It's okay. I just pugged it and failed because I was the only one to bring someone with paralysis ward. My Kana is always the only one not paralyzed, so that makes it so the person who is not me, have their turn skipped and no one for my Kana to initiate a pincer with when perdition hits. The thing is I had 3 Jennish on the team but no one else brings anyone who can stop getting paralyzed so it's a wipe pretty much soon after Perdition. I am bummed out that one time another character besides Kanna was left unparalyzed but they didn't see it and decided not to initiate a pincer with her so she can cast locomotion. I guess I should just try to find a character to level with paralyze ward, the first half of the fight always go so smoothly until perdition hits.
Also interesting to note, is that Chaos will prioritize Perdition over casting his AoE. We got him down to about 30% with the 3 Jennish real fast, which made him not fire it off until the turn after perdition. Also, Samupi does seem to work pretty well, the Jennish could take some hits from aoes, but of course that is moot when paralysis prevents tehm from acting for a few turns.
