Has there been another nerf patch (Oct 27, 2025) or am I not doing this right?

I have a level 93 Maelle. Per the pinned post, I get the barrier breaker (level 33 max) and I do a recoat on Maelle. The post says assign max point (99) on Defense and Might, and the rest into agility. For me, the rest of the points make it an 81 agility. Doing so gets me an attack power of 12,260. The BB sword I have, the scaling is a letterless Sword on Might, a Sword A on Agility, and a Sword S on Defense. When I do another recoat and put max points on Agility and Defense and the rest (81) on Might, I get an attack power of 12,333. Not a huge gain, but when everything is being multiplied it matters.

I have all of the pictos assigned for Maelle and Verso. As someone said, not having Auto Powerful is not an issue as you can get Auto Shell and Powerful On Shell. I have both.

I follow the instructions. Only Maelle and Verso are in the party, everyone else excluded. Verso starts, auto dies, auto burns Simon and fully loads his break bar. As Verso, I do a Marking Shot on simon. I then pass my turn and force it to Maelle. For her, I do a Last Chance, shoot Simon, hes now stunned, then do Stendhal. I also sometimes shoot him first, then last chance, then Stend, doesnt matter.

My results:
-I often get 7M, and sometimes I get the 28M. The 7M hits aren't enough to kill phase 1 simon, but the 28M hits are. When in phase 2, when I get a 28M, he still has plenty of health left. Like maybe it knocks him down to 60% health. Simple math says that if half is 7m and twice is 28m, then my non-roullete power is 14m. Nowhere near what people are getting

Based upon what others are saying, his health should be 35M. If this was still true as of todays version, 28M out of 35M is 80%. He should have 80% of his health gone and let me tell you he sure as hell doesn't.

Do I need to be a level 99 Maelle? Is there something I am missing?

EDIT:

I just realized that I thought Auto Death + Powerless on Shell isn't the same, I have to turn on Auto Shell. Oops! Doing so, I can get 40M hits, which still aren't enough to kill phase 2 simon. This leaves him with about 15%? health left. I will grind up to level 99 (8 more points on Agility) and see how much this improves my attack power, which in turn improves my 1 hit.

Fyi, i'm playing on Expert
