Not having maxed characters shouldn't be too much of an issue. My Sol, Ky, Elphelt, and Rozalia are only level 12 with UBB and second sphere unlocked. (My Stein is 150 though.)

If you're using Arthur, bring 2 Fujin Potions, 3 Fujin Tonics, and a Hero Crystal. Plus revives if you're worried Elphelt might kill someone on turn 1, or Brute Elixirs and Gleam Stones if all you need is a tiny bit more power. They stack.

Set Sol to force BB. Assign Sol to act after Ky. This is so the def to atk convert buff on Sol's BB is applied after Ky applies his def buff. You will want Ilm and Elphelt to act after those two to take advantage of their buffs. You should be able to fit a fifth omni with these four and 235 cost. The five you named lack a spark buffer among them, so I recommend slotting one in.

On the first turn against the Elphelt on the last wave, activate UBB on Arthur, Fujin him, use his UBB, then push the auto button. If she doesn't die in one nuke, turn auto back off and on the second turn use a Hero Crystal, activate UBB on Arthur, then Fujin him and your three hardest hitters. Then nuke again.

If you don't have that many consumables, go defensive with a Cleria friend. Rozalia is also a good option since she nulls crit, which boss Elphelt tends to abuse when she's low on HP. If you go this way, you will want to put a status negating sphere on Ilm so he's immune to curse plus a BB on hit sphere to augment Cleria/Rozalia's ES. You will also want BB on hit spheres on Elphelt if you have any to spare. GIve Sol, Ky, and your fifth unit a sphere that at least negates curse, and a sphere that boosts all stats, or HP and Def if you're out of those. And if you have any extra HP/Def Elgifs lying around, give one to Ky, Sol, and Elphelt. If you are using Rozalia as a friend, set her to go first and Ilm last so she can charge Ilm's BB gauge with her instafill even on autobattle. Bring both kinds of revives in case someone dies. Some fujins are also a good idea, just in case Elphelt catches you with low HP and no healers ready. I recommend holding your UBB gauge so that your Elphelt can use her UBB when this happens.

And lastly, have you considered making a post on the Squad Building Help thread? You'd probably get a better answer there than on this page. The link is on the top of the comments section.
