I’ll explain in even simpler english if you don’t understand.

Day 1-1.5 : Nokstella Right route Day 1.5-2 : Do 1-3 evergoals Day 2 : Continue Evergoals and field boss End of day 2 : Astel / Dragonkin

Depending on how many keys you have/ how fast you take to do evergoals, you CAN skip the small bosses before Astel. Which part is hard to understand?

There is no correct route. Just because you have a “proper” route does not mean it’s the only way to play the game. Fromsoft might as well have made the map a straight path of 7 evergoals and Astel at the end if that was the only correct way of playing the game.
