What you need?
1. Units that will last the 3 battles
2. Time
3. Concentration
4. Counter - #googlemolang
5. Full charged gadget - my battle lasted for 1.5 hours
What you're up to?
1. Battle 1: Juggernaut (Thunder) - Mitigate every 4 turns. Bring a nullifying status leader.
2. Battle 2: Abaddon (Dark) - If you have a separate squad for maxwell, let the first squad be killed at his 30% attack so your maxwell squad has time to fill up their BB.
3. Battle 3: Maxwell (Light) - Counting is very important!!!
My Squad
Squad 1 was dedicated for the first two battles, Juggernaut and Abaddon.
Squad 2 was for Maxwell.
Squad 3 was just a filler in case something goes wrong.

Counting from the first battle is important to know what mood maxwell's in when you enter battle 3.

I suck at counting. I only remembered to count on my 2nd turn.
Even after I remembered counting, I lost count on my 7th/8th turn so there goes my counting down the drain.
It was a good thing I was able to mitigate every other turn so I was safe with the first 2 battles.
When I entered battle 3, maxwell was in a good mood. I learned which turn I was in the hard way, her 20th turn ( Rune+Sacred Song+Destiny). Good thing mitigation was on and most units were guarded.
Anyway counting is important to know which turn to kill maxwell. She has an angel idol buff so if you don't kill her without it, she will just keep on reviving.
Just follow the instructions on what to do using the counter and you'll be fine.
Aside from counting, you'll also need to take note on the hp percentage when they perform special attacks.
Tridon was a very big help. I think it's the safest and easiest way to get maxwell from what I've heard so far.
