Morbid Harvester

The Morbid harvester is a boss added by mob fusion, despite not being any fusion.

Spawning
The Morbid Harvester can only be spawned with a spawn egg. However, it CAN be obtained in survival by crafting a nether star with 4 reinforced endermen scales and an egg.

In Combat
The Morbid Harvester is one of the more powerful of the late-game bosses, and is considered the upgraded wither. The morbid harvester has a high amount of health and must be killed before he regenerates his health. He has 2 main attacks. The first being a deadly stab attack dealing massive damage and the second being a blast of fire dealing double that amount of damage. The harvester can kill you swiftly, so caution, speed, and skill is advised.

Strategy
It is recommended that you have 2 and 1/2 rows of health, swordsmanship, fire resistance, enderman scale armor, and a powerful sword such as the ultimate sword. His attacks cannot easily be dodged and can only be killed reasonably in melee. Golden apples are almost necessary.

Desperation
Upon death, the harvester will make one last ditch attempt exploding into a volley of arrows.

Drops
Despite only having a 40 damage arm as his drop which is now likely obsolete or mediocre unless killed early, the xp yield from the battle is easily enough to gain every row of hearts and even max out quite a few abilities.

Trivia
-The Morbid Harvester is the only non-fused mob from mob fusion.

-The Morbid Harvester is between the point in the game you can get Big Bertha/Slice to kill him easily and the point when you get ultimate gear to beat him in a more challenging way, making the challenge aspect completely optional.
