The Wither King

The Wither King is the of The Master Catacombs - Floor VII.

Boss Fight
The bottom of Master Mode Floor VII contains a giant throne room. There are five relics placed next to dragon statues around the room. There are also five cauldrons in front of the throne near the center of the room. They each have a specifically colored clay below them. The players must bring and place the relics with the same corresponding color as the cauldron's block of clay, otherwise the players fail the run. After placing the relics, The Wither King will be summoned on his throne.

Damage cannot be dealt towards The Wither King, and he mostly acts as a spectator to the battle. The Wither King will spawn one of five dragons, named Apex Dragon, Flame Dragon, Ice Dragon, Power Dragon and Soul Dragon, every 30 seconds. All five dragons must be killed near their corresponding colored dragon statue to destroy them. All dragons can respawn at any time indefinitely until all dragon statues are destroyed. If all five statues are destroyed, the floor is completed.

If all five dragons are alive at any time, the Wither King will send the players into the air in the center of a ritual. The dragons will complete the ritual and summon a giant hand coming up through the floor, grabbing and closing around the players, causing them to fail the dungeon run.

Trivia

 * The Wither King's real name is Kaeman, confirmed by himself during his conversation with Necron in the Journal Entry - The Apprentice 3.
 * The tentacles coming out of The Wither King's body could be based off of the Wither Storm from Minecraft: Story Mode.
 * According to the Piglin Sirih, Kaeman once had a wife named Sarah and a daughter whose name is not revealed. An incident with his daughter drove him to become the Wither King.
 * This is confirmed in the Journal Memories, where it is also stated that his daughter was named Mylah, and that he became a wither by fusing with their corpses (which is why he has two extra heads).
 * When The Wither King is summoned, he has a garbled name.
 * After the which cost him his wife and daughter, he began researching Fel Magic to try and bring them back to life. After seven years, he tried the spell for the first time, which did reanimate them, but they weren't themselves. After Three more years of research, during which Kaeman started venturing further from his laboratory, castle's routine inspection discovered the facility, stole the scrolls, killed Sarah and Mylah and destroyed what was left of the lab. After this loss, Kaeman sought vengeance casting a spell and willing to give his life for it so he could be reunited with his family. That's when he understood the essence of Fel magic, power of sacrifice. After giving up his life, he has gained more power than ever before, this spell also merged him with the remains of his family, with Mylah's head on his left and Sarah's on his right. Fueled by burning anger, he has charged towards the castle, a decade after the Calamity, he would unleash upon them a terror greater than they had ever known.  After this destruction, Kaeman was defeated by mages and imprisoned at the edge of the main island. Someone Kaeman's scrolls from Mages and given it to a young not very successful mage student - Necron. He has learned this spell and used it to help Kaeman free himself, this lead to a disturbance that affected even the Rift Dimension, and created  area there. Kaeman then took Necron to Catacombs. Necron started doing errands for Kaeman, one time he went out to receive a letter from Dr. Emmett via Lanthrop who was supposed to delivered it, however this was interrupted by a young assassin who tried to kill Necron. Livid however failed at this task and was turned into an undead by Necron. Necron then promptly carried Livid to the catacombs, but he was followed by Lanthrop. Necron senses this and asks Lanthrop why is he following him, to which Lanthrop answers that he has seen Necron in visions, when Necron heard this, he encouraged Lanthrop to follow him in Catacombs. There he is introduced to Kaeman who then takes him to the Seeing-Stone, which gives him visions that Lanthrop was followed his entire life due to the Rift above the . Over the next few months, Lanthrop spends several hours a day looking at the Seeing-Stone, which increases his control over his visions allowing him to see into the Kaeman's past and becoming . Watcher was then tasked to reshape the Seeing-Stone for another purpose, so he studied Wither King's past deeper and using the orb, he created a world identical to the one Kaeman used to know. The Wither King then spent days in this realm and said he has no need for Watcher anymore, charging him to be loyal to Necron who has taken over the Catacombs since.
