. The statue puzzle, you solve it twice, once as the statues in the library show, once in reverse. But I can't find anything in the city of shadows other than the fragment.
I found a place with a fourth fragment but it's gated.
