Information.svg Note: In Terraria, an item or block is considered "renewable" if it can be created indefinitely within a single world. This guide discusses resources that are renewable without creating new worlds or drawing on previous game worlds.

In Terraria, an item or block is considered "renewable" if it can be created indefinitely within a single world. While a player can create any number of worlds and loot them, that is simply beside the point. Structures are made of blocks, furniture and perhaps other items, each of which may be renewable or not.

There are many ways a given resource can be renewable:

  • Any Items obtained by killing various enemies, bosses, or NPCs. Nearly all enemies and all NPCs can be respawned infinitely.
  • Any item bought from NPCs, and almost any item gained from them as quest rewards.
  • Money itself is renewable, gained from both enemy drops and by selling renewable items to NPCs. For tips on making money in large quantities, see Guide:Making money.
  • Any item produced by Fishing, either as a direct catch, via Crates, or even (with a few exceptions) as Angler rewards.
  • Any item which is crafted solely from renewable items is itself renewable, even if it requires a non-renewable crafting station (see below).
  • Use of game mechanics allows indefinite spawning or duplication of some items:
    • Some items can be farmed by planting the appropriate seeds.
    • Others will spontaneously spawn in predictable environments.
    • Liquid behavior allows a number of ways to combine liquids, increasing their volume over time, and also to create certain blocks by combining them.
    • Miscellaneous methods such as using the Sandgun with ammo-reduction effects.
  • An item is still considered renewable if it it can only be obtained indefinitely during particular game stages, e.g. "before Hardmode", "after killing Plantera", etc.
  • Some items are associated with one of the two possible "evils", Corruption or Crimson.
    • Any given world will only spawn with one of these, all items and resources tied to the other are not available, let alone renewable, by the standard of this guide.
    • However, if "the other evil" is seeded into a world, the renewable resources tied to it will then become renewable in the altered world.

Conversely, non-renewable items include:

  • Some items are found in specific Chests, of which a limited number spawn with a world, and a few of those cannot also be obtained by fishing. Most of the chests themselves are also non-renewable.
  • A few items are created with the world in particular locations, and cannot otherwise be created in world. This includes furniture and materials from several fixed structures, notably the Dungeon, the Jungle Temple, the Underworld's Ruined Houses, and Altars. These structures also tend to include location-specific chests as above.
  • Some blocks are created with the world, and may be quite plentiful, but cannot actually be crafted or otherwise created.. This applies to most Soil types except for Sand, Granite and Snow. It also applies to Hive blocks, and therefore to the Queen Bee's drops.
  • Some types of natural Wall cannot be harvested or crafted by the player. In some cases, this is relevant to game mechanics and/or game balance.
  • Any item which requires a non-renewable item in its crafting recipe.

Renewable Resources[edit | edit source]

Plant-based Resources[edit | edit source]

See also: Guide:Gardening
  • Wood is arguably the most common renewable resource. Chopping down Trees will yield "biome-specific" Wood according to the blocks that the tree was growing on. Most trees also drop Acorns that can be planted to grow new ones. Jungle trees don't drop acorns, but can still be planted, or they can spontaneously grow on Jungle Grass.
  • Hay is produced by cutting tall grass with a Sickle.

Landscape Blocks[edit | edit source]

  • Sand, and by extension, Glass, is an infinite resource if you have the right equipment:
    • Antlions can shoot projectiles that create more Sand, albeit very slowly.
    • A Sandgun used with ammunition-conserving equipment, can place more sand than it uses, thus "farming" sand.
    • By extension, Ebonsand, Crimsand and Pearlsand are also renewable, since (in Hardmode) the normal variant can be converted by game mechanics prior to harvesting.

Ores[edit | edit source]

While mining ore is not renewable, and an Extractinator requires non-renewable blocks, most ores and their bars are renewable through various means. (The exceptions are Hellstone and Chlorophyte, see below.)

  • Pre-Hardmode basic ores: Copper, Tin, Iron, Lead, Silver, Tungsten, Gold, and Platinum can all be obtained by opening Wooden Crates (the bars can also be found in other Crates) or from Slimes as bonus drops.
  • The "evil ores", Demonite Ore and Crimtane Ore, are dropped by their respective biome bosses (Eater of Worlds for Demonite, Brain of Cthulhu for Crimtane), and by the Eye of Cthulhu.
    • As above, if the other evil biome is transported into a world, its ore becomes renewable, however, the Eye of Cthulhu will still drop only the world's original evil ore.
  • Meteorite ore is produced by meteorite crashes, which appear after smashing a Shadow Orb or Crimson Heart. The crash sites convert a chunk of landscape into the ore, and also spawn Meteor Heads, which (before Hardmode) can also drop Meteorite ore. Note that meteorites do chip away at the landscape, but the player can place more (renewable) blocks for them to convert.
  • As with the pre-Hardmode ores, Cobalt. Palladium, Mythril, Orichalcum, Adamantite, and Titanium are all renewable, as these can be found in Crates during Hardmode.

