I must admit I'm a bit confused by the systems at play here.
I've read
Pretentious Goblin's day by day example and while my team is obviously a bit different, I found it impossible to get breaks on day 12 or 13.
Now, I've been trying to break core before minor, but the general idea should remain the same, stack multipliers and then go for it, with cores being a bit harder due to innate resistance.
But I found that the capture/surround actions do so much excessively multiplied trauma damage that the negative multipliers accumulate so fast, the circumstance damage done is negligible.
Specifically, what I tried to do was get a break on either pleasure or pain for a character who's got core on both, since going for the related trauma raises the negative multipliers, I decided to start on another character, capture and raise expo to get the 2x bonus, once the other appeared, capture, start with grind for the hate multiplier, then go for caress and pummel.
While I was able to gather ridiculous amounts of trauma and had multiple 6+ surrounds on day 13, I couldn't get the five EP back I used for the commander, as trauma started raising in the thousands each turn, while circumstance was in the low double digits.
I tried again, using only grind and caress to reduce the trauma adding up, but after starting those two, the multipliers for fear and disgust were already at 24x, while hate and pleasure were at 2x, due to being halved from high fear and disgust.
The turn after that, disgust raised by 2k, while pleasure only went up by 48.
That halved the pleasure multiplier again, with the final turn of capture resulting in another 2k disgust and 24 pleasure...
Have these negative multipliers from trauma only been added recently, after that day by day walkthrough?
EDIT: No I can see them in the pictures, guess I need to raise someone's expo to the 4x multi to do anything.
Just seems like the surround actions do far too much trauma damage, which makes it impossible to rack up a meaningful multiplier to counter the resistance of cores.
EDIT2:
Alright, I just managed to redo that day 13 battle to get multiple breaks, but only by accepting minor breaks before cores, how one would break cores before minors eludes me.
