TIL OPs password is Hunter 2 <| sep |> Not a bug , unlike other missions which you summon esper and deal damage whatever time as long as you kill the unit in that turn , for this trial you have to time the esper damage to be the last tick or it will not count , i tried using ramuh and diabolos evoke a few ttimes , the only time i complete the mission is when my diabolos do the last tick of damage , before the boss fade and diesAs for not dying , use more tanker and healer and keep the debuff on the boss , watch the 60 % 30 % carefully and guard ur squisy unit accordinglyTook me 5 tries to get all the mission , with the esper being the most annoying <| sep |> Yeah sadly . seems the trials are indeed getting longer and tougher and more like mission impossible
