Star Justice Descended! - All Att Needed

This would be a easy but time consuming dungeon to beat if you go with Thoria combo lead in co-op.
With 70k+ HP and 2x rcv it's almost impossible to die. The only threat is FL4 where you want to kill him asap before the nuke.
Pre boss simply don't do enough dmg to kill you and with boss floor just chip away and heal at the same time till under 50% then just nuke him for the win.

You'd have to say this is significantly harder than all the other dungeons in this descended challenge. Finally beat in co-op with Revo Neptune and Echoes Mion leads. I could use some water orb changers early to get past the first 2 levels, then stall indefinitely on level 4 to reactivate all the active skills again, which are necessary to beat the last levels. When you can block 50 to 75% of all damage (except for fire) and block poison orbs, you can afford to be patient.

Krishna can do this solo, no hypermaxed team.
Krishna +297 / Ronia / Ares (light uevo)/ Urd / Antares (green Uevo)
All Max lvl and skill, only krishna hypered.
inherits: Urd-> Ares, Lumiel -> Antares (though irrelevant)
Krishna friend with Urd inherited.

As long as you use stage 5 to stall and get your actives ready you can OHKO stage six and for seven I just used Ares and killed him. lumiel inherit was irrelevant, there only to make sure the skill down hit leaves Ares ready to activate.

panda, yomi, lubu, beelz, sakuya, panda

sakuya, for yellow/blue attribute and she came in handy to clear a monster 8 turn bind. Her plus a row of hearts cleared up the whole team.
