I just observe the last chapter and I realise these is another way to extract a tail beast beside using sharingan or gedo maz
bito demonstrate that once you can touch a certain spot in the tail beast host (Jubi Madara) they can rip out the tail beast .This mean tail beast hosts are vulnerable close combat if the opponent know the method to extract their power.Even if the opponent can extract a small portion of the tail beast host chakra the opponent will still benefit from the chakra taken.
