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.
