The Obsidian Swordfish can be fished for in bodies of lava using the Hotline Fishing Hook in the Underworld during Hardmode. It's a rather powerful melee weapon with 70 damage and 24% critical strike chance.
- It is one of the strongest spears in the game, only losing to the North Pole.
- Since it's easy to get the Obsidian Swordfish (After you complete the 25th quest of the Angler, he can give you the Hotline Fishing Hook, used to fish in lava and get this weapon) it's a good way to start hardmode. However, it may take some time to receive it, as you can only do one quest each day.
- Added to the game.
