I beat it several times with premade FC group. However before that I had zero luck in DF. It just doesn't seem DF friendly. Mainly because you pretty much have to memorize P3 abilities so you can pre move out of ripples. People need to pay attention to bomb pattens as well and that doesn't happen with randoms.

Somewhat annoying how you have to bother FC people every time you want to finish a relic to kill Titan.
