Fox Constellation

I finally got the Fox Constellation, but I haven't finished the story yet, so I can't farm echoes. I'm trying hard to clear the story now, but it's really boring because the previous one was Lahai Roi... Lahai Roi was almost all fun, but I already miss Aimes.. ㅋㅋ Rinne too.. Monie too... Still, I have to farm echoes for the Fox Constellation, so I need to push through the story. I'm running hard from Act 2 of Chapter 4. After getting the Fox Constellation... I finally saw the Fox Constellation in the story too..
