Ok ash here it is.
So the clues you have given me are: Book:2, and I got both of those.
shades: 3. I only got roof from that
weight: 4. I only got scale and gold from that
So from those clues you have already given me, I'm going to assume one of the clues was duplicate, so I still have all the clues to our words.
From shades, I would guess the other two words are maybe VACATION and MAMMOTH?
From weight, I would say the other two are MAMMOTH and ?
POISON, CZECH, KIWI, GRASS, and STREAM I don't get from either of those clues, which decreases the guessing space to KING, VACATION, DWARF, MAMMOTH. From those I would guess KING as the other weight one?
So two things for you. I'm probably going to guess VACATION, MAMMOTH, and KING unless you change my mind, and make sure you give me a number that allows me enough guesses
