Been attempting this clear for months and finally got it done today!
Although Chase’s survivability is bonkers at 2/5, his damage output is too low for the Bar 1 Bruteforce. Unlike Elaine, Chase could only hit on the special side, meaning the fight is over as soon as you make it out of Bar 1. After half bar Cress gains +3 accuracy making it harder to dodge hits, and getting hit twice in a row once Cress gains too many sync buffs could potentially end the run, so use your Kanto Circle to help Chase stay alive during this period.
I took neither Lithe nor Natural Remedy because being paralyzed grants quicker healing and immunity to Poison/Freeze on Bar 2.
