I suggest making Grahdens your lead since he reduces Light and Dark damage by 15% and he gives 20% boost to all units' stats. If you have Tridon, I would suggest making him your lead instead.

Darvanshel is, without a doubt, a definite pick for your squad since he is a damage mitigator. If you level his SBB to 10, his SBB cost will get reduced. Try and use his BB every turn if you can and guard all units whenever Maxwell uses Rune.

If Lancia is your only healer, use her. She might not be a current metagame healer at this point of the game, but she is still a decent healer to use, despite her being outclassed by the most recent healers. Although it might not be much, her ATK buff (which is 50% at SBB10) can contribute to your damage output, especially when you are in a situation in which you need to defeat Maxwell before you fall into the revive loop.

As for your other two sub units in your squad, I highly recommend using a cure-debuff unit like Exvehl, Melchio, etc., and another damage dealer (most ideally, an infinite SBB unit like Rowgen, Lilith, Arus). You can put Dilma as one of your damage dealers. Juggernaut can inflict Paralysis and Abaddon can inflict Curse to your units. Maxwell also casts Sacred Song every four turns so you will need to deal enough damage once she revives or you will be stuck in a loop.

Try and look for a Lilly Matah lead. Unfortunately, I don't have a Lilly Matah so I can't set her as a lead for you, but try to look for one. She'll help a ton when it comes to BB regen.

Now for the other units you mentioned, which are Semira and Azael, they're okay units to use, but it won't help you too much in the long run. Semira has an 80% chance to inflict status ailments, but Maxwell is immune to status ailments so that won't help you. She does have a 30% BC Drop Rate buff, but that buff is only applied to herself and her BC drop checks are very low compared to other units. Additionally, she's a Dark unit so she'll be taking more damage from Maxwell's attacks. As for Azael, he's a pretty good powerhouse in terms of damage, but his SBB costs way too much to use. He is also currently bugged (until the next update) as he has a broken drop check on his SBB.

If you could also list your other units and items, I can help build a squad for you. Also, I'm new to the wiki so sorry if this is a long post. :/

Hope this helps!
