[QUESTION] Thanny Boy Manual

The thing is about chaos is alot of it is unsure and still ppl are finding out stuff about it, like i haven't been able to get any rare armor drops from under hammer, or i haven't been able to get drops for thunder hammer weapons, since now u can create stuff in forge. But i think they made the drop rate % calculator (if thats not understand able look at it like this, there is a line of 100%, say the drop rate is 50% of that line, there is also a lil pointer that randomly stops somewhere on that line and it hits the 50% that doesn't give u the manual, thats what the % drop rate calculator is to me) but they made it to where it drops off more on the side or parts (cuz i cant be for sure how it works) that don't give it too you......if im wrong please correct me cuz this is how i pieced it together and thought of it
