The good thing that I did on this level is i spent extra time on equipment refinement and also all the investment went instead of guild skills all into astrals so i got a lot stronger with BR passing just over 40,000!
And lastly this helped me kill the catacombs level 100 boss without scrolls finally and here below is my last video i think still with 2 scrolls:
And getting stronger also let me join a stronger party for the spire and reach level 8!
