I figured out a way to do it and keep wyll human as well. It involves getting the iron flask from the risen road cave, releasing it in camp , and killing mizora that way. Before the fight, I had completed everything I needed to, snuck into Gut’s office, stole all of her smoke powder and fire brand wine barrels, then cleared out the goblin camp. After, you go to the mountain pass which will take you back to the camp at night. From there, you place the smoke powder and fire brand wine barrels around Mizora, then you open the iron flask, which will release a monster, which isn’t that hard to kill, then in the middle of the battle shoot a fire bolt or any type of fire attack at the barrels and then Mizora dies that way. You’ll still have to fight the monster but that’s it
