Duke Fishron

Info
Duke Fishron is the second hardest Hardmode boss the moonlord is the strongest (unless ur in 1.2.4 where moon lord doesnt exist) currently, he is a flying sharkfish with high damage and great mobility. He is summoned by fishing in an ocean using a Truffle Worm as bait in the ocean. Truffle Worms can be caught in the underground Mushroom biome. To defeat Duke Fishron, you need an arena. Make an arena in the ocean, it has to be wide enough for you to fly around with wings, but small enough so that you don't accidently go outside the ocean biome, because if you do... He'll become ENRAGED. If Duke is enraged, his damage and speed increases, so try not to get him angry!
