I just got my first wellness fruit in the mines on the Savannah, and it jumped me from 400 hp to 714 hp. I thought it was a lot, and then I saw on the recap for the night, that it should have given me +45 instead.
I visited the Savannah for the first time that day, but went back to my farm after the first level, to get my sword. I used a warp sesajen for that, that I crafted in the mine. I then went back to the Savannah and in to the mines again, going to level 25, and receiving my wellness fruit.
I play on Steam, with keyboard and mouse 🙂
