Reaper pillager (mini boss)

This new mob will be a rare spawn in the new caves. It will be directly hostile towards the player; spawning other mobs around it. These mobs will also be hostile towards the player. It can even have a small chance to spawn a warden or higher. Once you injure it enough, it will fall over and become incapacitated. You can tame it by giving it lapis. Once it is tamed, you can trade with it; using lapis as a trading item. The trades usually consist of mob eggs and sometimes spawners. Hitting the Alchemist will cause it to become hostile and you will have to take it again. It also has a chance to spawn in a raid (level 2 or higher) in which case, it will heal other pillagers nearby, making them your top priority. Times of incapacitation vary, ranging from 20 seconds to 2 minutes. Another feature is, any passive mob, with the exception of pets (dogs, cats, axolotls), golems, and villagers, will become directly hostile, but will have low attack damage.
