Sharks are uncommon aquatic creatures that are very resistant to knockback. They can easily kill a player who is unprepared, and are one of the few creatures of the ocean that has useful drops.
- Due to their wide hitbox and the surrounding water slowing projectiles (some spells not affected), Sharks are highly susceptible to piercing attacks, as they can potentially damage the Shark multiple times. Flails are particularly effective, with a single well-aimed, well-timed attack scoring up to five hits with ease.
- The fastest way to get a Diving Helmet is to set up a Shark Trap, like the one shown in the video below. A space of 8x2, Sharks and Jellyfish have no trouble beaching themselves on the lava shelf. By having the wooden platforms at the water level, the lava won't eat through it. Then you simply stand in a little pool of water inside the house to attract all the sharks and Jellyfish you could ever want while you remain safe inside.
- Another way is to build a long string of Wood Platforms across the top of the ocean. Float around and bait a shark towards you, then use your Grappling Hook to pull yourself up to the Wood Platforms and out of the water. As the shark swims back in to the murky depths, bombard it with explosives. Sharks will usually die from 4-6 Grenades.
- Sharks do not spawn in Corrupted or Hallowed Oceans. If your oceans have been Corrupted or Hallowed, bring along some Purification Powder or a Clentaminator.
- An effective and AFK-able method of farming Diving Helmets would be to use Dart Traps and set them up with timers, preferably 3 Second Timers. Dart Traps have infinite amount of ammo; however, they only shoot every 3 seconds.
- In order to make these work, you must either: a.) build Dirt Blocks in the place where you desire the air pocket to be and then Pickaxe the location afterward, or b.) dig under the location you build your shark trap as to let the water sink and have an air pocket appear.
- If you have fought the Solar Eclipse beforehand, you may have a small chance to obtain the Neptune's Shell which makes you move without restrictions in water. This becomes helpful during such water-based fights.
- Very rarely, when a shark is killed it drops an Orca Banner instead of a Shark Banner.
