How to fish in Hell in Terraria

Fishing in Hell in Terraria is all about preparation! First off, you'll need a special rod called the Hotline Fishing Hook, which can only be obtained from the Angler NPC as a reward after completing at least 25 quests. Make sure you've got plenty of bait, too, as the lava fish are pretty picky. Then, just find yourself a nice pool of lava and cast your line. Easy peasy, just watch out for the demons!

I tried fishing in Hell once, totally forgot about the special rod. Spent hours wondering why nothing was biting. Turns out, you REALLY need the Hotline Fishing Hook. Lesson learned the hard way, don't be like me!
