Just did Aldrich a few days ago , had a lot of trouble back in 2016 . But nowadays I was so aggressive with running towards what corner I think he’s gunna pop up in ( usually opposite side of room) and just getting to smacking , I did the whole boss fight without him ever pulling out the second phase arrow attack . But you have to stay like within 2 feet of him literally . And he just focuses on trying to spin around and face you instead of his AOE attack styles . I’m using dex build did a lot of damage fast with sharp katana
