Fishing and Alchemy

By ScotUpdated Sources checked

Tactical Quick Answer

Fishing in Terraria generates ores, potions, and traversal gear, not just fish. You need a fishing pole plus bait caught with the Bug Net, and a pool of water. Seventy-five connected tiles is the bare minimum and it costs you 75 percent of your Fishing Power, so dig to 300 tiles for no penalty at all. Pair that with an automated herb farm in Clay Pots or Planter Boxes so you can brew Ironskin, Endurance, and Lifeforce potions for late-game boss fights.

Fishing is a vital engine for generating resources, potions, and advanced traversal gear, and far more than a supplementary minigame. Combined with a well-stocked botanical farm, fishing lets you bypass tedious mining and brew the buffs that decide close boss fights.

Everything here runs on one hidden stat: Fishing Power. Your pole sets the base, your bait multiplies it, and then pond size, time of day, weather, and moon phase all scale it. Dawn and dusk are worth 1.3 times, rain 1.2, a full moon 1.1, while midday and midnight cost you 20 percent. Accessories stack on top, with the Angler Tackle Bag and Angler Earring worth up to 30 between them and each piece of Angler or Captain armor another 5. One more thing worth knowing before you start: without a High Test Fishing Line or a Tackle Bag, one catch in seven snaps on reel-in and the bait is consumed anyway.

Fishing Mechanics and the Angler​

To begin fishing, you need a fishing pole and bait. The Merchant sells the Bug Net, which you use to catch fireflies, worms, and grasshoppers.

Once equipped, cast your line into a body of liquid. Size is the part most players get wrong. Water and lava both need 75 connected tiles for fishing to work at all, but a 75-tile pool cuts your Fishing Power by 75 percent, and the penalty scales smoothly up to 300 tiles where it disappears. Build to 300. Honey works at 50 and optimizes at 200. The Ocean demands 1,001 either way.

Lava is not a drop-in substitute for water. You need a Hotline Fishing Hook, a Lavaproof Fishing Hook, or an Underworld critter such as a Magma Snail on the bait slot, so treat it as its own project. Honey never produces crates. You cannot fish in Shimmer at all, because the bobber just inflicts Shimmering and cancels the cast.

The Angler NPC​

The Angler is a unique NPC you rescue as the Sleeping Angler, in the Ocean biome at either far edge of the world. He spawns randomly on the sand or floating on the water instead of being placed at world generation, so you may have to wait at the shore or leave and come back. Wake him, give him a vacant house, and he assigns one fishing quest per day. The quest rolls over at 4:30 AM whether or not you spoke to him. These quests reward you with exclusive fishing accessories, bait, and currency. Since 1.4.5.7 you can pick up a Quest Fish even while you are already holding one of the same type, so a duplicate catch no longer sits on the ground taunting you.

Consistently completing these quests is critical. The Angler hands you the Golden Fishing Rod, the best pole in the game at 50% Fishing Power, guaranteed on your 30th completed quest. Quest counts live on the character and not the world, so quests you finished in other worlds still count toward the 30. Claiming it unlocks the Glorious Golden Pole achievement, which is the achievement's name and not the rod's.

Fishing Crates​

Fishing yields consumable fish, but it also yields crates. There are 13 crate types, each with a pre-Hardmode and a Hardmode variant. Wooden, Iron, and Golden crates drop anywhere and become Pearlwood, Mythril, and Titanium once you kill the Wall of Flesh. The other ten are biome locked, from Jungle and Sky crates to Obsidian crates caught in lava.

Hoarding pre-Hardmode crates to open after the Wall of Flesh does not work. Version 1.4.0.1 split every crate into pre-Wall and post-Wall variants specifically to close that loophole, so a crate you caught before Hardmode holds no Hardmode ore no matter when you open it. The goal is still sound, just reversed: fish after you enter Hardmode. Hardmode crates hand you Hardmode ores and bars without smashing a single altar, and Defiled and Hematic crates carry Cursed Flames and Ichor while Divine crates carry Crystal Shards and Souls of Light.

Botanical Automation​

Almost every potion starts with Bottled Water, which you make from an Empty Bottle at a sink or any pool of water. From there most recipes want herbs. Only 16 potions want a fish, including Endurance, Lifeforce, Rage, and Wrath, and that overlap is the real reason fishing and alchemy belong in the same chapter. Relying on naturally generating herbs is inefficient, so establish an automated botanical farm.

You also need somewhere to brew. A Placed Bottle works from the start. An Alchemy Table, found in the Dungeon after Skeletron, gives every ingredient a 1 in 3 chance not to be consumed, which is worth up to 50 percent more potions from the same farm. Throw an Alchemy Table into Shimmer and you get the Alchemy Flask, added in 1.4.5, which keeps that saving and also makes newly applied buffs last 20 percent longer.