Game mechanics[edit | edit source]

Other Resources[edit | edit source]

  • Again, money and all items purchased from NPCs are renewable.
    • Most NPCs have items to sell, the exceptions being the Guide, Nurse, Angler, Tax Collector, and Old Man.
      • Visit the vendor NPCs' respective pages to view the items they sell.
    • Coins are both dropped by enemies and gained by selling items to NPCs.
    • Defender Medals are gained from the Tavernkeep and by fighting the Old One's Army event.
    • Each NPC can also drop specific items when killed by the player.
  • Likewise, any item dropped by an enemy is renewable. While enemy drops are too numerous to list here, some of them warrant special mention.
    • Gel is dropped by every type of Slime, making it not only renewable but plentiful.
      • Desktop VersionConsole Version Unlike other slimes, Pinky drops Pink Gel. It is still renewable, but harder to get in large amounts.
    • This also covers Tissue Samples or Shadow Scales (according to the world evil), Hallowed Bars, and Luminite, dropped by Hardmode bosses.
    • Sturdy Fossils are dropped by Basilisks in Hardmode.
    • An unorthodox case: Demonite Brick is technically renewable in Corruption worlds, despite the ebonstone in the recipe being non-renewable, as small quantities are created upon killing the Wall of Flesh. Likewise, for Crimtane Brick in a Crimson world.
  • Items obtained by Fishing are all renewable. Visit that page to view all Items obtainable from fishing. Most ores and bars (see above) can be obtained by way of Crates, as can many weapons, tools, and accessories, and even a crafting station.
  • All Dyes are renewable:
    • The "basic" dyes fall under one or another of the renewable categories: Plants that spawn spontaneously, enemy drops, or purchased.
    • Quest-exclusive Dyes can be obtained from the Dye Trader as long as Strange Plants can grow to trade them in.
    • All other dyes can be crafted from basic, purchased, and/or quest dyes.

Non-renewable Items[edit | edit source]

Non-renewable items are few enough that they can be listed individually. A few of those are "semi-renewable", produced by something that is plentiful but ultimately finite.

Plentiful but Finite[edit | edit source]

  • The various Soil types are created with the world, but only Sand and Granite (and sometimes Snow) can actually be created in world. Ignoring variations of grass, moss, and biome conversion, that leaves Dirt, Stone, Clay, Mud, Silt, Slush, Desert Fossil, Hardened Sand, Sandstone, Ice, Thin Ice, Ash, and Marble as plentiful but non-renewable. This extends to items created from these materials, including all craftable Statues, and several furniture sets: Frozen, Marble, Flesh, and (due to the stone needed for their bricks) Skyware, Meteorite, and Crystal.
  • Gems are found placed in the world, but the only other source for them is using an Extractinator on Silt, Slush, and Desert Fossils. Therefore gems (including Amber), are non-renewable, as is the Amber Mosquito item.
  • Hive blocks are found only in hives in the Jungle. Since Hive (or a Larva, which is only generated with the world) is needed to summon the Queen Bee, this makes the Queen Bee's drops (except Bottled Honey), and any item made with Bee Wax, plentiful but non-renewable (but still plentiful).
  • Some types of natural Wall cannot be harvested or crafted by the player; even harvestable walls will no longer be considered "natural" if they are harvested and replaced.
    • Natural walls do not suppress enemy spawning, while any placed walls can.
    • The Dungeon, Spider Nest, and Underground Desert (mini-)biomes are defined by the presence of their respective naturally generated walls.
  • Chlorophyte Ore is created by replacing mud, which can be crafted from dirt, but is still non-renewable. In practice this makes chlorophyte "nearly unlimited", but it would be possible to deplete a world's mud/dirt. This likewise applies to Shroomite and Spectre Bars, which are made from chlorophyte. For tips on "farming" chlorophyte, see Guide:Gardening#Chlorophyte ore.

Location Specific Generation[edit | edit source]

A few items are created with the world in particular locations, and cannot otherwise be created in world. This includes (but is not limited to) furnishings and materials from several fixed structures, notably the Dungeon, the Jungle Temple, the Underworld's Ruined Houses.

Location-Specific Chests[edit | edit source]

Various special chests spawn with a world, and even those chests which have corresponding Crates have a few items which are not found in their crates. In all cases, items are listed under only the first chest they appear in. All of the chests listed below are themselves uncraftable and non-renewable items.

Non-renewable Crafting Stations[edit | edit source]

It seems worthwhile to summarize those crafting stations which are non-renewable (as listed above). Special mention for the Sharpening Station, which is not a crafting station but in some ways resembles one.
