Bosses

Bosses are large, aggressive, resilient enemies that offer a substantial challenge to players. Defeating bosses is usually instrumental in advancing the game in some way. Each has its own particular way of being summoned, and warning messages appear whenever one is about to appear. Defeating a boss concludes with a congratulatory message and several items.

During Hardmode, each night has a one in two chance of spawning one of the three Mechanical Bosses that have not yet been defeated in the current world.

The King Slime is a giant blue slime with 2000 health. It is summoned with a Slime Crown, and can also rarely appear in the outer thirds of the map completely by itself. As with all monsters that can spawn naturally, the King Slime has a better chance of spawning while holding a Water Candle or under the effects of a Battle Potion. The King Slime is a good challenge for a beginning player, and can be easily defeated by tactical use of terrain.

Duke Fishron

Duke Fishron is a Hardmode boss. It is a fish-pig-dragon hybrid with 50000 health and 50 defense. It is summoned when a Truffle Worm is used as bait with a higher-powered fishing rod in an Ocean biome. In its first stage, Duke Fishron will attempt to ram the player 5 times before either firing explosive bubbles or summoning Sharknados. In its second stage, Duke Fishron gains glowing eyes and a boost to attack and defense (needs confirmation.) Although its ramming attacks remain the same, instead of shooting bubbles directly at the player, it flies quickly around in circles, sending bubbles everywhere. Instead of summoning Sharknados in this stage, Duke Fishron summons larger Cthulhunados. These remain in place until Duke Fishron is defeated. is he really mysterious we think he is not real he was created during april 1 though the end
