Maxwell Omni guide. I'll have this fully finished and in-depth details when I care enough to do so.

First Battle: Juggernaut

Extremely annoying, hits fairly hard too but nothing to really worry about. Well thought teams should breeze this no problem. Thunderstorm every 4 turns, massive AOE

Abaddon phase 2

60 and 30% launches off 4 death gates, extreme chance to kill without UBB. Targets are two top and two bottom row units.

Every three turns starting with Jugg, buff wipe and ST HEAVY one unit.

Battle 2:

Maxwell Goddess of Creation

Runs identical to her trial 3 version, turn counting an all, except meteor now deals 10,000 damage. Endless at 75%, Transforms at 50%.

Phase 2: Wisdom Goddess Maxwell

If you made it this far, congrata. Now die.

Maxwell will start going ape crazy with buff wipes and Resist lowers.

She will continue to use Destiny Sacred Song and Rune as usual.

She begins to do a new targeting mechanic, where she will select a unit at random, and that unit will get nuked if not swapped out.

Every 6 turns uses Records of Destiny, which is a heavy Buff wipe ST. can be canceled by pushing a threshold, or using UBB to trigger the HP 1 attack.

At 60%, Records of Destiny is used twice every 6 turns.

50% everyone gets a BB reduction per turn.

40% she will start Targeting multiple units. Or at least this is when it happened for me.

20% Uses Overdrive, Next turn using UBB, granting her Massive Damage, All elements, Crit and Elemental Weakness Damage bonus.

If you ever use UBB, She removes all buffs, reduces HP to 1, absorbs your BB gauge. Also gains Self Attack and Defense, in addition to a hit count buff. Don't provoke this unless you're in dire circumstances. This won't proc when she's using UBB.

She regenerates 440,000 HP for every unit she kills.

And voila. Done. Good luck and happy hunting. Got the guide from Gaym and filled in what I noticed as it went on.

A quick TIP for finishing her off when you're at the end:

Save a Hero Jewel 2 fujin and a normal hit UBB,

Hope RNG blesses you and you end up with getting sacred song right before you kill her, or plan wayy ahead for this. Let her pop the Angel idol, then use your UBB, this will delay her Sacred Song use, her using the 1HP BB drain nuke, letting you have an extra turn between Sacred Songs, and then use your normal hit UBB to finish her off.
