Fishing in lava in Terraria is a unique and rewarding activity, introduced in the 1.4 Journey’s End update. It allows players to catch exclusive fish and items only available by fishing in lava. Here’s a comprehensive guide on how to successfully fish in lava, including what you’ll need and tips to optimize your catches.

Equipment Needed for Lava Fishing

1. Fishing Pole:
   • Hotline Fishing Hook: One of the only rods that can fish in lava by default. It has a 1/75 chance of being obtained from the Angler after completing 25 quests.
   • Lavaproof Fishing Hook: An accessory that allows any fishing rod to fish in lava. It can be obtained from Obsidian or Hellstone Crates, which are caught by fishing in lava.
2. Bait:
   • Lavaproof Bug Net: Allows you to catch critters in lava, which are then used as bait. This special bug net can be purchased from the Angler after completing 15 quests.
   • Lava Critters: Includes Magma Snail, Lava Fly, and Hell Butterfly. These can be used as bait and have better bait power compared to regular bait, making them more effective for lava fishing.
3. Lava Fishing Specific Items:
   • Lavaproof Tackle Bag: Obtained from Obsidian Crates and Hellstone Crates, it combines the effects of the Angler Tackle Bag and the Lavaproof Fishing Hook, allowing any fishing rod to fish in lava and reducing the chance of bait consumption.

Tips for Lava Fishing

• Location: You can fish in any pool of lava, but larger pools may provide better odds of catching something. Create large lava pools by using buckets or diverting lava flows in the Underworld.
• Preparation: Make sure you’re prepared for the environment where you’ll be fishing, especially in the Underworld. This includes having adequate protection against lava, enemies, and other environmental hazards.
• Optimal Time and Weather: Like other types of fishing in Terraria, certain times and weather conditions can affect your fishing power. Fishing during a rainstorm, for example, increases your fishing power.
• Fishing Potions: Use a Fishing Potion to increase your fishing power by 15%, which can significantly boost your chances of successful catches in lava.
• Sonar Potion: This potion allows you to see what you’ve caught before reeling it in, saving your bait for only the items you want.
• Lava-proofing: Equip items that grant immunity or resistance to lava, such as the Lava Charm, Obsidian Skin Potion, or Terraspark Boots, to ensure you can fish comfortably in lava-rich areas without taking damage.

What You Can Catch

• Obsidian Fish and Flarefin Koi: These can be used in crafting various potions.
• Obsidian Swordfish: A powerful early-Hardmode weapon.
• Obsidian and Hellstone Crates: These crates contain useful items and ores, making them highly valuable for resource gathering.
• Lava Serpent Bowl: A decorative item or pet housing for a Lava Serpent.

By following these guidelines and properly equipping yourself, you can maximize your effectiveness in lava fishing and unlock all the unique benefits it has to offer. Lava fishing not only adds an exciting layer to Terraria’s fishing mechanic but also provides access to materials and items that are crucial for progression in Hardmode.
