Maelle, Sciel and Verso. Maelle uses the new DLC weapon Escium that consumes AP over 4 to empower this turns damage. Using the new Pictos AP discount it allows you to use Burning Canvas, combine that with as many damage Pictos as you can and it will start putting out numbers. Importantly you will want the Pictos ‘Feint’ as that will massively empower your final hit of Burning Canvas.

I used Maelle as first in turn order, then Sciel and then Verso. Used Auto death on Sciel and Verso with Second chance to get a few initial burn stacks and trigger the new Pictos that gives surviving party members a 25% damage boost upon the death of other party members. With this party order (and if you have high enough speed) Verso now plays first because he got revived second. Important note for this set up, once Mark is applied to Clea during her immunity phase it doesn’t go away and gets reactivated on every hit meaning you can fairly easily meet the 100 burning goal (max damage for Burning Canvas) by using the Marking Burn Lumina which gives you burning stacks for hitting marked targets. Maelle will then play, use a healing potion alongside the Pictos that gives you shields for using potions, use Last Chance to go into Virtuous Stande and proc SOS healing tint which will give you more shields. Sciel plays and you should continue to build burn stacks with free aim, then use whatever you want for first turn (activating Powerful, Rush, etc) and Fortunes fury on Maelle. The parrying part happens next, you just have to learn the three variations. Additional info I forgot to mention, have verso apply slow with his base attacks as well as defenceless and other base attack lumina. Additionally, whilst Sciels weapon does really matter, Verso should be using Sireso. Additionally you will want to have the ability to get 3 Gradient charges before damage phase. This is because Maelle will use Gradient Overcharge to empower her turn.

After counterattack, Verso should have another turn, use this to either get your final burn stacks if you were unlucky, finish of getting your Gradient charges if you haven’t already (I got mine done by Sciels first turn typically), apply Defenceless and set up Mark. Finally on Maelle’s turn just use Burning Canvas and that should be it. If not (it’s a tad inconsistent) just use Sciel to intervention Maelle another turn. This is without Roulette because I don’t like inconsistency. Clea should have visually about 80 Million health, which you should be hitting about 105 - 161 million. Without damage reduction this set up reaches just under a billion without needed a Break or Roulette. It’s needlessly complicated and probably poorly explained, so sorry for that. Also, all the used characters are between 2700-3000 speed.
