3rd boss, the Giant allay

What if there was a third boss called the Giant Allay? To get to the Allay's cave, you need to give a regular allay a nether star and the Allay will lead you there. If you happen to find one of these caves without an allay you will not be able to enter because that would ruin the fun of finding a nether star. If you have an allay guide, you may enter the cave. The giant allay will have 300 health and will deal 5 damage to people without armor. What if the Allay also had thorns 3 so you need instant health potions to defeat it? Upon defeating the Giant Allay you will receive a special chest plate called the allay chest plate and also an enchanting book called health that gives you 5 more health, that can only be paired with the allay chest plate. Unfortunately, the chest plate has the same durability as a gold one so it won't last long. The protection that the chest plate gives is equivalent to a chainmail one.