Craft Clay Pots or buy Planter Boxes from the Dryad and lay them out in long rows. Since 1.4.5 she sells all eight with no boss requirements. Any herb grows in any box regardless of its theme, so they are interchangeable, and Planter Boxes double as platforms you can walk on and drop through. Plant the seeds, which come from harvesting blooming herbs or from Herb Bags, since the Dryad does not sell them.

Harvest at the blooming stage and you get 1 herb plus 1 to 3 seeds. Harvest a merely mature herb and you get the herb but no seeds, which slowly drains the farm. A Staff of Regrowth raises that to 1 or 2 herbs and 1 to 5 seeds, and since 1.4.5 it replants for you automatically. Herbs in pots and boxes ignore nearby swinging tools, so bring a pickaxe or a Regrowth tool.

Blooming Conditions​

The engine gates blooming on environment and time. Each herb also grows only on its own soil, or in any Clay Pot or Planter Box.

  • Daybloom (grass or Hallowed grass): blooms during the day, 4:30 AM to 7:29 PM.
  • Moonglow (Jungle grass): blooms at night, 7:30 PM to 4:29 AM.
  • Blinkroot (dirt or mud): blooms at random and glows when it does. It also reverts at random, so harvest it on sight and not on a schedule.
  • Deathweed (Corrupt or Crimson grass, Ebonstone, Crimstone): blooms during a Blood Moon, or on a Full Moon night. A Full Moon during the day does nothing.
  • Waterleaf (sand or pearlsand): blooms only while it is raining.
  • Fireblossom (ash block or ash grass): blooms only between 3:45 PM and 7:30 PM, and rain cancels it. Since 1.4.5 rain only cancels it in layers that actually get rain, so Underworld Fireblossom keeps blooming through a storm. It still only blooms at sunset down there. What the Underworld changes is growth speed, which is much faster.
  • Shiverthorn (snow or any ice): the slowest to bloom, but once it blooms it stays that way until you harvest it.

Only Fireblossom grows in lava, only Moonglow and Waterleaf grow in water, and nothing grows in honey or Shimmer. Put a herb in the wrong liquid and the game destroys it.

With a stable supply of fish and herbs you can brew Ironskin, Endurance, and Lifeforce, and stacking all three is the difference between surviving a Master Mode boss and watching the death screen. Ironskin adds 8 defense from Daybloom and iron or lead ore, so it is available on day one and needs no fish at all. Endurance adds 10 percent damage reduction and wants an Armored Cavefish. Lifeforce raises your health cap by a fifth and wants a Prismite fished out of the Hallow. Ironskin wins against small hits and Endurance wins against big ones, so run both.

Several other potions moved in 1.4.5.7 and are worth a fresh look at your brewing bench. Warmth Potion now cuts Chilled duration by 75 percent and Frozen by 50. Flask of Nanites adds 5 percent to your total melee and whip damage on top of everything it already did, and Flask of Venom inflicts the new Potent Venom debuff alongside Acid Venom. Super Mana Potion restores 400 mana instead of 300, and its recipe changed to ectoplasm, fallen stars, and greater mana potions. The Mana Regeneration Potion still pins you to the maximum regeneration rate, and it finally applies while you attack.

Frequently Asked Questions​

How big does a fishing pond need to be in Terraria?

Water and lava both need 75 connected tiles to work at all, but a 75-tile pool costs you 75 percent of your Fishing Power. Dig to 300 tiles and the penalty is gone. Honey works at 50 and optimizes at 200, and the Ocean needs 1,001.

Where do you find the Angler NPC?

In the Ocean biome at either far edge of the world, asleep on the sand or floating on the water. He spawns randomly and is never there from the start, so you may have to wait or come back. Wake him, give him a house, and he offers one quest per day, resetting at 4:30 AM.

How do you get the Golden Fishing Rod in Terraria?

It is guaranteed on your 30th completed Angler quest, and the count follows your character across worlds and not the world itself. Claiming it unlocks the Glorious Golden Pole achievement, which is the achievement's name and not the rod's.

Are fishing crates worth saving in Terraria?

Not the pre-Hardmode ones. Version 1.4.0.1 split every crate into pre-Wall and post-Wall variants, so a crate caught before Hardmode never contains Hardmode ore whenever you open it. Fish after you enter Hardmode instead, and those crates give you Hardmode ores and bars without smashing an altar.

When does Fireblossom bloom?

Between 3:45 PM and 7:30 PM, and rain stops it. Since 1.4.5 rain only blocks it in layers that actually get rain, so Underworld Fireblossom blooms through storms, though still only at sunset. The Underworld makes it grow faster, which is a different thing from blooming.
