The flip side of Renewability is non-renewability -- items and resources which may or may not be common, but cannot be created within a single world.
On the Desktop version and Mobile version, any item that can go in the player's inventory can be researched and duplicated, making them all infinitely renewable, but only for Journey characters in Journey worlds.
Non-renewable items include the following:
- Some blocks are created with the world, and may be quite plentiful, but cannot actually be crafted or otherwise created. This applies in particular to most Soil types, and to the Queen Bee and related items. This normally becomes an issue only when a player has explored the whole world, and undertakes to rebuild it entirely.
- 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 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 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.
- Most NPC quest rewards are renewable, but there is a special case : The Fuzzy Carrot and the Angler armor set are one-time rewards, so each player in a world can only get one of each.
Naturally, any item which can be purchased, gained from a drop, or crafted from renewable materials, is perforce renewable.
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 a few can be created in-world: Sand (Antlion, Sand Gun), Granite (Granite Golem), and Snow (Frost Legion); in the Desktop version and Mobile version, also Dirt (Dirt Bomb), Mud (from Dirt near water or a Sink) and Stone Block (Rock Golem, Gem Trees).
- Ignoring variations of grass, moss, and biome conversion, that leaves Clay, Silt, Slush, Desert Fossil, Hardened Sand, Sandstone, Ice, Thin Ice, Ash, and Marble as plentiful but non-renewable. This extends to items created from the above materials, including:
- 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 (Bee armor, Beenade, Hornet Staff), plentiful but non-renewable.
- Some types of natural Wall cannot be harvested by the player; even harvestable walls will no longer be considered "natural" if they are harvested and replaced.
- Hellstone is arguably plentiful, but still finite, including its bricks.
- The Amber Mosquito.
- The following items are non-renewable:
- All craftable Statues.
- Other Bricks not listed above, mostly due to using Stone or Mud. Exceptions include Sandstone Brick (made from sand), Rainbow Brick (enemy drop), and Snow Brick.
- Chlorophyte Ore is created by replacing mud, which can be crafted from dirt, but is still technically non-renewable. In practice this makes chlorophyte "nearly unlimited", but it would conceivably 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:Farming Resources.
- Furniture sets: Flesh and Skyware, due to using Stone.
- Gems are found placed in the world, or spawned from spending Silt, Slush, and Desert Fossils on an Extractinator. Therefore gems (including Amber), are non-renewable. Note that it is possible to deplete a world's Extractinator blocks, especially in a small world.
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. It also covers most of the special chests from these structures, and most Trap blocks.
- Varied Locations:
- Many particular Paintings (see page for details)
- Several decorative Banners (see page for details)
- Assorted Chests (see page and/or list below)
- The Enchanted Sword or Arkhalis.
- Sky Islands:
- Cloud blocks (including rain and snow cloud).
- Underground and Caverns:
- Underground Desert
- Jungle Temple:
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 in the 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. Some of these chests are common enough to qualify as "plentiful", but random chance can still fail to supply one of their items in a given world.
- Gold Chest (most items are shared with naturally generated Wooden chests):
- Wooden Boomerang
- Enchanted Boomerang
- Wand of Sparking
- Herb Bag
- The herbs and seeds it contains are renewable.
- Band of Regeneration
- Magic Mirror
- Cloud in a Bottle
- Hermes Boots
- Identical to the renewable Sailfish boots.
- Shoe Spikes
- Flare Gun
- Lava Charm
- Gold Chests in Pyramid:
- Frozen Chest
- Ice Mirror
- The following items are only non-renewable in the Console version, Old-gen console version, and version. In the Desktop version and Mobile version, all of them can be found in Frozen Crates and Boreal Crates.
- Ivy Chest
- Living Mahogany Wand
- Rich Mahogany Leaf Wand
- Honey Dispenser
- Bee Minecart
- The following items are only non-renewable in the Old-gen console version and version. In the Desktop version, Console version, and Mobile version, they can both be found in Jungle Crates and Bramble Crates.
- Living Wood Chest
- Skyware Chest
- Water Chest
- Web Covered Chest
- Shadow Chest
- Demonic Hellcart
- The following items are only non-renewable in the Console version, Old-gen console version, and version. In the Desktop version and Mobile version, they can be found in Obsidian Lock Boxes, which can be found in Obsidian Crates and Hellstone Crates.
- Mushroom Chest
- Sandstone Chest
- Dead Man's Chest
- The five-out-of-six Biome Chests in the Dungeon: Desert, Frozen, Jungle, Hallowed, and either Corruption or Crimson.
Non-renewable Crafting Stations[edit | edit source]
It seems worthwhile to summarize those crafting stations which are non-renewable (as listed above).
- Lihzahrd Furnace
- Hellforge (and the Hardmode Forges)
- Alchemy Table
- The following crafting stations are only non-renewable in the Console version, Old-gen console version, and Mobile version. In the Desktop version, they are sold by the Steampunker if the player fulfills varying conditions.
Becoming Non Renewable as the Game Progresses[edit | edit source]
Some items may be renewable in a new world, but they become non renewable as the game progresses:
- Gray Zapinator is renewable from the Traveling Merchant Pre-Hardmode after any Boss kill, but it is replaced by Orange Zapinator in Hardmode.
- All Pre-Hardmode crates are replaced by their Hardmode versions, thus making them non renewable in Hardmode.
- Bone Key becomes non renewable after defeating Skeletron.
- Cascade, renewable after defeating Skeletron, becomes non renewable in Hardmode as it's replaced by Hel-Fire.
- Town pet licenses and Advanced Combat Techniques become unavailable once a character used one in the world.
- Similarly, Demon Heart and Torch God's Favor become unavailable for a character if they used one.
