Then I used Every rose has its thorn to lower stress even more and give a stress resistance(pretty important to continue more easily) and finally, once they have stress resistance, I use Psych Up on the abomination to increase the damage output even more(so much even that it becomes disgusting). Once I reached the firecamp, I gave my team armor penetration with Snake Eyes(which makes the following fights much easier.), as well as using Pray to lower stress and give additional resistance. I went through the first phase easily, having sometimes the curio heals actually be useless. The fights went well, Almost always full health, I was mostly trying to keep the buffs up and lowering stress while killing all the enemies in one round.

So, after that(and seeing how ridiculous the mildred's locket was to beat the miller), I made a party to try to deal with every type of situation(ideally), and set up once again in the endless harvest.

I died at the Miller after some tries, and then, I decided to make a fun party build for this challenge specifically(and start using trinkets). Unlocking the crystal heroes, I went on and tired two or three times with somewhat random parties and no trinkets(I didn't realize they could die without problems). I've been enjoying the game so far, I was a bit scared at first of the endless harvest, but I quickly realized that you could use some heroes to their full potential here.
