Cleaning the Temple

At any time after coming back from the mountain, during the day, Axel (or Nauxus, if he is dead, which leads to different dialogue; neutral and bull route also have slight variations) will ask you to help him clean the bull temple.
The quest offers some obscure and trippy lore, and there’s technically a fight with a slime, where you can only attack (for chip damage), bind up or defend, so physical builds and equips are better, but you need to hope it doesn’t use its mucus often, even though it does seem to choose normal attacks more; still, winning or losing just has some variations in dialogue, it’s a free level up point and 500 coins.
