Hi all, just did path 3 in abyss for the Carina's challenger and have produced a rough overview of item spend for anyone interested. Never got round to doing this as the collector is such a BS fight, and put me off. Abysmal fight design. BS evade and unstoppable, combined with tenacity is a nightmare. Sometimes collector would just throw a full combo into my block.

I played decently and got the path down in 5 revives; if I was playing slightly better and got a bit luckier I think it is possible to do this path in 2 revives with this team. Screw the collector, it’s a bad time and a revive fiesta whatever you do. This challenge would have actually been fun if he didn’t exist.
I have a full guide with screenshots and detailed fight by fight tactics if people are interested, but I imagine most people have done this challenge by now. I just never got round to it as I didn't get a 6 star Guilly for a while. I think Longshot would do a similar job to Diablo. 7 star Guilly was the star of the show and void too was epic.
