Constructs and ancient ruins

Constructs have a 80% chance of appearing in ancient ruins (which have a 15% chance of appearing). Constructs are 10 blocks tall, have a stone golem body, are in a gorilla position, and have a stone creeper head. They have a fist slam attack and can be built by putting 10 stone blocks up, ( Except that the 8th block is redstone) and 5 stone blocks on either side of the Redstone block, and a creeper head on top, the construct will fight for you. The construct will drop a construct head that you put on your head to gain extra attack and 5 armor, but they are mighty opponents they have 15 hearts, and you have to hit them in the head! P.S construct head can only be enchanted with mending and unbreaking.
