Grats ! I am still feeling the sting of frustration. I've mostly been doing Lilly/Altri/Darvan/Lilith/Lilith with friend Grah. I usually lose to lame damage spikes ( double destiny on darvan ? sure, why not ), but defensive coverage is still a problem - I tried your suggestion of swapping a darvan to leader and swapping a lilith for zelnite, but I found that even harder to maintain BCs - couldn't keep a good uptime on her buff with having to guard all the time.I beat him/her earlier today.
Lilly as a lead is not necessary, ESPECIALLY with her 6* / SBB now, she does just fine as a unit in the party. My only healer is Rashil. Do not rely on Melchio as your status remove / prevent unit as his buff can be removed. It can be done with some luck, but i found it too inconsistent.

I tried with 2x Lilith at first, but Zelnite makes it 100x easier. Lodin would even work. I just used him as a battery and ignored using his BB at all unless I needed it. I was able to heal/darv guard 95% of the turns. I made use of Zelnites damage after the resurrection by dumping the rest of my Fujins into him. I frogged Darvenshel and Zelnite. Zelnite had legwand/sol on and Darvenshel Dandelga/evil shard. If I were to do it again I would have gave Darv a sol also and Rashil my one evil shard. Rashil anima has plenty of health. (Themis should be ok too if Anima)
The best way to reduce luck factor and make it smooth is to increase the amount of BB's Oulu/Darv and your healer can get off as much as possible. Also counters losing track of turns / swipe errors / etc.
I'd like to try Lilly/Darvan leader combo, having two darvans should cover holes pretty well - this is proving troublesome because all the darvan friends I invite immediately switch to random rubbish ( michele ? really ? ) and never change back ! Are you able to friend me (9208843668) and have your darvan as leader when you aren't using it for a bit please ? 8)
